Description
With the fix that was put in place for bug #7610, rados bench appears to not be correctly respecting the -b flag when performing seq reads. In a series of tests:
4MB Writes
4MB Seq Reads
128MB Writes
128KB Seq Reads
4KB Writes
4KB Seq Reads
The reads are always 4MB verified by the optracker. rados bench itself is further reporting inaccurate per-second throughput information (based on the requested op size), though the final throughput is accurate given the actual op size (ie 4MB).
