I'm still not sure that the following text in the manual page is accurate: These values tend to produce better performance than the defaults for file systems larger than about 5 gigabytes. So far, my Postmark benchmarks on filesystems as small as 128M all show performance improvements using 16k:2k, given an average file size of 2k or more. It seems to me that the decision on what block:frag sizes to use has much more to do with file sizes than with filesystem sizes. Matt, do you have any comments on the manual page text quoted above?
