I've been writing a program which reads many dozens of files.

Running it from PB, I find that the first time I run the program (after restarting the computer), it takes a while to "warm up". But running it the second time, it's much faster.

Why would this be happening? Are recently-opened files held in RAM, or in the CPU cache?

Yes, probably. Windows caches files etc. to some extent. Don't know enough about it though.

Yep, the files are cached. Tip: When your app is first run, and is idle, do a background read of the files. Then when the user wants to read the files later, it'll be lightning fast.
