I think his performance gain was quite a bit more... Bob is a good old friend (turned boss for a few years, turned good friend again), I was privvy to daily updates on his transitions and performance gains - and he completely sold me. Twisted is really great ( though the syntax can be a bit of a bitch )... we just outgrew it (it became the bottleneck, not our DB or network architecture). I think it maxxed out at indexing 1MM online identities a day ( which translated to about 15MM web queries ) (per machine, of course). At one point we had 100MM profiles tracked, and a backlog of 500MM to get to -- under twisted there was no way we could start re-queing and updating our index as fast as we'd like. The next level would be C.. or erlang. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
