Re: System slow down

I have done a top. Nothing is running.

I used the memtester from http://www.qcc.ca/~charlesc/software/memtester/ to test the memory to see if the memory was failing or a card was improperly installed.

The initial login screen takes five minutes or more to appear.

I have a Dell station, 665 MHz, 256Kb Cache, 256 Kb ram, that is unuseable because it is too slow. The system used to be fairly quick; we had been using it as a web server. Now there is a delay in any graphics display, "ps", "vi", "man", and "rpm" process. I would appreciate any suggestions of where I should look for the problem.

We had two disks on the system. The system disk is a Maxtor 52049U4; the auxillary disk is a WDC WD800BB-00CAA1.

I repartitioned the Maxtor disk and gave all the system partitions plenty of space:

/dev/hda6 280005 102347 163202 39% /
/dev/hda1 77750 14180 59556 20% /boot
/dev/hda8 7036620 32828 6646348 1% /home
none 127064 0 127064 0% /dev/shm
/dev/hda7 256667 8250 235165 4% /tmp
/dev/hda2 8926100 1157000 7315668 14% /usr
/dev/hda5 1019864 43548 924508 5% /var


swapon -s
Filename Type Size Used Priority
/dev/hda3 partition 2048276 0 -1


I installed RedHat 8.0 as a new system. I have since upgraded the system to 2.4.18-24.8.0. It is still sloooow.

One at a time, I have taken out the second disk, pulled out the ethernet connection, and stopped the X display on the system. I normally use GNOME.

vmstat

procs memory swap io system cpu

where in looks suspicious. The count was just as high when I rebooted without an ethernet connection.

Looking in /proc/stat
