If you want my guess, the cost of going to multiple processes would be to do with passing data back and forth between them. Why is Python being embedded in another application? Sounds like there's data moving from C to Python to C, ergo breaking that into separate processes means lots of IPC. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
