FreeBSD 6.0 GENERIC Kernel perfomance

[Dmytro Surovtsev]

I was not really honest: I did compiled the kernel without -g option. 
Nothing different. The only thing that looks like help was compile 
without PREEMPTIVE option. I'm sorry very much for FreeBSD that I like 
many years. I do not think that racing for issuing the new RELEASE (so 
called in this case) in proper time costs the reliability and robustness 
   we all appreciated all theese years.

Dmytro,

The stock Generic Kernel for 6.0-Release has debugging features which
according to the kernel developement team where left in during release.

Try to recompile the Generic Kernel with the option debug -g commented
out and see if that helps with the speed issues you have encountered.

Thanks,
