[Twisted-Python] CPU usage.
hi I use twisted to build some web services, using twistd to start a application. When I start the twistd, and without any connection, the cpu usage of twistd process comes to about 10%. I don't think it's normal. I think it should be much low than this num. But I don't know how to find the problem is.Would anyone be pleased to help me? Thanks.

Twisted doesn't use 10% CPU by default; chances are it's some code you wrote. Have you tried using a profiler (e.g. cProfile)?
How can i use cProfile with twisted? Is there any guide or example? Thank you very much. I googled and stackoverflowed ,but didn't find any examples. 在 2012-4-26，下午6:00， Itamar Turner-Trauring 写道：
