Just installed CentOS 5.1 on VMware ESX and am attempting to play with the newly added tick_divider feature. It doesn't seem to be making any difference in the number of timer interrupts though. I set tick_divider=10 which should reduce the number of timer interrupts to 100.
I wrote a nasty little scripts that queries /proc/interrupts every 1 second and still see an increase each second in about 1000 interrupts.
The server is:
uname -srvmpio
Linux 2.6.18-53.1.4.el5 #1 SMP Fri Nov 30 00:45:16 EST 2007 i686 i686 i386 GNU/Linux
Obviously not running 64bit. Only one cpu has been allocated to this vm. Has anybody else used this successfully?
Could you add your finding to the bug report dealing with this subject?
