I haven't yet done a full blktrace analysis yet, but the 250MB/sec speed seems to match other tests I have done with a 512 byte block size. Is it possible to do the equivalent of dd's "obs" option, to increase the output block size to 4k, 64k, or even 1M?
Sure, the -b option does that. The default is 20 (i.e., 20 x 512 = 10 KiB).
has anyone tried to make a multi-threaded version?
Not as far as I know. It's not clear that going multithreaded would be worth the hassle.
