Dear developers,
I have compared before-after this patch two of my programs running on a Mac:
On a client calling an external server (thus most of the time waiting for a
response) I noted a 5% time saving from 4000 assertions.
On a text parser I noted an 8% time improvement when parsing 11000 files.
Both programs are non-optimized, pure (oo)Rexx code programs, no BSF involved
+ no side effects whatsoever.
Impressive!
Hälsningar/Regards/Grüsse,
P.O. Jonsson
