For UseMMappedIO only lowest bits of each octet are meaningful now, other are reserved. So, if you want to turn on mmaped IO for both thubmnail reader and raw reader you need 0000000100000001 binary or 257 (decimal) anyway, Mmaped IO is (slightly) faster only on very fast media like 4xNVME SSD in RAID0 (Intel VROC). On slower media the difference is negligible.
