Oh, I wiped the bayes data and started over already once, it isn't (or
shouldn't be) that big a deal.
Disk performance: seems OK to me.
# diskinfo -t /dev/aacd0
/dev/aacd0
512 # sectorsize
73295462400 # mediasize in bytes (68G)
143155200 # mediasize in sectors
0 # stripesize
0 # stripeoffset
8910 # Cylinders according to firmware.
255 # Heads according to firmware.
63 # Sectors according to firmware.
# Disk ident.
Seek times:
Full stroke: 250 iter in 2.966242 sec = 11.865 msec
Half stroke: 250 iter in 2.126653 sec = 8.507 msec
Quarter stroke: 500 iter in 3.616484 sec = 7.233 msec
Short forward: 400 iter in 1.540087 sec = 3.850 msec
Short backward: 400 iter in 1.104617 sec = 2.762 msec
Seq outer: 2048 iter in 0.546351 sec = 0.267 msec
Seq inner: 2048 iter in 0.726598 sec = 0.355 msec
Transfer rates:
outside: 102400 kbytes in 2.103472 sec = 48681 kbytes/sec
middle: 102400 kbytes in 2.300709 sec = 44508 kbytes/sec
inside: 102400 kbytes in 3.192841 sec = 32072 kbytes/sec
nothing amazing, but nothing unexpectedly bad either.
