Description
After upgrading to Hammer and moving from apache to civetweb. We
started seeing high PUT latency in the order of 2 sec for every PUT
request. The GET request latency looks good.
Attaching the radosgw logs for a single request. The ceph.conf has the
following configuration for civetweb.
[client.radosgw.gateway]
rgw frontends = civetweb port=5632
Further investion reveled the call to get_data() at
https://github.com/ceph/ceph/blob/hammer/src/rgw/rgw_op.cc#L1786 is
taking 2 sec to respond. The cluster is on Hammer 94.2 release.
