1553710 - Sort the available chunks list

Status: RESOLVED FIXED

(Core :: JavaScript: GC, enhancement, P1)

Description

[Paul Bone [:pbone]]

The GC maintains a list of chunks which have some but not all arenas allocated from. If we sort this list so that we're allocating new areas from the mostly-full chunks, then we may make more chunks empty sooner and be able to release them.
