in reply to Efficient Way to Parse a Large Log File with a Large Regex

If you just want to check for the presence of one of a group of IPs it'd be much more efficient to build a hash of the IPs up front, and then parse out the IP from each record and do an exists $wanted{ $curIP } to tell if it's interesting or not.
