Performance tuning w/kernel SYSCTL options

I'd suggest you to read:
TCP/IP Illustrated, Volume 1: The Protocols, Addison-Wesley, 1994, ISBN 0-201-63346-9
There's no clear-cut answer to the questions below. It's always
a trade-off and most of the time the default values are the
best but for your situation there are lots of factors that
can be determinant other than the information you provided.
Go for this book. You'll enjoy reading it.
God Bless Ricard.
