This change cut roxie load time by about 3% on my local machine. I did have some large queries deployed, but no files - so unlikely to see as large a benefit in practive.

@jakesmith tagging you to debate which version to target. Should probably go in master, but change is trivial.

I wonder how much the att[@name='']/@value structure () is costing in general.. i.e. how much time would be saved if lookups were just "blah" (i.e. flat properties in the IPT ht.

I agree should be master - and think we should try to get there, where more frequent minors / and culture of super safe points, in hope that upgrades to new minors are more frequent - lessening the temptation to put safe changes into prior points.

But we're not there yet, and this is safe, and a nice optimization, so I think 9.6 is ok.

Looks good to me.
