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@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
