Now I'm worried jemalloc support in ceph about. I'm not sure about the current status of the bug: I don't know why jemalloc and rocksdb were not working together, and I'm not sure whether the fix is simple (build option?) or more complex. It's also not clear whether jemalloc is going to be helpful or that this is important. jemalloc was much better than tcmalloc with SimpleMessenger, but the default is now AsyncMessenger and there wasn't much of a delta. Either way, jemalloc is a runtime option, so either it works or it doesn't, but the fix is to restart the daemons--there's no risk. sage
