Thanks Jim, Carsten, Manuel, good hints. We’ll look
into the same setup over a 10G network. Play with slave threads, too.
Carl, can I drop an example tiff (not public, alas)? You’d be able to quickly tell how
many bits actually need to go through the pipe?
Maybe you can make one of those TIFFS available, could be anything that is not easily
recognizable. Probably even a black frame, as long as it maintains the same TIFF data
structure. That said, black compresses extremely fast anyway...
Do you know which application created these TIFFs? I have seen huge differences in
decoding speed between different bitmap formats. These bitmap load routines are usually
not speed optimized, as they are usually needed for single image access, not for video
processing. As TIFF has many different varieties nowadays, you may be very unlucky
performancewise with a certain TIFF dialect/data formatting.
