Does disabling Hyperthreading (at BIOS setup control program) help?

With 4G I'd install the x86_64 version. Not that I think that PAE is the
reason for this slow behaviour (last reporter who had that somewhere on
bugs.centos.org had bad RAM), but ...

additional useful info might be ...

# dmesg
# lspci
#vmstat 5 5
# iostat -x 5 5

the last 2 will take about 30 seconds each to run (oh, iostat is part of 
package `sysstat` which may not be installed by default, `yum install 
sysstat`)

and if the dmesg output doesn't start with
Linux version 2.6.18-92.1.6.el5 (mockbuild at builder16.centos.org) (gcc 
version 4.1.2 20071124 (Red Hat 4.1.2-42)) #1 SMP Wed Jun 25 1
3:49:24 EDT 2008

(or similar) that means the dmesg buffer likely overflowed, so cat 
/var/log/dmesg to get the snapshot output of it right after the system 
booted

[CentOS] CentOS5 running very slowly on a core 2 duo with 4 GB RAM

Hi, I've installed CentOS5.2 on an INTEL Core 2 Duo (Intel(R) Core(TM)2
Duo CPU     E6550  @ 2.33GHz), 4 GB RAM (MemTotal:      4072176 kB) and
my system gets sevarel minutes to startup, specially on udev daemon.
Once the system is UP, every command I run gets 100% CPU and every is
very slowly at the point yum -y update never ends. The system installed
by default this kernel 2.6.18-53.el5PAE. I would like to know what's
wrong with my server. Do I have to install another kernel? Can you help
me?

with 8GB of RAM and I got better performance w/ PAE than I did with 
x86_64, but YMMV depending on usage of the system...

Israel, have you tried running memtest86 just to rule out a memory 
error? Also, when you installed, did you let the installer check your media?

Well, I ran memtest86 and I got no errors....I installed this kernel
2.6.18-92.1.10.el5 and everything was very fast BUT, it only recognize
3GB RAM. :-(  I installed CentOS5.2 64 x86_64 bits and I got the same
slow performance.. On x86_64 I installed the latest kernel and nothing..
:-(
 
Regards..Israel

[CentOS] CentOS5 running very slowly on a core 2 duo with 4 GB RAM

If your disk controllers aren't properly recognized, it might help
booting with

hda=noprobe hdc=noprobe

You can test this by running "hdparm -t -T" on your disk with and
without these boot options.

This has helped me on some systems.
