[rdtsc]

Good point. I use gevent and now switching back to eventlet. But that is a different post perhaps.

Not only do you get more threads with greenlet you also don't have to worry about a whole class of synchronization side-effects since a greenlet will only switch contexts on an IO operation. (Now some might argue that is bad since you could be calling a function and not know what happens in side or what might happen in the future so you should lock anyway).

Out of curiosity, why the switch? I went with gevent pretty early on because it seemed like eventlet had some weird quirks, but I have to admit never really giving it a close look.

Because it is supported in older Pythons on some servers I work on. Works with PyPy. It has less dependencies (just greenlet) and easier to build.

gevent also has been thrashing around is it 1.0 beta? Switching to libev or libevent. And eventlet picked up more steam with more test coverage.

So no one big issue just a bunch of small ones.
