mmap() is still fantastic for mostly-read datasets. If you serialize and queue your writes, and 'replay' them with a little bit of heuristics about page alignments you can also help the kernel a lot with the flushing job. I've discovered mmap 25 years ago on SunOS, I haven't outgrown it yet -- it has served me well over the years, and I expect it will continue to do so ;-)
