Basically I'm wondering if there is any way to lighten Gnome and Ubuntu I would like to keep Gnome if possible. I am a pretty experienced linux (or for you hardcore GNU fans GNU/Linux) user having used it for almost 4 years and I just built my Arch system but have found that alot of the functionality that I've come to love about ubuntu isn't in the default Gnome package but that Ubuntu's Gnome is heavily modified so I want to switch back but do to my lack of modern hardware I can't run Ubuntu as smoothly as I want.
Below is my current hardware.
Code:
Intel Pentium III 733mhz
512mb of ram
8gb Hard Drive
and a Dvd Drive
Nvidia Geforce 6600 265mb pci gpu
100 watt power supply
I am also a Developer so I know I can compile the Kernel my self and remove some not needed junk and optimize it. But I was wondering are there some Highly intensive processes that don't really need to be running? The only thing I would be using Ubuntu for is Web Browsing, Coding, Gimp, Text Processing and probably Music; thats really all I need I don't do much else besides that.
tl;dr:
Basically all I'm trying to do is lighten Ubuntu and Gnome without putting 3 days worth of work into it.
I have an older PC running Ubuntu 10.04, and the system is slow, especially with Firefox running. I recently upgraded to 2 gig memory, but it didn't help. I have plenty of space on my hard-drive, using only 30 gig of 80 gig. My CPU is Intel Celeron 2.40GHz. I have broadband, and the speed seems good. What are the system requirements for Ubuntu 10.04? Any tips for speeding performance, esp on Firefox? I used to do a defrag when I had Windows; is there any need to do that on Ubuntu also?

I am running the newest linux (ubunbtu 11.04) on an old laptop (2.3 Ghz celeron, 760 mb ram, bios is the latest version). I don't expect it to perform well, it's not a fast processor.But.....it performs so poorly with linux...and I am beginning to wonder whether the machine is broken or malfunctioning. The processor utilization seems high at all times, but I am not sure what is normal/typical.Which of the many benchmark software packages should I use in order to quantify it's performance (or lack there of)? Are there web resources that will list benchmark values of various machines, so I can determine if my punch box is broken or whether it's just slightly slower than other similar machines?
View 3 Replies View RelatedI 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.

Wired performance is super, wireless performance however is very bad on Linux. On "Windows 7" (dual-boot, which I never use, only in these cases to sort out problems...) wifi performance is slightly better. My smartphone's visual wifi-analyzer (I couldn't find a Linux equivalent...) showed good signal strength (aournd -50db a 4 m distance from router) an little-to-no interference from neighboring channels.

Is there any way of improving performance with the GTX 470 using Wine software with Debian Squeeze?
Installed version of Wine is 1.3.6 tested with different versions of nVidia drivers including the latest one, still VERY slow performance and many quality settings are in red. Setting WoW to use OpenGL improved the performance, but deactivated many quality settings in red, unfortunately. Looks to me as it's using lower features than OpenGL 2.0?? So what's up with that? GTX 470 supports OpenGL 4.1 so I suspect it's an limitation in Wine software, can anyone confirm this?
Default kernel 2.6.32 is used in all of this. The computer is an Intel Quad at 2.4ghz + 4 GB DDR 2 or DDR 3 memory.
Does anybody know more tips and tricks to increase visual performance besides these?:

View 2 Replies View RelatedI just have a few questions about LVM and RAIDs. It seems they are basically the same thing. Is this correct? I can add two drives together on both of them and it appears as a larger drive, along with other setups like raid1 and raid5, etc.. And is there a difference in performance between them?
And my second question.. I know one is stripped and one is not, but is the performance between a raid1 and a raid0 the same? I've been told that raid1 is faster than raid0 because the data is written twice.. and therefore can be read from two different disks which equals faster read speed, but slower write speed since it writes to the two.
II installed flashplayer by every different method I can so far, and all of them have the same problem. This problem presents itself, for example, while playing a video on ...... As the video loads, flashplayer is fine, but as soon as it starts playing, the browser tab begins to run at roughly 1 frame per 10 seconds. When I turn the browser priority to maximum in System Monitor, it improves slightly, going to about 1 frame per second. The strange part is, my CPU and memory usage barely spike at all, to less than 30%. This happens regardless of browser (have tried iceweisel and chrome). It happens with hardware acceleration on, and off. I have tried installing flashplayer from the tar.gz on the adobe website, from the repository (all three packages), and manually placing the plugin in the browser myself. The issue presents itself the same every time.
My system specs are: 1.83GHz duel core intel centrino processor, 3GB RAM, ATI Mobility Radeon HD 2600. Nothing fancy, but flash player performs as flawlessly as flashplayer can under windows (and also performed well in my previous Ubuntu 10.04LL install).
I have 2 ASUS Boxes (one with 8GB, one with 4GB) When both mtus are set at 7200, using scp to copy a 56MB file takes 2:06. If I reduce either mtu to 1500, the speed is 2 seconds. I'm wondering if this is some kind of kernel bug or driver bug or what. For the moment, I've lowered the mtu to 1500 to get the performance out of the machines, but find it interesting that what should make it faster is actually slowing down. Where should I post this to get it looked at? Is anyone else seeing it.I see a similar performance issue with smbclient too.

I have tried Lenny, Squeeze and Sid, I have compiled the intel driver (and Mesa3D) from git and got it working (I am sure its working because its given me a slight boost), I ahve also tried building the latest stable (and RC2) kernel.If I install ubuntu 9.10 I get pretty decent 3D performance, its not ground breaking, but hey its an intel chipset so I am not expecting to kick the latest nvidia / ati card's backside.I really dont want to use ubuntu, I find it unstable when compaired to debian, but I also want to be able to play the odd game when I am bored, and at the moment I just cant do that under debian
I have an ATI Radeon x1300 graphic card on an Intel platform.Since the last reinstall my Debian Squeeze system shows very poor performance in glxgears,only 80-90 FPS. Last time I had a problem the kms setting in the kernel. I disabled the modding setting in GRUB and then glxgears showed about 900-1300 FPS. Now,the problem is back, even though I made the same setting in the boot loader.
View 14 Replies View RelatedMy last laptop was replaced (I gave it to my step-dad, his laptop broke and I bought myself a new one).
I am running Squeeze (as I was on my other laptop) and everything is fine except for the games. On my other laptop games like OpenArena and Warzone 2100 ran perfectly fine, but on this laptop, they are impossible to play. The game will open, but everything is so slow and choppy that it takes a couple of minutes to even move the cursor to the exit game buttons.
My current laptop is an HP ProBook4525s with the current specs:
AMD Athlon Dual-Core P340 2.2 GHz processor
2GB DDR3 RAM
ATI Mobility Radeon HD 4250 Graphics Card
I'm not sure what other information to put here, I've tried searching how to fix this and most people say to lower the resolution and details for the games but that doesn't work, heck, even Tux Kart is too slow to play!
When I installed squeeze I was informed that I didn't have the rtl8168d-2.fw firmware for my laptop, I'm not sure if that helps here at all (can't seem to find what it is for, the only things that google gives me are very technical with fixes that involve re-compiling the kernel).
I've got 4 identical 1 TB drives and would like to use them in a software RAID configuration on my home server. I'm running Debian Linux using 'mdadm' utility to manage the software RAID. I don't know how much I've read is fact or dated or even false so I decided I would ask here to get help from people who know more about this than I do. This is essentially just a file server machine to store all my data so being that I've got four identical SATA hard drives, I was thinking about doing RAID level 5. I guess I'll start here and ask if that is the recommended level of RAID. I think RAID level 5 will be fine for my general server usage. My second issue is partitioning the four individual drives to get maximum performance / space from them. Basically just asking here how would you or you recommend I partition the drives? I was thinking about doing three seperate partitions per drive:
/dev/sda1 = 4 GB (swap)/dev/sda2 = 1 GB (/boot)/dev/sda3 = 995 GB (/Now from that partition schema above, obviously all the types will be 'fd' for RAID and the partition for /boot is going to be bootable. My confusion is that I read Grub doesn't support booting from RAID 5 since Grub can't handle disk assembly. If /dev/sdx2 (sda2, sdb2, sdc2, sdd2) are partitioned for /boot (bootable), how would you guys configure this RAID to match up equally? I don't think I do a RAID level 1 on 4 identical partitions, right?
i had recently loaded squeeze and had an issue with the 2d performance.i.e when being prompted for the root password, the shading slowly draws down the screen several times before stopping at the final darker shade. i then added the linux-firmware-nonfree package. all worked extremely well, even compiz, but i don't really care about compiz. i just loaded it to see how it performed. i then distro-hopped a bit and when i came back to squeeze the first thing i did was add the package, but the video is acting like i haven't added the package. i've searched for an answer, but have not found anything recent to indicate if xorg was upgraded or what.stable lenny works fine, but i'd rather have the nice console fonts when not in x and more up to date apps like gimp and xsane in squeeze.
View 5 Replies View RelatedI have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?
This is my 2nd attempt at installing Debian since 5.0 several months back but I am determined to get it running this time.Install of 64bit Squeeze went well, installed the ati proprietary drivers directly from ati which resulted in horrrible performance.Uninstalled that and followed to the T. At the "aticonfig --initial" part I got the message "No supported devices detected" soI went ahead and entered the config manually. Now on normal boot I get a black screen and I can't seem to boot into Recovery mode as it hangs at Tray or ANSI.

View 0 Replies View RelatedI have been trying to install a command line Debian Squeeze system on n Eee PC 701., but have run into a number of problems:
1) All install info I can find assumes that the person wants to install a GUI system of some sort.
2) The Eee PC has a unique 2 MB. partition that needs to be preserved, so no guided install.
3) The Eee PC has an SSD instead of an HD. Most postings I have seen recommend an install without a swap partition, but the install (both live and text) seems to choke and despite a fresh formatting of the existing partition, claims to be overwriting existing files.
4) I can understand from the wiki that the Eee PC wireless driver (Atheros) should be included in Squeeze, but when the wireless connection and password is added, the installer claims that the password is not correct, despite me having checked it a number of times.
I hope someone can help me out. I just want to use the Eee PC for low resource stuff done on the cli like using a text based web browser to access the net through a wireless router and to hook it up to an external USB HD and to my stereo, to play my music collection.
