Looking at the syscalls in more depth, I wrote a small and simple program that _only_ does syscalls in a big loop, see attachment. Just uncomment the syscall that you want to benchmark. Here are the results for Suse 10.0, 10.2 (rescue system) and 10.3. Hopefully I get the table right this time... 10.0 10.2 10.3 ----- ----- ----- gethostname 8.57 11.77 14.47 seconds/run stat 14.49 19,38 21.90 seconds/run getuid 2.78 5.43 8.41 seconds/run close(dup) 9.09 15.83 21.93 seconds/run Looks like syscalls have been getting slower over time. I'm just amazed _how_ much slower this is. Did the same thing happen for the vanilla kernel? Regards nordi
