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.
