VERY slow apps. loading


Hi,

It is taking an age (5-6 mins) to fully
populate my KDE desktop (basic, as
installed)
and about 40-50 secs to start a small K
application.

I have cross-over-office to run M$ XL &
Word from, these load and run instantly.

Being new to Linux I am at a loss to what my problem is
caused by.

I'm using:
Suse 8.1
Athlon 1800
1 Gig memory
HD patitioned as
--20 G Win 98
--20 G Win2K
--20 G Linux Ext3
Adaptec SCSI card
SCSI DVD player
SCSI Zip
IDE DVD R/W
FireWire port
USB ports
BIOS is set for plug&play (have tried otherwise to no avail)


I ran strace on some of the K programs and it records to
file as if all is well. This is from KPoker

:/opt/kde3/bin # strace -c -i kpoker
<Start>
upeek: ptrace(PTRACE_PEEKUSER, 1485,48,0): No such process
[????????] execve("/opt/kde3/bin/kpoker", ["kpoker"], [/* 59 vars */]) = 0

..however the process to get the poker window on the screen
takes about 25 secs!..stalling at the same point every time
with 'strace' displaying the results on screen.

I have tried several 'installs' trying to disable various bits of the hardware
without any success.

Unable to track down what is actually happening when the program goes for a
snooze (can't get KDE system Guard to tell me either), I'm hoping that someone
can point me in the correct direction.

Thanks,
peteheff

maybe something is hogging all the cpu? see if "top" gives you any insights.

acid_kewpie,
..tried 'top' while trying to load one of the K apps but there was nothing that 'jumped out' at me (but kdeinit uses a lot of memory)

Something that may be an eureka to you guys is a 'modprobe' error that I get; to the effect that it does not locate char-major 226?

For what it's worth here is a copy of the 'top' about 10 secs into loading, and as I said not much was moving.

Hi,

Can you try this out ?

Please create a bootdisk floppy ( mkbootdisk --device /dev/fd0 <kernel-Version>.

Set BIOS to boot from floppy drive as first bootable drive.

Boot from floppy using this and THEN start XWindows.

Check the speed. I suspect this is related to my problem too which is posted as "Xwindows is slow with multi-partitioning".

Didn't do the floppy thing but installed another HD and put Linux onto it using the entire drive.

Although I did not spend any time setting up graphics cards etc. it loaded and ran the K programs about 150 faster than on the original install (i.e. did not go for a 25 second snooze!).

So rk_carols' point about the partitioning seems credible and like rk_carol I have looked around and found nothing related to this sort of problem.

While inserting my original HD today I accidentally knocked my network card out and my original install ran fine!

So, off to find out what sort of conflict my network card was causing.

Charlie's problem is NOT related to the XWindows being slow on startup. It is more related to the nsswitch / DNS lookup option that tries to resolve IP to Names.

We need an X-pert ( I am going to start digging into this when I find some time ( Alas, I have heard this one before ! ).
