now many dosbuffers have you set for every SFS partitions?
Average suggested is 1000 dosbubbers every GB of partitions. I know sounds a lot but hey ... SFS requires it :-)
ah .. and to be sure that the dosbuffers are enough, run SFSQuery (after you have used the partition for some minutes) and look at how many caches have you missed
