Have you done any measurements that show your TCP/IP performance is
bad? AFAIK, MTUSpeed simply fixes stupid defaults in several
parameters of Windows' stack. The rationale behind such a utility,
namely, that you can't fix the problem at the source, doesn't exist
in Linux. I'm not saying that network performance is necessarily
optimal in a default Linux installation, but that I would expect the
obvious faults to have been fixed on lkml.
So my suggesions:
- Don't expect a magic-potion utility to improve performance. If there
were changes to make, they probably made it to the standard tree.
- Measure. See what the bottlenecks are. Then work on fixing them.
This is probably the hardest step.
- During the Mindcraft benchmark hoo-ha, lots of "tuning your server"
pages had sprung up. Links to some of them were were posted on lkml,
and you can try to search the archives of that list for hints. I
also vaguely remember one linked to from linux.com .
