Many users have reported great results with satellite connections. In general you should optimize your system as you do for any broadband connection. Setting TCP Receive Window to a very high value in Advanced Optimizations can often give very good results since satellite connections have very high latency.
We did received this comment from a satellite network owner: > We recently set up a new Internet via Satellite service for the UK market, during initial testing we were having speed and consistency problems when we connected to the service using a standard 56Kbps modem, we tried for days to resolve the problems, with little success. We decided to give TweakMASTER a try, and what a result. Within a matter of seconds, we had consistently high speeds of over 60KB/s. Thanks TweakMASTER you saved our service!
