Performance of jBOD
Graeme Wallace 2013-10-02, 23:36
We notice that we get a lot higher performance from Kafka up until the
point where disk reads are taking place. (which is to be expected as its
reading from filesystem cache).

However, given that we have 12x7200rpm SATA disks configured as jBOD - what
sort of disk read performance should i see reported by dstat when things
are running flat out ?

I'm seeing 250-340Mb sustained.
