64 Bit Python Geoprocess Speed vs 32 Bit Python Geoprocess Speed

I ran a python script with both the 64 bit python.exe and 32 bit python.exe. I was expecting the 64 bit python.exe to be faster (not sure how much faster it should be), but it was actually slower.

Does this make any sense?

Are there any settings that need to be looked at to fix this, if this is not expected behavior?

Thank you.
