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 ? _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
