My first thought here was that maybe you're seeing the effects of nagle[1] + delayed acks on the other side. On Unix, normally something like a thrift client would set TCP_NODELAY on its socket to avoid the problem. I'm not sure whether or not this is a reasonable hypothesis with C# + Thrift on Windows. Sorry, I don't know what the easy fix is either but perhaps it might help dig further. [1] http://en.wikipedia.org/wiki/Nagle's_algorithm -- / Peter Schuller
