Have you actually tested the performance of 75 instances of Python
running? Do you know that it will be too slow for your server, or are you
trying to optimize before testing?
I wrote a short Python script, then launched 115 instances of Python
executing the script. There was no detectable slowdown of my system, which
is far from a high-end PC.
The details of the script aren't important. It may even be that what I
tested is not even close to the load your server needs to deal with. But
you may be surprised at just how easily even a low-end PC copes 75
instances of Python. Or perhaps not -- but the only way to tell is to try.
