Where to optimize network setting?

Where do I go to change MTU,RWIN,TTL, and etc, to optimize my connection?
I'm running SUSE 10

Thanks

those things are found in the /proc filesystem and are adjusted
using echo NewValue > parameter_name ..

however, you should have very little need to make any adjustments at all.

you should find all of the defaults are perfectly suitable for most every terrestrial configuration.
