How were you detecting these times? Can we attach gdb to the process and trigger an all-threads stack dump when it happens? >My next attempt to improve performance was going to be to run trac in >subprocesses instead of threads. That would hopefully substantially >fix the delay problem. That would be interesting. I thought it would be easy to add multiprocess support to the Twisted Web WSGI container, but I have since realized that was a pretty stupidly naive belief. :/ Still, perhaps it won't be impossible. Could we start off just running multiple twistds, though?
