New primelimit-process? (apparently much Time-consuming)

[Gottfried Helms <Gottfried.Helms@t-online.de>]

Dear community -

 I just tried the gp2.16.2 (64 bit) (developers) version and
 was surprised about a very long loading time of the system.

 With the gp2.16.0 (64 bit) version there has never been no such
 long waiting time.

 I tried changing of parameters in the gprc.txt and others in
 my starting routine, and it focused on the "primelimit"-parameter
 in the gprc.txt file.

 Here screenshots from the starting process (by my GP-interface,
 but the difference occured even when started as dos-process
 in a "cmd"-window, so this is no effect of my GP-interface)

This takes no time to load: (using gp 2.16.0):

==============================================================

Note the "increasing stacksize" messages which occur in the 2.16.2
version.

If I use even primelimit=100000000 (=100 000 000) in gprc.txt,
which is what I've done in the last year by default, then the new
loading time increased to, say, 20 secs and even the stack-allocation
comments go up to 1GB, while with version 2.16.0 nothing similar
occurs.

Kind regards -
