Re: recommandations for a home Gigabit switch

Just curious... John-Paul... but how much performance boost would you
expect
with being able to setup for jumbo frames? Something like that would
require nics that support jumbos also... Sounds a bit expensive, but if
the
performance increase is great enough, maybe it'd be worth the cost.

I think that you'd see a BIG boost when moving large files. It allows for
a lot less handshaking during the transfer process.

In this case, where the hard drives are a limitation before the Gig-E,
it's probably not huge. Bogging down from interrupts was more of a problem
when CPUs were more anemic, and before interrupt coalescing/NAPI were in
use. If his NICs don't support jumbo frames already, it's probably not
worth it in his case to buy new ones.
