It's been a while since I benchmarked Rev's field loading and buffering, 
but suffice to say it was impressive.  Loading up a field with the 
entire Bible (courtesy of the Gutenberg Ebooks Project) took a while to 
load, but once loaded it scrolled more smoothly than a fourth as much 
text in Microsoft Word.

In my experience, the biggest slowdown with loading a field with large 
amounts of text is when the engine has to determine soft breaks for 
lines.  This isn't an issue in script editors, since the dontWrap of the 
field is set to true leaving the developer in control of where lines wrap.

In terms of overall performance, 2300 lines of hard-wrapped text in a 
field with the dontWrap set should be pretty snappy to load, and very 
responsive to scrolling.

If there's a question about performance of the raw native field control 
relative to whatever processing GLX2 may be doing to prep display, you 
can simply try this:

   put the script of stack "StackWithABunchOfcode"

That will dump the text of the script into the Message Box.  If it takes 
about the same time as it does to open GLX2 with the same script, the 
issue lies elsewhere.
