Yep, I've seen that. :-)

It's not entirely slower, but mainly slower.

OTOH, if you split a job into two threads on a twin-core machine,
IronPython performance will increase dramatically whilst CPython will
go down...

Additionally, extending IronPython from C# is orders of magnitude
easier than extending CPython from C.
