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?
Cheers

It's a generic ceph configurable. It's 'admin socket'.

The ceph global config holds that variable, the osd just gets all the

defaults but it has no use for it.
