Python too slow?

[Gary Duzan]

I think the benefits of running Java on CPython are significantly less
than those had by running Python on the Java VM (or another VM).
Firstly, who wants to write statically typed code which then runs on a
virtual machine that can't take advantage of the type declarations?

I know it was a rhetorical question, but I wanted to point out
that this is exactly what happens with Java Generics. They didn't
want to update the type system in the JVM, so all the generic types
get thrown out by the compiler in favor of non-generic types, and
casts are inserted as necessary. Practicality wins over Purity
again.

My understanding is that while CPython performance won't be winning
any awards anytime soon, Jython and IronPython are pretty impressive
performers.

Disclaimer: I haven't personally used Jython or IronPython.

Indeed, it is as Paul Rudin said;
"It's more a continuum than that suggests. The tricky bit is deciding
in each situation where you should be on the continuum."

Secondly, isn't it just better to use a virtual machine with just-in-
time compilation and all sorts of security mechanisms if you're
wanting to write the Java code that, when compiled, can take advantage
of all that stuff? In other words: what makes CPython a compelling VM
for the Java programmer?

I agree, that's why i expecting nobody willing to. But despite of that, at
least what you've done is a proof-of-concept that java byte-code could also
be executed by python.
