 Well. I dont think either that my test was really exact estimation.
And it was just "5-minutes work" for fun after a workday..
I used translators "as is", I hadn't change any settings, 
and, speaking frankly, I wanted to know how fast was java, 
not python..
But if you want to know versions of translators, 

tcl/tk 8.0
perl 5.005
python 1.52
C - gcc 2.95, without optim. just " gcc sieve.c ",
   with optimization "gcc -O2 sieve.c "
Java without JIT -JDK 1.1.7 from blackdown.org 
and with JIT - kaffe (I can't remember version, it was from 
  distribution of linux mandrake 7)
pascal - fpc

Computer Pentium 233MMX 80 Mb Ram linux, mandrake 7

Sorry again, I don't think that it was strong enough test, but
I thought it might be interesting....
