I have a script that opens a TCP socket and then sends an XML request using SSL over the socket, it then receives an answer back from the server. The whole send and receive is taking between 160 and 175 milliseconds total (not including opening the socket) but I know others using PHP and Perl have this down to around 130 milliseconds and I wonder if Ruby has any tricks up its sleeve that would speed thing up a little. ---

Show us your code. It’s impossible to say that the performance issue is with network and not with other processing you are performing on the data from what little you’ve said. Barring that, take a look at the Eventmachine library (available as a gem). It allows you to build clients and servers using non-blocking I/O. cr ---

Show your code as others have said. Using tcpdump or wireshark, measure exactly how much of this delay is for the far-end server processing and responding. If the far-end server is taking less than 100ms to respond, you could try the TCP\_NODELAY or TCP\_CORK socket options on the ruby client side. ---
