If you are using windows, we now have a first 64-bit version available. 
We still need to

- complete feature parity with CPython (winconsoleio, audit events, 

- improve the installer and virtualenv compatibility

- make sure performance is equivalent to linux, especially around IO

If you cannot contribute directly to help us work on these, perhaps you 
could sponsor a directed effort. Sums on the order of $10,000 would go a 
long way toward enabling PyPy developers to work on the project.

One thing that would really help us is to get the word out via user 
stories like yours. Do you have a link to a blog post about your 
experience or would you like to write one for https://pypy.org/blog?
