What impact do disk block and fragment sizes have on a vinum volume? I've been benchmarking an array of three drives in striped and raid5 configurations with various stripe sizes. I've noticed that I get better results in just about every instance by passing -b 16384 -f 2048 to newfs. This doesn't make sense to me as those are the defaults for newfs if they are not specified, but looking at the disklabel after a newfs, it shows 8192/1024. Should these options really make a performance difference, and if so, how?
