Choose the Garbage Collector used by the translated program.
-The good performing collectors are "hybrid" and "minimark".
-The default is "minimark".
+The recommended default is "incminimark".
- "ref": reference counting. Takes very long to translate and the result is
- slow.
+ slow. Used only for tests. Don't use it for real RPython programs.
- - "marksweep": naive mark & sweep.
+ - "none": no GC. Leaks everything. Don't use it for real RPython
+ programs: the rate of leaking is immense.
- "semispace": a copying semi-space GC.
- "generation": a generational GC using the semi-space GC for the
older generation.
- - "boehm": use the Boehm conservative GC.
-
- "hybrid": a hybrid collector of "generation" together with a
mark-n-sweep old space
- - "markcompact": a slow, but memory-efficient collector,
- influenced e.g. by Smalltalk systems.
+ - "boehm": use the Boehm conservative GC.
- "minimark": a generational mark-n-sweep collector with good
performance. Includes page marking for large arrays.
+
+ - "incminimark": like minimark, but adds incremental major
+ collections. Seems to come with no performance drawback over
+ "minimark", so it is the default. A few recent features of PyPy
+ (like cpyext) are only working with this GC.
