I am currently developing an application (using CLIM v. 1.0) which
involves a significant amount of memory manipulating arrays. When
running on the Symbolics fits in a world using about 80 Mb. of paging
area. On the Macintosh under MCL 2.0b1p3 I initially tried running
under 5 Mb. of real memory (and failed). I then turned on virtual
memory under system 7 and gave MCL 20 Mb. The result has been GC
hell.
I am interested in heuristics and/or parameters for increasing
effectiveness of the MCL garbage collector. Is the MCL garbage
collector unworkable with virtual memory? Any and all thoughts on
this matter would be greatly appreciated.
Thank-you.
