[HECnet] PyPy

I was just reading about an alternate Python implementation called PyPy, which uses a "just in time" compiler. With that it's supposed to be potentially a lot faster than regular Python, for code that does a fair amount of computation. While PyDECnet does plenty of I/O, things like packet parsing are fairly time consuming. I've optimized it a bit but the structure I adopted only allows for so much. I tried PyPy to see if it supports PyDECnet. The answer is yes, after I removed some code from two files that wasn't even used in the first place... Just to see if it makes a big difference, I did a large loop test: "ncp loop nod 0 count 50000 len 400". On my Mac (ARM) laptop, that takes 6.3 seconds with Python 3.13, and 1.2 seconds with PyPy. More testing is needed but this is interesting. paul
