Comment 8 for bug 381300

On my notebook (fujitsu-siemens amilopro v3505):

writing large file on a pendrive:

------------------ noop ------------------

elapsed: 19' 31"

avg-cpu: %user %nice %system %iowait %steal %idle
           4.77 0.00 14.39 49.16 0.00 35.82

no slowdown, all good...

------------------ anticipatory ------------------

elapsed: 19' 24"

avg-cpu: %user %nice %system %iowait %steal %idle
           4.04 0.00 12.87 53.54 0.00 31.16

minor slodown moving windows or writing to the internal disk.

------------------ deadline ------------------

elapsed: 19' 44"

avg-cpu: %user %nice %system %iowait %steal %idle
           6.76 0.00 10.38 46.15 0.00 37.59

minor slodown moving windows or writing to the internal disk.

------------------ cfq ------------------

Elapsed: 27' 35"

avg-cpu: %user %nice %system %iowait %steal %idle
           0.59 0.00 10.12 88.76 0.00 1.29

everything is slow, and some time locked...

-------------------------------------------

What I can say is that at home, yesterday, I never
seen the iowait over 40%.

The fact that it does not happen on every pc explain why
cfq is the default...
