Description
Our recent RGW thread pool size profiling (RHEL 9.2, Ceph 18.2.0-131) revealed that for both smaller (max 256KB) and larger (max 256MB) object sizes, the default rgw_thread_pool_size and rgw_max_concurrent_requests settings of 512 & 1024 do not achieve optimal throughput for the cluster fill (write only). That workload performed better (7% for small and 12% for larger objs) with a smaller thread pool of 128. For hybrid workloads (reads, writes, stats, deletes), altering either setting had no discernable impact on throughput performance.
