The source files are on a jhfs+ volume. I'm disinterested in disk to disk copy. And I'm disinterested in comparing jhfs+ to other file system copies. I'm wondering how a system pushing data from memory to disk. > > You can't really control, how your file system cache is filled. > Although I must say, measuring a the whole effort a few times > consecutively provides more reliable numbers (caution: but no > disk speed measurement). I can probably control it to some degree if there isn't much free memory left, by creating a large ramdisk, that will end up as file system cache.
