high peak RSS on `hmmer` from SPEC 2006

Open bobby-stripe opened this issue 5 years ago • 0 comments

it is unclear what is going on here; median RSS is ~ 12 MB with mesh, but "only" 4 with jemalloc + libc. Our Peak RSS with Mesh is much higher too - 66 MB compared to 25 with other allocators.

Its possible this is an issue where hmmer callocs memory and we eagerly write to it, and other allocators know that "fresh" pages are zero'd already (and don't count against RSS).
