Weird problem, help!
I have a few servers that are:
AMD Athlon XP 1900+
1gb sd ram
they have been running great.
i'll untar a 300mb file, and it'll go fast, and be done within a few seconds.
Then i have another one, that's AMD xp 2000+, 1gb DDR ram. It also has been running great, a b it faster than the xp 1900+
Recently I bought a server that had the following specs:
AMD Athlon XP 2200+ (1.8ghz)
1gb DDR ram
40gb hard drive
my host just got it online last night, and emailed me the info.
so today, i'm downloading proftpd, apache, php, installing my own stuff, ya konw, everything is going fine. apache compield fast, everything went smooth
Then, i downloaded a 300mb file to the server, and ran
tar xzf stock.tar.gz &
because i didnt want to sit through and read what it was unzipping (i knew what it was unzipping)
so while it was in the Backround, i went to go install proftpd, but i noticed the box being REALLY sluggish.
I'd press enter, and it wouldnt do it until like 2 secs later.
Or i'd do wget ftp://balh/blah/blah/proftpd.tar.gz
and it'd be REALLY slow, and i'm not talking network wise. you could tell this was a problem w/ the machine.
i went to go login the box twice, and boy was it slow.
took forever just to get to the root prompt (Again, felt like it was a machine prob)
i ran 'w' and saw the load average being 4. something (i think 4.40)
i was thinking WOW, 4.40 load just to untar a 300mb file ??
Keep in mind, ive untarred this SAME 300mb file on my other xp servers, and the load was alwyas under 1.00 (more like 0.63)
i just could not understnad why the box was behaving this way. it was almost as if it was just struggling..
so i ran killall -9 tar gzip
manually unzipped it
tar xzvf stock.tar.gz
then i checked the other window (where i was logged in twice)
and again, the load sky rocketed
i was puzzled.
i ran top, and these are some of the things i saw (i tried to capture it before it disappeared)
Can you believe that?? I have untarred huge files on my other xp's, and watched top while i did it, and kswap never uses 99% cpu??
neither does kjournald
something is seroiusly wrong. NONE of my xp's behave like this one does
Does anyone have any idea why this is happening? Any info would be appreciated!

Hmmmm... Looks like DMA was off. Usually it's on by default, I guess for some reason it wasn't. Well anyhow, i ran hdparm -d1 /dev/hda
and now the problems are gone.
Well for anyone who took the time to read the thread, thanks, and sorry i wasted your time!
Mod please delete this thread, or close it.
