whippet hacklog: adding freelists to the no-freelist space
Read OriginalThe article details an experiment to add size-segregated freelists to an Immix-inspired garbage collector's 'no-freelist' space to mitigate fragmentation from small holes. The author implemented the change but found it may interfere with the evacuation-based defragmentation mechanism, making results inconclusive. The post also discusses heap growth heuristics and performance comparisons with the BDW collector in the context of the Guile Scheme implementation.
