hi
I have these server nodes, doing video streaming.
and
running a server benchmark with 20 concurrent client connections. hardware is
4 IDE drives. kernel is 2.4.20-pre10 + ext3 O_DIRECT support. filesystem is
ext3.
The only system call that seems to eat any system time of importance is
'cdrom_sysctl_register'
problem is: there is no cdrom on the system!
attached is the .config and these three readprofile output files (pro[123]).
see time to see the interval they have been created in
bash-2.05# ls -l pro[1-3]
-rw-r--r-- 1 root root 13965 Jan 29 00:05 pro1
-rw-r--r-- 1 root root 14193 Jan 29 00:06 pro2
-rw-r--r-- 1 root root 15162 Jan 29 00:09 pro3

These look like bungled up profiles of the magnitude that even i couldn't
conjure up ;)

there to do!

come on, the profile data is obvious bogus. take a look at
cdrom_sysctl_register(), for chrissake.
