I tried running with the size=24G since the memory on the server is at
12GB, this reduced the iops, however the MB/s is now reduced from
2000+ MB/s, and now running on 850 MB/s
Still i think this might be a bit high?
If you do random IOs there is still a great chance of having cache hits.
This number have to be put in comparison with the network bandwidth.
If you have a 1Gbit connection ... 850 is clearly hitting lot of cache.
