[IronPython] Looping in IronPython - should it be linear?

[Robert Wierschke]

Please post the code of your loop.

Do you instantiate objectn in your loop? I guess the memory management / garbage collection is responsible for the additional required time.

Also the code runs in the .NET VM and the VM might do other things as well (JIT compilation, ...).
