Description: I'm searching large (500meg) log files. My CGI script
usually takes 3-4 min. to search text. Are there any tricks
(like dividing the logfile, etc.) that could make it more
efficient? Answer: How can I process large files efficiently?

You could use Tie::File to bind an array to a file, and then perform searches on the array without loading the file into memory.
"The file is not loaded into memory, so this will work even for gigantic files."
Hope this helps

| Answer: How can I process large files efficiently?
contributed by btrott Here are some tips:
- Are you loading the entire file into a variable
or processing it line by line? Process it line
by line for faster results, because you won't
be thrashing memory.
- Are you using regular expressions where
you're searching for a variable? Make sure
you're using the /o modifier if the variable
is the same each time through the loop.
