Hi, I posted about SCSI disk performance difference(three times) between 19980222-SNAP and 19971006-SNAP. It turned out to be the FAILSAFE option made the difference. It slows SCSI disk access down significantly. Thanks to Geoff Buckingham and John Dyson, I could dig into a little deeper. I noticed that MAX_START is now hardcoded to 32, which used to be (MAX_TARGET + 7 * SCSI_NCR_DFLT_TAGS) in sys/pci/ncr.c. Is this going to be this way from now on? Or is it anything to do with CAM? So that it will be resolved differently? It is a little annoying everytime I have to patch sys/pci/ncr.c.
