(The time deltas for pretty much all network traffic was basically next to zero.) Other than the shortened delays, there were no other obvious differences between the traces. ok; there must be something different though up until the point where the client does/does not delay before sending the packet odd number of packets up until this point with Apache, but even with the other servers? (odd is where the delay kicks in, right?) --/-- It is probably present in all that info somewhere, but how do we know that the TCP window size for IIS is not larger than the one for Apache? --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
