I had a similar problem with bge and 6.0-RELEASE. Bge works great for me in 6.2-RELEASE. So far 7.0-RELEASE looks good as well (bge-wise, I do have unresolved issues with 7). My app is TCP, cranking the TCP receive buffer way up helped, as did turning off Nagle. My bge is 1000, but connected at 100 since that is what the other end is. I saw problems at less than 20 Mbps. There is still a problem that other drivers can lock out bge for too long. For example kern/118093: firewire bus reset.
