Re^2: How to speed up multiple regex in a loop for a big data?

I thought \b \b pairs will do the trick since they will match word boundaries. FYI, my mapping file has no redundant entries. Please correct me if I am wrong

You're correct with the \b word boundaries. The problem case I am thinking of is the following renaming setup: `%mapper = ( foo => 'zap', zap => 'foo', )` [download] Here, foo will be replaced by "zap" in your loop and then again by "foo". But if that can't happen, all you'll gain with the large regex is speed ;)	[reply] [d/l]

Theritically, you are right. However, new names will have suffixes and prefixes around old variable names in my case. It won't happen. Thanks though.	[reply]
