Probably not.

Are you trying to solve a problem or tune network performance, or are you just
asking what happens if you twiddle this particular knob? :-)
There's a formula involving network latency and bandwidth which is relevant;
that, plus the amount of traffic (how many connections) determines how much RAM
the larger network buffer size could/will take up. You haven't told us what the
machine is being used for, either-- network tuning a fileserver talking to
clients on the LAN can be quite different than tuning a webserver feeding
clients using 56K modems.
