Just to follow up here is the same test on the non-server node (remote CFS). Again don't trust the numbers too much because technically I'm suppose to use >2GB filesize and perform the test on a completely idle cluster. However this quick test shows remote CFS isn't that much slower, only about 10% performance hit (random write).
