Hi, Does anybody have information about using jemalloc with Luminous? For what I’ve seen on the mailing list and online, bluestor crashes when using jemalloc.
We’ve been running ceph with jemalloc since Hammer, as performance with tcmalloc was terrible (We run a quite big full SSD cluster) and jemalloc was a game changer (CPU usage and latency were extremely reduced when using
jemalloc). But looks like Ceph with a recent TCmalloc library and a high thread cache work pretty well, do you have experience with that? Is jemalloc still justified or it does not make sense anymore? Thanks for your comments! Xavier. |
