Re: [ceph-users] Ceph Dumpling/Firefly/Hammer SSD/Memstore performance comparison

[Mark Nelson <mnelson@redhat.com>]

Hi Stephen,

It's a benchmark automation tool we wrote that builds a ceph cluster and 
then runs benchmarks against it.  It's still pretty rough (no real error 
checking,  no documentation, etc).  We have some partners that are 
interested in using it too and I'd like to make it useful for the 
community so we're going to try to make it a bit more accessible.

cbt is here:

https://github.com/ceph/ceph-tools/tree/master/cbt

We've also been using it to prototype nightly performance testing of 
firefly and master for the last month or two on some of our lab nodes. 
The cron job and test suites are here:
