Run in a terminal window the command dmesg
and look for suspicious warning messages.
Also look in /var/log/messages (might need to be root user for
that due to the file permissions). Most of the messages
are informative but some flag problems. I'd especially
look for things that time out.
also run this command:
does the resulting string have "SMP" in it? You installed the i386 kernel
but I want to be sure it was the i386 SMP kernel since it's a 930D chip.
Of course even the plain uni-processor kernel would be fast on your
The only other thing I see that's odd about your system is the
very large amount of ram, you wrote "4Mbit" but I'm sure you
really meant 4GB since it's impossible to put 4Mbit of ram in
a modern PC. There are some negative effects that happen
with linux at very high ram amounts when you use the default
precompiled kernel. You can reduce those by compiling your
own kernel and when you are doing the make xconfig step
set the flags like this:
then compile the kernel
As an aside, this is one of the advantages of using the AMD64 EMT64
extensions kernels, you don't have to even think about this ram stuff,
it's just plain flat model no matter what amount you have (well,
that's effectively true, the limit is so high you'd never install that much)
I don't like compiling my own, I tend to forget or not know about
some setting and then something breaks. (last time I broke automounting)
If you want to diagnose if the memory size is an issue, you can
just fool linux into thinking there's only 1GB of ram, reboot, and
see if it's faster. Become root and put in the /boot/grub/grub.conf
file for the kernel you use:
Like in my case it would look like:
title Fedora Core (2.6.16-1.2122_FC5smp)
kernel /vmlinuz-2.6.16-1.2122_FC5smp mem=1G ro root=LABEL=/
save that and reboot and run with that kernel and see if it's
faster. Make sure you remember to remove the "mem=1G" later
after the test.
Other than this I don't get what's wrong, even if it's a memory issue
that kernel buffering is usually pretty small effect, you'd noticed it
if you were doing something ram heavy like Oracle but I doubt
a home user would notice.
