Please help, learning NIM to speed up Python programs, but strange results

[treeform]

I also want to point out that zippy ( <https://github.com/guzba/zippy> ) is a 
pure Nim implementation of deflate, zlib, gzip and zip that is often faster 
then the usual zlib written in C. I think this is why the Nim implementation is 
beating python's C implementation.
