More good news: The PDFL doesn't lock a file when reading from it, so multiple processes can read from the same PDF at the same time. Multiple writes are a problem for obvious reasons. I used the number "50" above because that's the largest concurrency test that I can remember running. In my experience, optimal throughput on my app was achieved at around 10-15 processes per CPU. The PDFL spent a lot of time IO bound. Anything more than that and the CPU started to spend more time switching processes than it saved switching away from IO-bound proecesses.
