The original performance specification was "...receive up to 2000 calls per minute". I don't believe that means that a call has to be serviced in under 30ms (wall-clock time) but total CPU time would have to be <30ms in order to not fall behind under a constant 2000 requests/second load. So we can probably remove database connection and communication time (i.e. IO-bound components). Still, it's a lot tighter than I though it would be: % time python -c "import SimpleXMLRPCServer; import MySQLdb" real 0m0.144s user 0m0.046s sys 0m0.064s So it's already almost 4x too slow. But I'm running this on Ubuntu, running on VMWare on my 1.6GHz Pentium-M laptop. I would assume that a beefy server would do a lot better.
