allocators are so simple to just swap into your program. if you can put together a few representative workloads, you should just try out a few allocators and profile whatever metrics you care about.
I am intrigued.
Is there a source for them?
for us, tc was among the fastest in runtime while being very space efficient [0]. large rust application using far too many threads.
we’ve since also had great success with tc’s built in profiling tools.
We've tried tcmalloc, too. I don't remember the exact details, but we basically ended using jemalloc because it was using way less memory.
Same story with mimalloc - it usually provided a tiny bit more speed, but required more cpu and memory.
to confirm, you were using tcmalloc from https://github.com/google/tcmalloc and not from https://github.com/gperftools/gperftools, right?
the latter is a lot worse iiuc.
