Hi, I'd like to know if there's a way to determine which is the best buffer size to use when you have to send() and recv() some data over the network. I have an FTP server application which, on data channel, uses 8192 bytes as buffer for both incoming and outgoing data. Some time ago I received a report from a guy [1] who stated that changing the buffers from 8192 to 4096 results in a drastical speed improvement. I tried to make some tests by using different buffer sizes, from 4 Kb to 256 Kb, but I'm not sure which one to use as default in my application since I noticed they can vary from different OSes. Is there a recommended way to determine the best buffer size to use?
Thanks in advance [1] http://groups.google.com/group/pyftpdlib/browse_thread/thread/f13a82b... --- Giampaolo http://code.google.com/p/pyftpdlib/ -- http://mail.python.org/mailman/listinfo/python-list
