just another observation...

iozone shows drastic reductions in throughput on a SCSI-2 2G
barracuda...  i was getting approximately 5.5-6.5 M/S on both read and
write under 2.1-R...

now i get approximately 2.5 M/S write and 4.5-5.5 M/S read...

options		AHC_TAGENABLE              # experimental

is the 2.1-R config and gives the above results...

options 	AHC_ALLOW_MEMIO

seems to give no improvement...

currently running 2.2.2-R
