I suspect it depends on how long the parsing of data takes.

If it's fast, trying to read 50 files simultaneously will likely (I'm
guessing) cause disk thrashing that will slow you down.

If processing each file is much longer than reading the file from
disk, and you have multiple CPUs, and can use native threads, and can
schedule the read of one file to begin after another ends...probably
you can speed things up.

I made all those answers up, but I'm guessing they're correct :)
