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

I was wondering what the 'CBT' tool is ? Google is useless for that acronym...
Thanks!

Hi All,
I wrote up a short document describing some tests I ran recently to look at
how SSD backed OSD performance has changed across our LTS releases. This is
just looking at RADOS performance and not RBD or RGW. It also doesn't offer
any real explanations regarding the results. It's just a first high level
step toward understanding some of the behaviors folks on the mailing list
have reported over the last couple of releases. I hope you find it useful.
Mark
