General :: Exceed/Exceed 3D Performance Under OpenSuSE 11.2
Aug 3, 2010
We've used Exceed and Exceed3D X server software to run OpenGL 3D simulation software for a long time, and it has always worked great. Now, a new box that runs OpenSuSE 11.2 (kernel 2.6) shows terrible display performance with Exceed.
Exceed 10 on Windows XP works great for OpenSuSE 10 and earlier, but the same display platform grinds to a halt for OpenSuSE 11.2. We tried upgrading to the latest version of Exceed, version 14, but still no joy.
As an alternative, VNC works okay for desktop stuff, but just doesn't run the 3D apps like a dedicated server does (or should).
The reps at OpenText, the makers of Exceed, scratched their heads over this one.

Another basic question, as I am still new to Linux.I have a new machine loaded with RHEL 5.2 and when I try to connect into it using EXCEED XDMCP-Broadcast mode from my PC, it never comes up as a selection in the select-list. What rpms, procs, etc. am I missing on my RHEL 5.2 system???

I have a server which I need to connect to and run a graphical program on. I know that you can do this with Open Text Exceed, but it's been years since I've done this and the last time I did it was on version 9. Unfortunately I only have a license for version 14 now and have no idea how to do this. how I can use Exceed to connect to my linux server?

I presently have Fedora 12 running on a Dell Optiplex with a Pentium 4 CPU. I want to buy a new computer, probably from Dell, I don't completely understand the options I have available for which Fedora 13 will run.I more or less understand what 64 bit means since I also have an HP with an AMD 64 bit processor. But are there other options which will allow me to exceed the i386 memory limit? How about dual processors?
I used to understand CPU architecture pretty well, but i've lost track of more recent developments. Can anyone recommend a primer of CPU types, including assoicated memory limits? Similarly, I would like to be sure that Fedora 13 will run on whatever machine I decide to get. So a list of available processors, which are equivalent to which, and which Fedora 13 has been tested on,

I've checked gdmsetup and there isn't anything that I can see that keeps my general users from getting in remotely. I can get the Gnome to login as root but not as a user. SSH from PuTTY works fine for all users. The error I get actually says that the username or password is incorrect - checked using SSH and it is fine.

I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

First of all, apologies if this is not the correct place to post this. I recently installed openSUSE 11.2 (Gnome, 32bit) on my newish PC. It is an Acer Aspire X3200 (AMD Phenom X4 Quad-Core, 1.8 GHz, 4096 MB, NVIDIA GeForce 8200 Integrated, can provide detailed specifications if needed). I've to say I am very disappointed with the results so far! Sorry to say this but I'm having a whole load of problems that I never had when I had Vista or with current Win 7. Here are the issues:
1. Slow network performance. I've disabled ipv6 but it is still the same. Not only when I use Firefox, it is also slow when I use console based programs. 2. Instability - Gnome system monitor crashed 6 (or more) out of 10 times I use it. System Monitor users more CPU resources than anything else! Also when I started the PC this morning, I only had the desktop wallpaper. No icons, no taskbar, no mouse movements or menus, nothing. I had to force shut down it after a while. I'm sure we all are familiar with this on XP but I've never seen something like that on Linux!
3. Annoying noise coming every time I move mouse (mainly when scrolling) and even if I'm not doing anything. I suspect it is coming from my HDD indicator as it always blink even when nothing is running. This can't be a hardware issue as I've never had this on Vista or Win 7 (it is virtually silent on Vista and XP but not on SuSE) This noise is driving me totally mad.
4. Slow performance in general. No matter what I do, even typing this on this text window, it seems everything is running so slow. I never had this problem when I was running 10.x on my 6 year old PC. CPU is always running around 20%-30%, when I don't run any other applications but just Firefox (I have Foxclocks, Delicious and FEBE as add-ons and I don't have any problem using them on Vista or Win 7). I am using Compiz, not sure if this has got anything to do with that.

I'd like to find out if my system can take a certain load, number of PHP requests per unit of time. How would one go about this?
I'm about to make a change on Digital Camera Buying Guide, Photography Articles and Reviews | NeoCamera.com that would make all pages pass through PHP with personalized information which will prevent me from setting the cache-validity any significant amount of time (currently it is 1 hour). To handle the current load it needs to process 500 PHP requests per minute but I would like to make sure my system can handle twice the load. It is a Phenom II X4 with 8GB RAM running OpenSUSE 11.2.

Ever since 11.3 Open Office was performing "badly" to say the least. It loaded slow, with a few documents open "save-as" and selecting a different folder took up to a minute and so on. Anyway I had the suspicion that there maybe not enough memory allocated. Nothing within the OO settings worked.
Then I looked into yast=>/etc/sysconfig=>System=>Limits...
found "HARDLOCKLIMIT" set to "@256"
changed to "@512"......OK finished.
Ran a test with 10 documents open
a) Startup was much faster
b) Saveas instantly
c) PDF instantly
d) Selecting new folder instantly
Preliminary conclusion : Java(sun) and OO needs more memory

I was using centos for my business applications and now I am trying to work only with opensuse and install my other oprerating systems in it. I was always using vmware , but I decided to try another virtualization technologies other than vmware for testing , I searched the internet and found many other like virtualbox , kvm , xen. I concluded from my search that xen and kvm will be the faster type , I decided to test them, I choose xen, it is better than kvm. I installed opensuse 11.4 and installed xen hypervisor deployed two VMs windows xp and centos 4.8 , they are runing quite good but I have some questions:
1 : Isn't there anyway to improve graphics performance in xen guest , or change the video card memory or type ?
2 : Isn't there any way to copy and paste between the host and guest ?
3 : Isn't there any free application like vmware tools or virtualbox guest tools for xen ?
4 : I use these VMs to install some applications for my geophysics work which requires good graphic performance in the vm , also I don't them to be sluggish sometimes , which is better for that vmware or xen ?

I'm new to openSUSE and my computer is quite slow although my computer isn't that bad. I opened up ksysguard and it appears that my CPU is the bottleneck. My CPU usage is usually 100%, then after a few seconds, it goes down to 20-60% and then it goes back up to 100% after another few seconds. It says I have 141 processes running (I don't know if that's normal or not).
My Specs are:
CPU: AMD Duron (tm) processor 1.8GHz
Graphics Card: NVIDIA GeForce 6200
Memory: 2GB RAM
I'm using KDE.

Are there any tools available in openSUSE for evaluating cpu/processor performance. My processor/cpu is under warranty til end of October, will like to know whether I need to get new one or i am good. I am looking for something that can log an event and report. Have tried stress and crashme but they dont show any results.

I have an 11.2 laptop and thought it was time to upgrade to 11.4. I downloaded the 11.4 X86-64 live cd and thought that I would check how it ran on my 11.3 desktop. This is a core i5 760 with an Nvidia GT240 graphics card and 4GB of DDR3 ram. The 11.4 live system shows the nouveau driver. The graphics performance is terrible. In particular windows are very very slow to resize and often don't resize properly. There are also some artifacts in some graphics. I eventually downloaded Flash which did seem to work moderately well, especially in full screen mode. The screen resolution is 1920x1080. I have never seen a windowing system work so slowly
While I always use the Nvidia proprietary driver, I don't know how I can test it via a live CD. The Nvidia driver in the repository is the 270 version and I think that I have seen reports of severe problems with the 270 version so that needs to be tested too. I always install the nvidia driver the really easy way via yast
Has anyone any idea why the KDE Live graphics are so slow? I will not go anywhere near 11.4 unless the graphics system is very much faster. Is there any way to test the nvidia proprietary graphics driver without installing 11.4?

I have an ATI Radeon HD4850, and I use the proprietary ATI fglrx drivers. However, when I try and full screen a flash video, my performance hits the fan. It's choppy, and even takes 5+ seconds to even get me back out of full screen to "recover". I mean, in windows I can play full screen 1920x1200 games on decent settings. So I doubt flash is too much to ask. I'm aware that ATI is basically the -worst- when it comes to linux drivers (Hence why my next card will be an Nvidia card. ) but I was wondering if there's anyway to fix this until that (glorious) day comes. As far as versions go, I use the latest Firefox, my flash plugin is:
Code:
File: libflashplayer.so
Version:
Shockwave Flash 10.0 r42
and my fglrx is
Code:
matt@matt:~> fglrxinfo
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 4800 Series
OpenGL version string: 3.2.9551 Compatibility Profile Context

I have a Dell Precision M6400 laptop with an Intel Core2 Duo 2.8 GHz processor.I have set Power Management to performance when on AC power and have also written a script that calls cpufreq-set to set the lower and upper limits to 2.80 GHz (cpufreq-info output below).However, sometimes when doing some heavy work the frequency suddenly gets reduced to 1.60 GHz on both cores and I cannot set them back to 2.80 GHz using the script (cpufreq-set says errors occurred). Performance is then totally gone and I have to reboot. The same script then works fine after a reboot.What is setting the lower limit back down to 1.60 GHz even though I set it to 2.80 GHz using my script? How can I stop/configure this or prevent it from happening?

I have installed several different distro's over the last coupled of weeks and have finally as intended come back to 11.4. Last time I installed it my pc was fitted with an older nvidia card and I installed a newer 200 series and got it to work with X11 using the nvidia driver. This time I did the install with the new card in and things haven't gone the same way. I have finished up with the os drivers on my system, nouveau and "swrast (No 3D Acceleration) (7.10)". Performance wise it's way way behind the nvidia driver.
Glxgears for instance runs at under 1/2 the speed even at a lower resolution. I suppose I could still configure to suite my monitor but given that difference in performance would you? I have done what I can easily do with repositories but no signs of nvidia drivers. I can download one as I did last time but from what I have read previously the above drivers may mean that I have to recompile the kernel. A simpler solution might be to re install with my old card in. Can't say I'm too keen on either option. Some distro or the other had a driver helper and installed the nvidia one perfectly.

operating System: Opensuse version 11.3 (x86_64) Nvidia Driver Version: 256.35 I have been getting sluggish performance while playing games recently as a normal user, although when I switch to a superuser I get great performance.
I have ran the command Glxinfo as a normal user and I get the following output. name of display: :0.0 NVIDIA: - Anonymous - TzhDEdV5 - Pastebin.com When run as a superuser I get the following output. name of display: :0.0 display - Anonymous - 4nb3pDJH - Pastebin.com I have noticed a major difference in output is that as a normal user Direct Rendering is not enabled, though as soon as I log into the super user there is no such error message.
Is there a way that I can enable Direct Rendering as a normal user? I believe that this may be part of the issue.

I'm wondering if anybody could explain this phenomenon to me. I have just had a box stop on me, probably power supply failure. It was running with an AMD 2GHz cpu, 32 bit, 2GB memory. The Radeon card was using the x-org "radeon" driver and giving upper 3000 to lower 4000 fps according to glxgears.
I have transfered both the radeon card and the hard disc from the dead box and loaded them onto a different one. The new one is running with an intel pentium 4 running at 1.7GHz, 32 bit, 1GB of memory. On this box glxgears reports only upper 600 to lower 700 fps.
OK. It's a slightly less powerful cpu but by only 300 MHz. "top" shows glxgears using 72% of the cpu and the cpu shows that it's loaded at 60%. There is still free real memory and the usage figures for it do not change during the running of glxgears. I am really puzzled as to why there is a fivefold plus drop off in performance.
I mean, the software etc is the same as on the old box - it's using the same disc after all. I can only think that there is something else that is getting in the way but what?

I am fairly new to opensuse/linux and have been running into a very intermittent I/O issue that I can not seem to pinpoint the source of. Just about any program that deals with any significant IO will fall into uninterruptable sleep. For example here are two instances of dd. The first time it hung in uninterruptable sleep and the second it was completely fine and performed as expected.
[Code]....
Monitoring disk I/O with iotop indicates normal performance for most of the time then all the sudden the read/write drops from ~60-80MB/s to 1-2MB/s. This happens for just about any program I run. It is not easily repeatable since it seems to randomly happen. My limited knowledge led me to believe that it could be a symptom of the old SLED 10 OS that i was running so I upgraded to openSUSE 11.4 earlier this week with no change. I have changed the journaling to ordered and the I/O scheduler to deadline as well as cfq to no avail.

I have installed OpenSuse 11.3 32 Bit in a virtual machine on an older computer on a Windows XP host and on a new computer with AMD Phenom II X4 965 processor.
With sysbench I tested the performance of mutex and on the new computer it is 3 - 4 times slower than on the virtual machine. Other performance tests with sysbench for CPU, memory and threads are faster on new computer like expected. I tested this, because I have a slower performance of table creation in MySql tested with sql-bench, where creation of 10000 tables lasts 45 seconds on the virtual machine but over 400 seconds on the new computer.
I have tested with kernel-desktop and kernel-default but there are not large differences. File creation was tested with bonnie++ and is on newer computer faster as expected.
My questions are:
- Why is the mutex handling on the multi core CPU slower than in the virtual machine and how to speed up this?
- Or is there another reason why table creation of MySql is so much slower on multi core CPU?

I went back to Suse 11.2, it comes with the 'nv' driver for my NVIDIA Quadro2 Pro (64 MB) and I'm getting some slow performance on browser display and sometimes video playing. Not always, I recently saw a 2 hr long movie on Blue Ray resolution, so the problem is not hardware, it's software. I saw several links here on how to install other drivers and a 1-click install link on this page but my question is, since this is an old card... which driver is the best for this card ?
