iostat while doing a remote copy using WinSCP. WinSCP is reporting a ~8MB/s transfer rate.
iostat reports a 2.37MB/s read rate.
How does that make sense?
Every 13.0s: iostat -m /dev/sdb1 Fri Apr 1 19:22:38 2011 Linux 2.6.35-27-generic (moabdemo) 04/01/2011 _x86_64_ (1 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 3.26 0.00 11.25 45.07 0.00 40.42 Device: tps MB_read/s MB_wrtn/s MB_read MB_wrtn sdb1 66.74 2.37 0.01 3050 18
And every minute or so the MB/s rate has been increasing from an initial .04 to it's current level.
