Surprise...

[Curry Kenworthy]

Hey Folks,

Of course I'm interested in this thread. Always a big concern. Earlier 
this year, and last year, I was doing face-off competitions between 
LiveCode versions to test how optimization is faring.

When I get time, after some other priorities and addon updates, I would 
like to do another round of cross-version testing to see who is the 
current champion. (IIRC, I think 6.7 was last time, for Windows.)

Meanwhile....

jbv:

1. Try LC 6.5 desktop vs LC 9 desktop: how does that fare? And maybe LC 
9 desktop vs LC 9 server? I would like to distinguish LC 6/9 from LC 
desktop/server. Apples to apples testing, then conclusions are possible.

2. Sample code stack would be great.

Optimizing our code is a good thing, and something I am paranoid about 
and specialize in helping people with. Optimizing LC's own code is also 
a good thing, and really the bigger question here perhaps for this thread!

So...I'll be quietly following this thread. No time to participate yet, 
but will later.

Best wishes,
