Compressing filesystems like jffs2 and logfs gain better compression ratio with larger blocks. Going from 4KiB to 64KiB gave somewhere around 10% benefit iirc. Testdata was a 128MiB qemu root filesystem. Granted, the same could be achieved by adding some extra code and a few bounce buffers to the filesystem. How suck a hack would perform I'd prefer not to find out, though. :) Jörn -- Write programs that do one thing and do it well. Write programs to work together.
