This is a second time around that IronPython piqued my interest
sufficiently to create a toy program to benchmark it and I must say
the results are not encouraging:

$ python bench.py
Elapsed time: 1.10 s

$ ipy bench.py
Elapsed time:65.01 s

and here is the benchmark program:

import time
start = time.time()

def foo(a):
    return a * a

data = {}
for i in xrange( 10**6 ):
    data[i] = foo(i)

print 'Elapsed time:%5.2f s' % ( time.time() - start)
