Really nice. A few days ago I took two of our dCache storage boxes that we use amongst other things for the LHC data and LOFAR data etc. What I did is that I have installed ocis-beta4 on one of them and I took the scripts that we have used in the past for the acceptance tests for our storage machines. Those scripts use gridftp but I have changed that to curl. I have let those two machines copy data to one another using curl. With 4 parallel reads and 4 parallel writes all running concurrently I got a throughput of about 1200MB/s writing and 900MB/s reading.
