You adjusted osd_memory_target?  Higher than the default 4GB?

> Another thing that we've found is that rocksdb can become quite slow if it doesn't have enough memory for internal caches. As our cluster usage has grown, we've needed to increase OSD memory in accordance with bucket index pool usage. One one cluster, we found that increasing OSD memory improved rocksdb latencies by over 10x.
