Regex (MatchText) speed

[Troy Rollins]

I took a look through the archives, and didn't see anything definitive 
about speed advantages in Rev of using matchText with regEx, compared 
to more basic "chunking" techniques - including "contains". I find Rev 
is a string handling monster with Transcript alone, but don't know just 
what it is actually doing with Regex... for instance is it "a 
Transcript regex engine" or some kind of compiled external? Or a 
compiled internal?

I noted that Tuviah says that the regex engine caches the last 20 
patterns, but...

Anyone have a real-world sense of the speed difference? I have a 
parsing routine which I put together hastily, knowing that it would 
need to be later optimized. I'm edging in on that optimization phase, 
and I'm wondering what angle I might want to approach it. Speed is 
definitely a concern.
