I've been fooling with some disk performance testing with bonnie, and I threw mfs into the mix for fun. Everything but the mfs had disk had soft updates enabled - and it shows. They all had pretty much the same performance numbers for character-at-a-time writes as they did for block writes. MFS didn't. Which makes me wonder - is it possible to enable soft updates on an MFS file system? Is there any point in doing so? Second question - can vinum be configured to buy more performance, rather than making large partitions? In particular, could I buy two EIDE drives for about the cost of one SCSI drive of that size, hang them off separate EIDE controllers, and get performance closer to that of the SCSI drive?
