thanks 1) I'm sure there's no asok socket filer for the radosgw in my RadosGW host. 2) The rgw_thread_pool_size was set to 200 in my ceph.conf. So that the radosgw is using the value now generally. 3) If so, the tweaking of rgw_thread_pool_size value from 100->200 was not help for improve the performance of concurrency connection. 4) I'm considering to put some research on apache's configurations. 5) Do ya have a similar benchmark run for high concurrency connections before?
