Hello!
What value of HZ option would you recommend for a hosting (web) server
with a lot of processes (about 900) and polling off (as decided from
previous discussion polling is useless in this situation).
Is this an SMP system? If so you'd probably be well served by testing the
latest 7.0-current (which will soon be a beta for 7.0-release) with the
ULE scheduler. That's likely to have more benefit for you than changing
HZ, although setting it to 100 is probably going to be better than 1000
for reasons others have already mentioned.

Hello,
Thank you for the nice discussion guys, I have server with dual xeon
cpus, and C2D I switched kern.hz to 100 instead of 1000.
