How do you handle the poor performance of LC 7?

Earlier today I jumped in briefly on this thread to confirm I had also 
experienced slower performance and on the same hand I'd like to jump 
back in now in full agreement with Trevor.  Coincidentally, just 
yesterday I was railing on to my wife (an excellent listener) about the 
old Hypercard days back in the late 1980's and how a very secretive 
Apple strung us along for years 'leading us to believe' they were 
continuing to support it, when if fact it was nothing more than that, 
'leading us on'.

In sharp contrast, the Livecode team has been nothing but open, 
visionary, dedicated and productive.  They've consistently done an 
excellent job of keeping Livecode on the leading edge.  This week I 
finally got around to building an app for iPhone/android.  It was 
relatively easy and I'm excited to delve into the many features these 
devices offer that I can now tap into via Livecode.  I thought of the 
conference in Edinburgh I attended years ago when Kevin Miller was 
almost beside himself with excitement as he shared his first successes 
in that area.

I've gotten around the slower performance in the script editor by 
dividing large scripts into multiple libraries, something which is 
probably good coding practice I should have been doing anyway. Regarding 
the slower production performance, it seems we have a variety of sound 
suggestions here which will help any of us address that issue while 
continuing to take advantage of the latest and greatest coming out of
