windows defender issues? & other AV issues?

Curry, I haven't questioned your findings in the report.  On the 
contrary, I confirmed them.

We don't disagree on observable data.

We merely differ on focus:

Few of my customers use the LC Script Editor, so they don't care about 
it. But they do use the software that we ship to them.

And since we can find many stories about this in apps other than LC, 
like those I found with the DuckDuckGo search I did the other day, the 
element from the many forum posts on this that caught my attention was 
that every one of them who replied back said that turning off RTP was a 
satisfying result.

That got me focused on the AV aspect of this, when Tom started this 
thread looking at AV issues.

As for the SE, I share the interest but not the concern.  Milby's 
looking at the prefs angle, Mark Waddingham is already working on 
arrays, so both on-disk and in-memory optimizations are under way; that 
much is in the can.  #21604 is indeed a good report, helpful on both 
sides. It'll be closed soon, so now I'm free to consider the part of his 
discovery that impacts what we ourselves ship:

How many devs among us are shipping apps which rely on frequent disk saves?

Are you seeing a difference with the impact of RTP on vs off?

This will definitely prompt me to spend more time testing on Windows...
