(The "U" doesn't stand for anything. Truly. Don't ask.) Did she (or you) mean "System V file system" (S5FS)? (And also, did she describe the circumstances under which it's faster - for big sequential I/O the FFS may be faster in any case - or how easy it is to tune the two file systems, or how the performance for both falls off as they get less well tuned?) >a disk block size and page size had to be equal, and a couple things that >don't come to mind right now. Basically, in my mind, she unintentionally >described the Amiga 3000UX. I assume the 3000UX supports UFS, and not just S5FS; I'm willing to put up with some performance loss in exchange for not having to keep the number "14" in mind....
