Hi.

Another idea would be to fork off some threads to do the splitting in parallel. If the disk drivers and/or drives are brilliant, the reads should get ordered such that you pay a minimum penalty for rotational latency. The idea is that if there are two reads to be done on the same cylinder, then the one rotationally closest to the head will go first.
