JVM was wrote in C
Thats not true - java is slower than C - because of its dynamic nature and runtime checks (like boundary checks and so on). Just because it is written in C doesn't sayy anything beyond that it runs on computers...
Python is even more dynamic than java - which maks CPython already slwoerr than java. Adding that togehter, and you are there.
it should not slow than CPython, Jython script was compiled to java class before it run. So it should not be so slow than CPython I think.
Your jython code is _not_ compiled to java. Especially not with eval, which whole purpose is of being interpreted at runtime. And even if you used jythonc - it wouldn't make much of a difference, as jythonc is not so much a compiler for speed reasons but sort of a freezing tool that makes jython objects callable from java. Not more, not less.
And you still haven't answered the question _why_ you need that performance. If thats your ultimate goal - use assembler :)
