Red face Slow GUI in RedHat 9.0


I'm having P4 1.6GHz m/c with 128MB SDRAM, 40GB HDD. dual boot (30GB for WinXP and 10GB for RedHat linux 9.0). Video chipset is SiS650. I've Generic VESA driver automatically detected and installed by RedHat and Video shared memory is 16MB. My problem is that all of my GUI applications are very slow. It takes 50 seconds to launch the OpenOffice writer 1.0 at first time and second time it takes 40 seconds. Mozilla is also taking 30-40 seconds. the SWAP partition is of 256MB. BOOT partition is of 100MB.
I want to know where the problem lies. Is increasing the SWAP partition from 256MB to 1GB works?
what I've to do now?

First of all, you really don't need a partition for /boot to be 100 megs. In most cases this won't ever exceed 10mb, unless you just have dozens of kernels to boot from, etc.

Second, a generic driver for your Sis card could be the culprit. As your messing with resource intensive applications anyways.

Don't add more swap unless its needed. I doubt your swap is getting touched now even. Check your logs, check your free memory, etc.

Kill any uneeded services or apps running, example httpd if your not running a web server, kill it. Any other services you not running, I'd kill those off as well....

RH9 says it should have at least 192MB RAM to run X server

Just for reference.... I use RH9 on an AMD K-6 300 MHz system with 128 MB RAM, 8 MB video, slow hardrive. OOo loads in 20 sec, mozilla in 15 sec. This is with KDE 3.1 and not much performance tweaking (I don't really know how!) Maybe you should check out /sbin/hdparm. It might be that DMA or 32 bit disk write is disabled.

My suggestion would be to change your window manager to FVWM and not using KDE or GNOME since both uses too much memory.

with 128mb i'd suggest using blackbox instead of kde to save loads of memory, but that shouldn't be the cause of the excessive slugishness, though...

is everything working fast on the windows xp partition(s)?

did you try and see if a live linux cd works okay?

does it keep happenning even if you re-install your distro?

it's never to late to try another red hat based distro... something like mandrake or jamd, for example...

adding more swap won't hurt you, but the underlying problem is not your swap space.... it's something else.

i have 128mb of ram with a 850mhz amd duron and everything runs super-smoothly... my swap usually won't get used for more than 32mb or so... 64-128mb if 'm doing A LOT of stuff at once.

http://www.jamd-linux.com/

http://blackboxwm.sourceforge.net/


live cd, good for diagnostics and such:

if you wanna check your hdparm settings (as sb73542 said):

http://www.die.net/doc/linux/man/man8/hdparm.8.html

http://linux.oreillynet.com/pub/a/li...29/hdparm.html

http://www.linuxnetmag.com/en/issue7/m7hdparm1.html


and no, you don't need 192mb to run an x server.

good luck!

128MB ram is only good in linux text mode or win98se.

win32sux's opinion is really helpful.

"128MB ram is only good in linux text mode or win98se."

with all due respect, this just isn't true, it's not fair to tell people they need to go and buy more ram to run some graphics decently...

i've seen blackbox run acceptably on a 486 with 16mb...

i personally have 128mb 850mhz and i run everything i need with no problems... mozilla (with lots of windows and tabs open), gimp, mplayer, games, etc...

the problems begin when you want to run a complete "desktop environment" such as gnome or kde on low ram and low cpu... but that would be more like 48mb and 233mhz, for example...

but considering your decent 1.6ghz and your 128mb, even kde and gnome should run okay if everything is set-up right...

BLACKBOX WILL HAVE A PARTY WITH 128MB AND 1.6GHZ.

use "top" to see what's going on with your swap and memory/cpu usage...

http://www.die.net/doc/linux/man/man1/top.1.html

the problem is NOT your hardware specs.



------------------------------------------

by the way, openoffice DOES take along time to load by nature (of course not the 50 seconds it's taking you)... i think the new version loads faster... everybody who uses openoffice installed via rpm knows that it takes way too long to load. i've heard that if you compile it yourself you can actually notice the speed boost, but i'm not sure. i'm waiting for version 1.1 stable (right now it's 1.1rc4).

Is there some optimizations that have to be set? I ran fluxbox on a k6-2 450 w/128 @ 1024x768 res and it was horribly slow

I had similar issues with an onboard intel 810. I bought a geforce4 for like $50 and disabled the onboard video in the BIOS. this solved all of my problems.

If hardware is not an option than I agree with the suggestion of running a lighter windows manager like window maker.

ok., win32sux. I am wrong.

Thanks for your recomendation, I would try to put a penguin in my sister's PC (P166 with 48MB ram). Would be great if it really work.

to chinmay,
redhat's mozilla 1.2.1 startup slower. I think you should try something light like firebird / opera as well.

Yeah, I don't agree with this as well. I've run plenty of machines with only 128MB of RAM using GNOME and KDE before with no problems...

RAM has nothing to do with his machine being slow now, its most likely what he has already running in which he doesn't need running, and anything else along those lines, etc.

i went to mandrake's hardware compatibility page (good red hat based distro well known for being compatible with LOTS of hardware) and found that there was like only ONE sis card in there... it wasn't your 650... this was kinda weird considering there was like dozens for ati and nvidia and trident and such... so i did a little research on that weirdness and what i found isn't too encouraging..

to sum it up: it looks like sis video support for linux really sucks. apparently the 650 won't even go 3d... i think it can be made to work, but there's a lot of "issues"...

i haven't been able to look into it yet, but here's some links for inspiration (the point of all this being that PERHAPS it's a video chip incompatibility that's screwing your performance)...
