Sergiy Kuryata	d67fe5d26a	Rotate through arenas in mi_arenas_try_purge instead of always purging arena 0 if visit_all is false.	2024-11-05 13:00:50 -08:00
Sergiy Kuryata	2a3b8eb696	Do not call mi_abandoned_collect on allocation path as it consumes substantial amount of CPU time	2024-11-04 21:22:45 -08:00
Sergiy Kuryata	911de68d3e	Experimental optimization for the segment reclamation logic. ... The goal is to improve efficiency of finding an abandoned segment that contains free space of the required size. This change adds a free space bitmask to the segment object. More optimal place for the bitmask could be in the arena (i.e. extend the arena’s bitmask for abandoned segments to include size information too).	2024-10-31 16:53:14 -07:00
Sergiy Kuryata	b604099334	Experimental improvements to reduce memory usage ... 1. Prefer to use more loaded pages when allocating 2. Add an option to restrict unbounded heap growth and allow the excessive memory allocations to be re-used by other threads	2024-10-11 10:35:51 -07:00
