Read and Analyze Giant Files

[Yennie at aol.com]

Problem here most likely is that you are trying to read the entire 300MB file 
into memory at once. Unless you have an extra 300MB block of RAM floating 
around, this will start beating on virtual memory pretty hard (and 
increasingly slow).

You'll notice that your non-MetaCard script reads one line at a time- I would 
suggest doing the same.
If you are just looking for occurences of a single string, you could also try 
using the grep command-line tool. Type "man grep" into the Terminal for 
syntax.

HTH,
Brian
