Thanks for your valuable answer about write cache!
For object gateway, the performance is got by `swift-bench -t 64` which
uses 64 threads concurrently. Will the radosgw and http overhead be so
significant (94.5MB/s to 26MB/s for cluster1) when multiple threads are
used? Thanks in advance!

It is all the possible caches used by ceph, by the device driver, the
filesystem
Thanks for your valuable answer!
Is the write cache specific to ceph? Could you please provide some links to
the documentation about the write cache? Thanks!
Do you have any idea about the slow oss speed? Is it normal that the write
performance of object gateway is slower than that of rados
