Single thread performance in Jython is also often *much* faster than CPython.

The JIT in the JVM makes Jython faster in most cases. Only startup time is a bit slower...

Ok.
That's not what I actually noticed with Jython 2.7 some time ago.
2.7 was much slower in single thread performance than CPython 2.7 in my tests. I did not test any further 3.x development of Jython , because it's basically stuck at 2.7. So it's essentatially dead from a practical pov.

A bit slower? It takes like 1000x to start up!
