I have a C++ program that opens, gets a little data from, and closes about 5000 files. Now if I run the program when I first boot up, the running time is from about 10 seconds to a minute. Subsequently, the program runs in well inter one second. Buffering -- right?
So I changed a parameter, so the program gets a different (albeit similar) 5000 files from a different directory. Running time on the first try: well under one second.
How about that?

Thanks for your comments. Mike.
