Well, it depends on what the server is being used for, right? If it's a small object proxy/web server sure. But if it's a streaming server you may only need a few thousand sockets but very deep send buffers. Honestly, I'd really like the OP to come to us with workloads that aren't working and get them fixed. We're a pretty smart bunch over here and it's highly likely that both he and we would learn from the process. :) And double honestly, it may be nice to print out a "running out of sockets!" warning, as well as a "running out of mbufs!" warning. Rate limited, so people don't get spammed. But a gentle notification that they should retune some stuff would be user-friendly. AdrianReceived on Fri Oct 05 2012 - 12:11:16 UTC
