High CPU usage on host system when running FreeBSD as a guest OS inside vmware server.
After installing FreeBSD 6.1 as a guest OS inside vmware server alongside a Debian vmware
instance, I noticed tha the FreeBSD instance was using much more CPU then the Debian instance,
while both were idle.
Some testing revealed that setting the following in FreeBSD's /boot/loader.conf sensibly
decreased the number of interrupts per second, hence lowering the overall background CPU usage:
kern.hz="100"
I'm not aware of any negative side effects of this setting. If you experience any negative
side effects, feel free to report them to
us.
