My very informal benchmark (windows 7, SSD, RamMAP tool to clear OS file cache before each run):

1. twiddling windows flags made no difference to speed
2. TIFFOpenfile with mode "ru" i.e. disabling memory mapping, was 3 times

slower than with default flag "r"

So, my conclusion is that memory mapping is the way to go for performance.

I assume you mean "rm"? I don't think "u" has any meaning.
