[RadosGW] Performance for Concurrency Connections

[Kuo Hugo <tonytkdk@xxxxxxxxx>]

Hi folks, 

I'm doing some performance benchmark for RadosGW. 

My benchmark tools is ssbench & swift-bench. 

I found that the best reqs/sec performance is on concurrency 100. 

32 CPU threads on RadosGW

24 CPU threads on each Rados Node

The Network is all 10Gb

For 1KB object PUT : 

Concurrency-50   : 538 reqs/sec

Concurrency-100 : 1159.1 reqs/sec

Concurrency-200 : 502.5 reqs/sec

Concurrency-500 : 204 reqs/sec

Concurrency-1000 : 153 reqs/sec

I think the bottleneck is on RadosGW. How to improve it for high concurrency cases ? 

Appreciate
