Allocate HashMapEntry on OldGen #1344

Closed ftanuma closed 1 month ago

ftanuma commented 2 months ago

Summary: Allocate HashMapEntry if the hash table is on OldGen. This gives us much better performance when large number of entires (like 10M entries) are inserted to Set or Map. At early insertion, everything will be allocated on YoungGen, then at some point, YoungGen collection happens and the hash table will be moved to OldGen. After that, all the allocation and rehash will happen on OldGen.
