Socket performance
in [Python]

From: Navkirat Singh on 23 Jul 2010 20:06 Hey Everyone, I had a question, programming sockets, what are the things that would degrade performance and what steps could help in a performance boost? I would also appreciate being pointed to some formal documentation or article. I am new to this. Warm regards, Nav

You could do the socket stuff in another thread so that it's not waiting for the processing to finish while there is data available, and use a queue to transfer the data between that thread and the processing thread.

Remember the old saying, “premature optimization is the root of all evil”. Have you actually got some code working properly first, before worrying about how good or bad its performance is? -- Lawrence trying not to say “performant” :)

Its always good to have a map right? |
