As a random datapoint that might or might not be related. In the
last year or so I was pontificating about how much better SCSI
was that IDE/ATA to my boss. I then did some benchmarks on my
(CURRENT) system and discovered that an old 10Gig 7.5krpm UDMA33
disk significantly out perform some Seagate Cheatah LVD 10krpm
disks.

In supplemental testing (advised by Peter Jeremy) the disk has
been able to transfer(read) 25 mbytes/sec - sufficient to declare it
not the bottleneck.
Additional testing will happen, but dump is by far the prime
suspect.

Last time I looked, ahc(4) was still under GIANT.

I noticed that. Is there any sentiment for pulling it free?
And how much would that help?
