Oops, I didn't get the "readahead" option description quite right in the last post. The default read ahead is 1, which does result in "rsize * 2", since there is the read + 1 readahead. "rsize * 16" would actually be for the option "readahead=15" and for "readahead=16" the calculation would be "rsize * 17". However, the example was otherwise ok, I think? rick
