Greetings,

I want to know what is the bad effect of increasing HZ too much?
And when is too much? What problems can I expect when HZ>2000?
Can I change this value without pre-compiling the kernel?

Because all docs I found for HZ is in src/sys/conf/NOTES and it doesn't 
say much.
How can I know if my kernel misses ticks?
