Re: icon running slow when occupying large memory spaces?

First of all, what's "GC" and how would I force the heap size?

I should have been more specific about what I encountered, however.
I would have expected that anything to do with large data structures
would have taken a long time since there would have been a lot of table
or list items to traverse.  However, the problem that was most striking
was a call to the built-in "system()" routine from a 4GB program.  It
took around 0.8sec just to execute this commnd, exclusive of anything
the system command itself sent to the OS.
When I ran the same routine from a small icon program, the system call
was instantaneous.
