Hi Wei Zhao,
I've used ycsb for mongodb on rbd testing before. It worked fine and
was pretty straightforward to run. The only real concern I had was that
many of the default workloads used a zipfian distribution for reads.
This basically meant reads were entirely coming from cache and didn't
really test the storage system at all. I ended up creating some my own
profiles so that we could test both the default zipfian read setup and
using a random read distribution as well. I hadn't heard about nor have
used the YCSB S3 tests, but I would be very interested in giving it a
try. Cosbench can be a bit heavy if you only need to run a couple of
simple tests and have other tools for the test orchestration and data
visualization.

Hi:
I found cosbench is a very convenient tool for benchmaring rgw. But
when I read papers , I found YCSB tool,
https://github.com/brianfrankcooper/YCSB/tree/master/s3 . It seems
that this is used for test cloud service , and seems a right tool for
our service . Has anyone tried this tool ? How is it compared to
cosbench ?
