Once the buffer fills up would you expect it to work fine at 1.2MB/s? I wish I had kept the logs, but it was extremely slow (much slower than 1.2). I was copying a series of ~70MB files over and it would work fine on about the first 5 or so files before croaking. I eventually had to kill the job. -- gentoo-user@gentoo.org mailing list
