Could someone run timings at different block sizes and pick one that gives most of the speed benefit without being huge?
Note that this interface will probably be run on a pipe and different block sizes will have a different impact on different operating systems (and even between versions). I remember there was a paper on the drastic differences in speed between the pipe handling on Windows 2000 and XP for different block sizes. Maybe someone can recollect where that paper was...
