How does a setup make swift have the capability of 3000 TPS, for the
average size 500KB of files? What architecture, hardware, network etc
will be expected? Thanks for any suggestion.

Hi Pangj,
First, make sure you have an updated version of swift-bench. There was a
bug where it was relying on python-swiftclient to setup eventlet, but when
eventlet was removed from swiftclient, that caused swift-bench to not run
requests concurrently.
There are quite a few things that should

Hi, pangj
While putting small objects, the bottleneck will not be the network
bandwidth, and the server's cpu/mem will be low. It will be a matter of
inode and cache. You can check the iowait of your storage node server
and it may be a "filesystem" problem. As a estimate of the performance
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.
