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 jim -- All opinions expressed are mine, if you | "I will not be pushed, stamped, think otherwise, then go jump into turbid | briefed, debriefed, indexed, or radioactive waters and yell WAHOO !!! | numbered!" - #1, "The Prisoner" jbryant@tfs.net - KC5VDJ 2M, 70cm, KPC-3+ - kc5vdj@wv0t.#neks.ks.usa.noam
