I use 2K because I (and others) put in so much hard work : to fix all the little niggling bugs in the VM system related to partial : page validation and, damn it, I intend to use those features! At the other end of the spectrum, 32M [sic] and 64M [sic] disks work well with -b 4096 -f 512 -c 10 But I tend to do what phk has done with the large -c flags on my insanely-sized, rediculously-cheap XXG IDE drives.
