Performance Template

Some text, with some tags that are adding to the parsing load.

This title is dynamic

Here's a table as well - lots of tags in there:
Simple
 Sample
 Real Results
 Expected Results
Template parsed each time around the loop
 100
 Slow, SGMLParser takes a while
 Slow
Template parsed once, then used multiple times
 100
 Fast!
 Hopefully faster than parsing each time
XML Version
 100
 Faster than SGML
 Still too slow
XML Version of TALTemplates
 100
 As fast as SGML
 We can hope.
Here's a list of thing:
That should do...
