@bea dlmalloc is oldschool "regular", but it depends on your system whats default.
jemalloc fragments (very) much less than dl for sure, but is also very very predictable
tcmalloc fragments less but at the expense of using WAY more memory on some programs
@hellamander @bea is it still per process per size pools with out of band metadata?
@Fuego according to one thing i read this morning it's plain old malloc but someone the other day mentioned tcmalloc so honestly i'm not sure. apparently jemalloc fragments less than both so we'll see if it helps
