Author here. The interesting point was that RSS is much too large with glibc malloc + RocksDB/MyRocks. The performance differences aren't a big deal, but OOM because RSS is 2X or 3X larger than it should be is a big deal. Of course, that problem is workload specific, but RocksDB/MyRocks are a workload on which I focus. I lurk on email lists for RocksDB and OOM from glibc malloc is a problem for users -- the solution is easy, use jemalloc or tcmalloc. |
