[IronPython] IronPython Start-up Time

playing around a bit with IronPython I noticed that the start-up time is
quite long

Something around ~12s for the initial launch and around ~3,5s for each
launch executing
    import sys
with IronPython-2.0A2\ipy.exe (on a Core Duo 2Ghz 2GB)

I am not complaining, just curious.
Is this simply because loading the CLR/DLR takes so much time?
And what is with the 3.5s for successive start-ups?

For comparison CPython needs ~2s for the initial and
~0.2s for successive start-ups.


Btw I used the simple C++ program
// Compile with
//    cl /Feuxtime.exe /EHsc uxtime.cpp
//    uxtime.exe "PATH_TO_IronPython\ipy.exe simplyExit.py"
#include <stdio.h>
#include <ctime>
#include <stdlib.h >

int main( int argc, char**argv)
    int c_start = clock();
    system( argv[1]);
    int c_end = clock();
    printf("%d\n", ((double)(c_end - c_start)) / CLOCKS_PER_SEC );
