LiveCode Performance Examples

I looked at some of my old stack that I knew they where slow-ish... and they're all much faster now, probably due to the new graphics engine handling stuff with lots of points better. So sadly I can't send you any slow stacks *tears up*

Nontheless here's what I tried, all stacks have to do with graphics that use markers to draw areas:

Whilst it's all well and good improving these areas, if they don't offer any real improvement to the end user, or the use case for the improvement is limited, there's little point in pursuing them.

Ideally they'd be stacks where the problem has been isolated allowing us to measure performance (and any subsequent improvements due to our work). But anything goes really. It can be surprising how such simple things can have a seemingly very large impact on the performance of an app.
