Hello,
Im a 20+ years professional Powerbuilder developer thats experiencing slow object opening & saving in Appeon PB on large projects.
Adaptive Server Anywhere as backend DB and win 10 as OS.
Opening, changing and saving menu objects or other large objects with a lot of code has started to be very time consuming.
Over time the items starts to get slower and slower to open. A full rebuild used to help a lot, but after a while, even that doesnt help mutch.
Likewise the time spent on compiling goes up by 30%.
Its a rather large PFC project with inheritance and object orientation, aprox 12000 objects of various size.
I've done the usual "exclude files & folders" from virus scan, that actually speeded up things a lot, but it does not affect this issue.
The auto script feature is off.

So far, I've found a bit strange workaround. I've got 3 laptops, a workplace Dell Precision M6700 running on Samsung magican SSD RAM buffer (fast as a rocket), then a Dell Precision 7750 and a Lenovo t14s best fit for travel. I moved some sourcecode around on these machines, "et viola" the menuobject opened ligthening fast(!) The trick is to use a laptop where the code was not last compiled.

This leads me to suspect some fishy indexing or broken internal referencing is going on in Appeon while they are compiling the code.
It could ofcourse be a windows issue, that is, windows let go of some history on the object when its "new". 
Any ideas what might may be going on? 

Regards
Brage
