Todd Lipcon updated KUDU-1366:
------------------------------
Attachment: Kudu Benchmarks.pdf
attached benchmark report of tcmalloc vs jemalloc. A few big wins, a few big
losses (particularly wire_protocol-test got twice as slow). Worth looking into
what happened there, since it probably is a big factor in why some of the macro
benchmarks got slower.
> Consider switching to jemalloc

> We spend a fair amount of time in the allocator. While we could spend some
> time trying to use arenas more, it's also worth considering switching
> allocators. I ran a few quick tests with jemalloc 4.1 and it seems like it
> might be better than the version of tcmalloc that we use (and has much more
> active development)
