One of the things that can slow Rev down in a long for loop is the
building up of a long output string (I suspect that an awful lot of
copying and moving of memory starts to happen).
I made a little test of something suggested by someone on this list
(Eric Miclo?), that is, that it can be noticably quicker to build up
a long string into a file rather than a variable when dealig with a
lot of data. What I found on this 2.16G MacBookPro was that after you
get to sizes bigger than a few Mb, for each doubling of size, writing
to a file doubles the time, while using a variable quadruples the time.
If you're interested, you can get the stack I made from: http://
