配置信息：
使用 2个万兆网卡的RGW主机，并用OSPF做高可用和负载均衡。 Ceph OSD集群 有21Node （万兆网卡+ 12个4T SATA机械硬盘）
测试VM配置：
使用在使用VXLAN协议构建的VPC网络内的8个4核8G的VM作为cosbench driver。 使用 128个cosbench work同时执行测试，文件块大小（4M-10M）。
测试场景和结果：
| ratio throughput | ratio throughput | ratio throughput | ratio throughput | |||||
| read | 80% 2.04GB/s | 20% 268.98 MB/s | 99% 2.34GB/s | 1% 8.8MB/s | ||||
| write | 20% 511.94MB/s | 80% 919.69MB/s | 1% 20.62MB/s | 99% 967.05MB/s |
结论： RGW读能跑满2个RGW主机的万兆网卡，RGW写1GB左右，达到RGW集群顺序写上限（增加RGW主机或在主机上部署多个RGW进程或许对提升写有帮助）。
