COSBench is a benchmarking tool to measure the performance of Cloud Object Storage services. Object storage is an emerging technology that is different from traditional file systems (e.g., NFS) or block device systems (e.g., iSCSI).

COSBench now supports OpenStack* Swift, Amazon* S3, Amplidata v2.3, 2.5 and 3.1, Scality*, Ceph, CDMI, Google* Cloud Storage, Aliyun OSS as well as custom adaptors.
