RH9 is very slow
 

Hello everyone,

I just recently installed Red Hat 9 on my computer. But it is much, much slower thafile:///usr/share/doc/HTML/index.htmln any OS i have had on here.

I have an el cheapo computer i got off the tube, nothing very good in my box, like 800 something MHz AMD Duron and such.

I will appreciate all the help i can get.

Thanks,
Gorq

redhat 9.0 is slower than other distros for some reason..try downgrading it to redhat 8.0 or something. I am running mandrake 9.1 and its pretty good...hope it helps

hmm... try shutting down unneeded services in Red Hat 9.... try to post the services that are running in your system....

I put redhat 9 in last night. I agree, it does run very slow. :(
Mandrake 9.1 is faster :)

hmmm... i dont think so. My comp is 400MHz intel P2. It is working very good.

I went from RedHat 7.3 to 9.0 and performance seems identical.

I find /etc/cron.daily/slocate.cron to be particularly annoying. Disable it like this:

chmod a-x /etc/cron.daily/slocate.cron


You can do "/sbin/chkconfig --list | grep on" to see all the services that are enabled

I've found excessive swap activity to be a problem.

remove excess startup options using setup command and it should work fine.i am using it and boot up time is much faster than rh8

I also have several system running both RH8 and RH9 and don't really see any difference in the porformance.

I agree with ending processes, and maybe cutting size. I one time did an install and selected everything. Bad idea, it was unberable. Taking a full minute to load a web browser. I have had good expiernece with it before. I found it ran about the same speed as mandrake 9.1 without all of software.

One other possibility is broken DNS setup. For GNOME apps at any rate, this can cause Bonobo Activation to hang waiting for a resolution timeout, causing application startup time to go +30seconds

hmm... there seems to be alot of people complaining about Red Hat 9 being very slow.....

Hi there

i have serveral Redhat 9 machines running. First a laptop with Celeron 600 processor and probably a slow harddrive. This one is indeed a bit slow.. but the PentiumIII 800 runs like the devil. At home i have a athlon 1,3Ghz which runs quiet well to, BUT!!! i just installed a machine with a athlon 1Ghz and probably not such a fast harddrive, and its sooooooo slow. Its not workable. I can't seem to find what the problem is. Someone in another group said something about Automount being on, and when turning it off, it was over... well, im gonna try that, but if anyone has some different tips, PLEEEAAASE DO!!.. im trying to convince some people to work with Linux, and this way its not gonna happen.. heheheh...

:confused:

I have notebook that was very slow with 128mb ram and now with 256mb it runs much better. The harddrive doesn't get bogged down with virtual memory.

My older computer is a 266 MHz Pentium II computer with 192 Mb of RAM. At one time I had both RH 9 and RH 8 installed on it. Both ran well on that computer although the RH 9 took longer to boot up than RH 8. Once booted up both responded quickly. On my old 266 MHz computer either version of Red Hat would boot up much more quickly than Windows does on my newer 2 GHz computer. Win 2K takes about 10 times as long to boot on the 2 GHz computer as RH 8 does on my only 266 MHz computer. Win ME is also on the new 2 GHz computer and takes only about twice as long to boot up as RH 8 on the old 266 MHz PII computer.

I have found that Open Office is slow to load on wither computer and that it does not seem to matter what version of Linux I am using. Open Office does great once it is loaded but is very slow to load. Because of that, on my newer computer I switched to using the Textmaker word processor instead. It is an excellent full featured word processor that opens up in about 1 or 2 seconds. It is not free however. I have not tried using it on the old comuter.

The RH 9 box recommends having 192 Mb of RAM, how much do you have?

hey there...

this computer im talking about is a 1Ghz Athlon. It has a 19Gb Hardisk. I have been trying to use HDParm to get it running as it should, but i cant seem to get higher then 20Mb/sec. That really strange because it should be at least twice as high i guess... here is a dump from hdparm:

readahead = 8 (on)
geometry = 2491/255/63, sectors = 40021632, start = 0

Its now exactly 20Mb, but is with different parameters is only going down... :(

The IDE controller is a "VIA Technologies|VT82C586/B/686A/B PIPC Bus Master IDE"

I guess that more memory should fix some of the problems, but the drive will still be performing low i guess... Im getting despirate :)...

My own computer with redhat 9 runs like the devil!!! (and im trying to confince someone to start using linux... not such a great time for that i guess, hehehe)

ow, i saw that i forgot something

if i use hdparm with -c 1 or -c 3 i get a performance of 15Mb ???!!!


HEEEELLP MEEEEE.. :)

How would I go about shutting down uneccesary programs running in the background before they startup? I just switched from mandrake to red hat yesterday so I'm not familiar with this new menu. Also I'm a linux noob to begin with so that doesn' help :)

If you want a gui you can use /usr/bin/redhat-config-services.

There's a nice command line tool called /sbin/chkconfig, see "man chkconfig" for details. For example, you can do "/sbin/chkconfig --list | grep on" to see all the services that are enabled. "/sbin/chkconfig --level 345 xinetd off" will stop xinetd from starting. If xinetd is currently running, you can stop it with "/etc/rc.d/init.d/xinetd stop" or "/sbin/service xinetd stop".

My system slows down when there is heavy disk io. I heard that the preemption is supposed to fix that kind of thing (prior to 2.6 you would have to patch your kernel). How much bandwidth are you talking about?

I'm talking 40/k outta my 83k max. Why would I want to stop xinetd though? Is this a useless daemon? From the man pages it seams like it would be critical to running anything having to do with internet process. Or am I mistaken?

hi there...

i have been messing around with that machine i mentioned. I still cant get higher speeds on the harddisk, but it seems to be a 5400 rpm disk. So maybe its the max. I installing the NVidia drivers from NVidia itself, and i disabled some things in XFconfig86... when i started X as root i noticed a lot more speed then before.. so i thought it might had to do with hosts & dns resolving.. i tested some things and messed around with the hostname. Then i deleted the original kde account and logged in again. It was allot faster after that. Still not what i should be.. he seems to have some memory problem and uses the disk way to much while swapping... first im gonna try to put some more memory in the machine and see what will happen..

p.

My cable provider lets me download at 384 kilbytes/second and my system doesn't even notice.

I was only using xinetd as an example service. Many network daemons use it (telnet, ftp, etc...).

Is it possible that a video card driver update (running a radeon 9100) as a possible solution?

My RH 9 is also slow. Slower than Windows XP Pro. A driver update for Windows XP Pro solved the problem. However, I'm still a super newbie when it comes to Linux.

Yup , me too Redhat 9 is slow,

I have 392 mb of ram and i got only 40 mb free , no window open no programs.

Redhat eats totaly my ram :(

If you're feeling brave, compile and install a stock kernel.org 2.4.20 kernel, I have found this *dramatically* improves performance. Others have found this too. It seems that Red Hat screwed up the kernel in this release big time.

That's crazy. I'm running KDE, mozilla, Konsole, and lots of services, and here's what I get from the "free" command:
that's 208280 kilobytes used.

BTW, I compiled my own stock 2.4.20 kernel (actually it's patched for udf write on cdrw) but I didn't notice performance problems before (or after) that.

Yes, Redhat9 might be slower on your machine, but could you imagine running WindowsXP on a 266Mhz, PII, with 192MB ram!! You can't! Eventually, you will need to upgrade your hardware. Redhat9 was released March, 2003. The PentiumII was released April, 1997. If your machine is running too slow, I would suggest not upgrading your OS to the latest and greatest. I am running Redhat7 on a PentiumIII, 400Mhz with no issues.

To run REdhat 9 correctly i recommend 1 gig of ram!!!

hmmm i was running red hat 8 b4 and only had 3 gigs, 300 mhz machine. After i bought a new 30 gig harddrive for my server, i installed red hat 9 (everything). Im running an apache webserver and ftp and i see no difference in running speed from 8 to 9.
Of course im buying a new mobo and athlon +2000 for it soon, so i should have no problems at all.

More is ram is always better, but many people can get away with much less. Earlier in this thread somebody said 192 mb was sufficient for them, and I have a notebook with 256 mb that is also sufficient.

I am running Redhat 9 on p4 2000hz with 512MB RAM. Its running faster than Mandrke 9.1...

Yep, Open Office opens little slowly. M$ Office rocks!!! Sorry to say this, but its best to admit facts.

I have Pentium 4 1.7 Ghz with 1024 Mt of RAM.

I have just installed RH9.0 and have RH8.0 on another system of similar configuration... Both are responding at same speed...
