Hi Ben, I've tried out the new RB IO on a problem with a "merged" .xdr file that is 301MB --- previously I read this data in as many separate .xdr files each of size 130kB. In serial, it took about 22 seconds to do the read in the merged case (i.e. RBEvaluation::read_in_vectors() took 22 seconds) vs. about 42 seconds in the "separated" case. So it gives a 2x speedup, which is very helpful indeed. Though I recall that a 30x speedup didn't seem out of the question --- are there possibly some parameters (block sizes, etc, like before?) that I can try tweaking to see if we can speed up the merged case further?
