It's dependent on STR only. STD works fine. DRM seems irrelevant to this
problem.

Please bare with me, as I am not really verse in English.

Yes, in mainline a kernel compiled with HZ=100 takes 4 times as long to run
lilo as it would take for a kernel compiled with HZ=1000. This problem does
not exist in mm.
Also,
hdparm -tT /dev/hda
cat /dev/hda > /dev/null
dd < /dev/hda > /dev/null
get ~30% improved throughput when setting
echo 192 > /sys/block/hda/queue/max_sectors_kb
echo 192 > /sys/block/hda/queue/read_ahead_kb
whereas anything outside 132-255 affects throughput negatively.
Is this a bug?
Thanks!
