I am not sure this will help Shantur. But you could try running 'watch cat
/proc/meminfo' during a benchmark run.
You might be able to spo

Hi Paul,
Thanks for replying to my query.
I am not sure if the benchmark is overloading the cluster as 3 out of
5 runs the benchmark goes around 37K IOPS and suddenly for the
problematic runs it drops to 0 IOPS for a couple of minutes and then
resumes. This is a test cluster so nothing else is run
Hi,
blocked requests are just requests that took longer than 30 seconds to
complete, this just means your cluster is completely overloaded by the
benchmark.
Also, OSD 2 might be slower than your other OSDs.
