To some doc's or how-to's that will show me the best recommended settings for optimum performance for both apache and php configurations?
View 1 RepliesI'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.
How do i upload files using apache configurations. ho do i do that. i am using centos.
because my client wants upload files through httpd.
In Short: I want something that will show me which files and associated requested URLs are causing the highest load on our web server.
Verbose: We already monitor our Apache web server using Cacti, Nagios, and of course traditional nix commands, but I am looking for something specifically to take an Apache process ID and tie that to a users request for a specific file and URL. The great thing about something like this is that it would be able to show me the worse performing PHP files. Special bonus if it can store this data over time for reports.
I have been googling around for something like this but can't seem to find it. Bonus if it exists in Cacti or Nagios already and I'm just to blind. I started writing my own PERL script to do this, but have limited time to devote to this at work so if a solution already exists I'm game, else I'll just have to write it myself. I'm also worried about my own scripted solution in that it won't get it write because it will be leveraging the output of a specialzed apache log that records the PID and then doing a look up with ps aux looking for that PID.
i dont have much of command line experience with linux.can i setup opensuse server in such a way that i do all my configurations in gui mode and then switch the server to no gui mode as to free up resources.

View 8 Replies View RelatedThis is a general technical question about Symmetric Multiprocessing in relation to the Intel Core i7. (Actually, it's more about Hyperthreading than i7.) My understanding is that Symmetric Multiprocessing means that the operating system treats all processors as identical, and therefore it can assign a new thread to any free processor.
And that i7 appears to the OS as 8 processors, 0 thru 7. But from a performance perspective, the 8 processors are not identical, because each core has 1 execution engine plus the ability to store the state of 2 threads. This is, as far as I understand it, the essence of Intel's Hyperthreading. So each execution engine can quickly switch between 2 threads without bothering the OS, but only one thread at a time actually executes.
Suppose, for example, all processors are idle and the OS assigns one thread to processor 0, then has a second thread to assign. Since all free processors are considered identical, the OS could assign the second thread to any free processor, say 1. The result would be that both threads are competing for the same execution engine, while the other 3 cores remain idle. Is my understanding of SMP correct?
If so, does linux SMP take full advantage of Intel Hyperthreading (which existed also in earlier Intel processors)? That is, does linux SMP assign threads in such a way that it attempts to choose an idle execution engine? I don't know what algorithm SMP actually uses to choose the processor. For example, it could be the first free processor, or any free processor chosen at random.How about Windows? How does it handle the situation?
Edit: I have also posted this question in linuxforums and phoronix forums. I hope this doesn't count as cross-posting, since those forums are not on this site and they have different readership. If it is indeed cross-posting, please let me know and I will avoid doing it in future.
Greetings ubuntu members. I have recently been trying to install ubuntu 11.04 on my old computer and I installed ubuntu with no problems but everytime it takes me to grub, the monitor will turn black in 2-3 mins with a message saying Not Optimum mode 12080 x 1024. I suspect that this maybe a video card problem? I have a Radeon 9250 video card.

View 5 Replies View RelatedI am having a few websites running in a Reverse Proxy scenario on Ubuntu Server 10.04. The configuration is like this:
Code:
|--------------192.168.1.1
| (site1.abc.com)
|
|--------------192.168.1.2
| (site2.abc.com)

|--------------192.168.1.4

A-------------------|
(reverse proxy server) |
(192.168.1.25) |
|--------------192.168.1.5
| (site5.abc.com)
|
Except one all websites are running properly and being redirected to their respective domains.
Following is the configuration which I used for each site define on server A a vhost file which contains following
Code:
# ProxyPass / http://<Ip of Server>
# ProxyPassReverse / http://<Ip of Server>
So if I have 5 websites then I have 5 vhost file on the gateway in above diagram A and in each of those file as above root of site is redirected to internal IP. 4 of them are running properly. The fifth website is running on port 8080:/keyword. So in its vhost file on gateway I defined
Code:
# ProxyPass / http://<Ip of Server>:8080/keyword
# ProxyPassReverse / http://<Ip of Server>:8080/keyword
I can see on Lan http://<Ip of Server>:8080/keyword but when from internet I try to see:
http://site5.abc.com
I get redirected to a page is https://site5.abc.com:8443/ and it says
Code:
The webpage at https://site5.abc.com:8443/ might be temporarily down or it may have moved permanently to a new web address. The site5.abc.com has a requirement to be run at port 8080 internally and it is not a Ubuntu server.(Red Hat based server). While rest all are Ubuntu servers including gateway A.
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.
View 7 Replies View RelatedI haul my laptop between two different places and was wondering how I can set up two different configs, being able to load either quickly. I'm running openSUSE 11.2 and use KDE4, but I don't use Knetworkmanager to manage my network, I use ifup (although I don't know too much about that either).
View 7 Replies View RelatedFirst 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.

View 2 Replies View RelatedEver 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 searching a good suse monitoring application. I want to monitor performance(cpu,memory) also process,login to system, I want to run some automatically script when process down, send email.
