Comment 10 for bug 381300

Again: this time I simultaneously wrote two 3GB files on top af an ext3 fs on top of a 8GB pendrive, ...

------------------ noop ------------------
elapsed: 11' 52", high iowait but no system slowdown, it's quite good.
avg-cpu: %user %nice %system %iowait %steal %idle
                8.01 0.00 6.61 83.31 0.00 2.65
------------------ anticipatory ------------------
elapsed: 11' 56", high iowait but no system slowdown, it's quite good.
avg-cpu: %user %nice %system %iowait %steal %idle
                6.51 0.00 6.01 82.96 0.00 5.16
------------------ deadline ------------------
elapsed: 11' 58", high iowait but no system slowdown, it's quite good.
avg-cpu: %user %nice %system %iowait %steal %idle
                6.87 0.02 7.58 79.64 0.00 6.54
------------------ cfq ------------------
elapsed: 19' 50", visible system slowdown with many app, but it's still usable.
avg-cpu: %user %nice %system %iowait %steal %idle
                5.44 0.00 6.39 82.24 0.00 6.30
-------------------------------------------

This time in iostat I can't see significative difference between cases,
but the system become slow and unresponsive with cfq...

Now, I'm much more disappointed...
