HP 49G / HP 50G memory

[TravisE]

One incidental thing I've noticed about storing and running libraries I've written in Port 1 vs. other ports is that there is often a bit of flickering “snow” on the screen at times if they run from Port 1, whereas I don't notice this effect if they run from Port 2 or Port 0.

Oddly enough, despite what was said above, it seems that in some of my informal tests, programs from libraries stored in Port 1 appear to run slightly slower on my 50g than from Port 2. For instance, I tried executing a loop that repeatedly called a short UserRPL program I had stored in a library; with the library in Port 1, I got fewer average executions per second than in Port 2, and in Port 2 I got fewer executions per second than I got with the library in Port 0. However, the increase in performance from Port 1 to Port 2, or from Port 2 to Port 0, was only on the order of around 3 to 5 percent or so.

However, in my case these were quick tests that I didn't perform too terribly rigorously, so it's possible there are several variables I didn't account for.
