Ok. A bit but fully in range for what your CPU should be capable of.

A little high, but only a little.

How man Mbit/s is your Squid server proxying?

Would probably do good with a third drive for cache.

I would also make sure all log files including swap.state is on the OS
drive, and no swap partition.

Try "downgrading" to a standard Linux-2.4 kernel.

Ok.

Quite high.. Squid will perform better if your recompile with fewer
filedescriptors, I would suggest 4096 or 6192. Note: Due to a glibc issue
the number of filedescriptors must be eventy divideable by 32 or odd
things may happen..

Ok.

Maybe, maybe not. Both Linux and FreeBSD usually performs about the same,
but your milage may vary depending on network driver quality etc..
