Nope, but I would be interested in the throughput you get when you pipe dd if=/dev/rsd0g to /dev/null and dev/zero to ttcp (withou gzip), simultaneously. Do you see any difference in the disk throughput when stopping ttcp?
And same question applies if you reduce bs (128m from 1g for example) -- Jean-Yves Migeon
