Default OS performance hit

I have been using slackware-current for about 2 months now, and up until
now my system has been running really fast and stable. I am using XFCE and
kernel 2.6.6. but recently i have noticed that applications take longer to
start up than they used to. Over the years ive noticed this issue with
SUSE and when i did a format/reinstall everything ran smooth for a few
more months. Is there anything i can do without formating my partition to
get slackware back up to the speed it used to be?

PC specs:
AMD XP 1.8ghz w/ 1gig memmory

Thanks
Karl

AFAIK, you can fix almost everything in liux without having to even
reboot the computer.

I'm just curious. Has this problem occured using the same filesystem
(and which one is it) and has it always been on the same PC?

That PC should be screamingly fast, Speed should not be an issue. Obvious
thing to check is "top -c", to see which process, if any, is slowing down
the system.

Out of curiosity, which disk format did you install, ext2/ext3/reiser...?

My slackware v10 was doing ths same thing this morning, it was soo slow
it wasn't even fit, but after reading this post I found that it was the
nvidia installer eating up 92.5%of my cpu just rebooted and perfect...
thanks for the help

Next time you might want to just unload and reload the driver - you
will probably need to quit X, but it should still be faster than
rebooting.

i am going to do some guessing now
if your computer is up for a very long time
then linux kernel starts to do worser swapping and MM
(lately this is very rarely)
but maybe but maybe
your hd needs defrag

That's not very likely. May I ask how you would go about defragmenting,
assuming your root is not on vfat *g*?

Indeed, the defrag issue is so unlikely that we might as well assume
it's wrong. Filesystem fragmentation is not an issue for more
sophisticated filesystems (as compared to FAT), which is probably why,
despite significant demand, we don't have defragmenters. (We *do* have
anti-virus software available, because that's something clueless IT
managers are willing to spend money on.[1])

The other guess, however, is a good one. My machine which is not quite
as good as the OP's suffers seriously degraded performance in X after a
week or two. The cure is to get out of and restart X.

The parts which are wrong are to say that's "rarely", and to attribute
the cause to Linux memory management. It's a sure thing, if you use a
mostly stock Slackware as a typical workstation, and leave your X
running long enough (obviously, a shorter period for me with only 256MB
RAM than for the OP with 1GB.) And the memory management is excellent,
because getting out of X frees up all the swap.

Either X (I've seen this under both x.org and XFree86) or something I
run in X causes this issue.



[1] Not to imply that all antivirus packages are useless, of course;
server-side protection for Windows machines is a Good Thing.
