Re^4: Performance Trap - Opening/Closing Files Inside a Loop

[Limbic~Region]

kvale,
I expect a single hash lookup to be much faster than a pair of system calls for opening and closing files

I don't want to sound like I am beating a dead horse here, but that sounds identical to my solution except your way seems like it would be slower because instead of figuring it out as you go, you are processing the files twice.
