For each test file the size is 4KB. Network connection is 1Gb. But the bandwidth never got full, it's about only 70 - 80 Mb at peak. And all servers' cpu/mem usage are low. Thanks.

Hi, What is the average size of the objects? And your network condition? Maybe the bottleneck of performance is not Swift, but the network or other things.

But our application design requires 3000 PUT requests per second. So how to improve swift's performance to match the requirement?
