I stumbled across a comment in this post that mentioned that the %SYS.GlobalQuery is a potentially faster alternative to %GSIZE. I tested it out and while I like the %SYS.GlobalQuery I noticed that it has some size discrepancies against a %GSIZE with details. Can anyone tell me which is more accurate for estimating the size of globals?
Here is an example of one of the differences I saw. From this it looks like the size is estimated to about 70gb from %GSIZE and about 67gb from %SYS.GlobalQuery.
