richardpl, I have already offered the explanation that the default 8% reserved for root as a cause for the missing space. Perhaps you should more carefully read the posts before taking a stab at us. Also UFS2 isn't the best solution for every scenario.
12MB/s is about the max you'll see on a 100Mbps network.
22MB/s is about normal for the read speed of a IDE hard drive
125MB/s is about the max you'll see on a 1Gbps network.
I have managed about 118MB/s copying a 350MB (yes 1.5 seconds for the transfer) file over nfs that was cached in the memory of the source host. If I copy a file from the hdd of the server then I can achieve about 50MB/s. So the hard drive is the bottleneck here (they are sATA by the way)
