------- Comment #24 from seife@xxxxxxxxxx  2006-11-10 01:57 MST -------
maybe this helps. different machines, but not _that_ different:

piix:
root@strolchi:/# dd if=/dev/zero of=/tmp/zero bs=1M count=100 oflag=sync
100+0 records in
100+0 records out
104857600 bytes (105 MB) copied, 13,0965 s, 8,0 MB/s

ata_piix (only 10MB!):
d119:~ # dd if=/dev/zero of=/tmp/zero bs=1M count=10 oflag=sync
10+0 records in
10+0 records out
10485760 bytes (10 MB) copied, 73,1469 s, 143 kB/s

This would match the ~5 seconds pause after every RPM: 10 blocks are written,
10 sync() calls, every one of those takes ~7 seconds, and a little bit of time
to actually write the data.

Jeff, do these ~7 seconds barrier-timeout (?) on ext3 trigger something for
you?
