That depends on your usage pattern. There are certainly cases where the
Win32 version will be significantly slower.
For example, if you open a lot of new connections, that is a lot more
expensive on Windows since each connection needs to execute a new
backend due to the lack of fork().
I don't think you'll find any case where the Windows version is faster
than Linux ;-) But to get a good answer on if the difference is
significant enough to matter, you really need to run some kind of simple
benchmark on *your* workload.
