A very wide margin indeed. Admittedly my one system and some vendor's stats arent to be construed as comprehensive- but 2 times!? The other interesting thing is that (C) with 8MB had dd showing 6.99 MB/sec (really!) but as soon as it was upgraded to 32MB throughput dropped to ~3.7 MB/sec. I have to say that the system doesnt feel any slower and conclude that it always had a throughput of 3.7. Regardless, this looks like a bug to me. Comments? /Leo
