The x64 version is slightly slower and uses more memory than the x86 
version for most use cases. I think this is mostly related to V8 doing 
better optimizations for x86.

There are two reasons why you might need the x64 version:
* SSL / Crypto performance is much better with node-x64.
* If you set the right command line flags, the x64 version can use much 
more memory, while the x86 version is limited to 1GB or so.
