Although the main use was for real-time output of 24k-bit voice I also tried it as swap and tmp under general circumstances. One result, although I don't remember the exact numbers, was that C-compiles etc were significantly improved. However, because I was using an 11/34A, the CPU speed then became the limiting factor. under heavy load conditions, the disks did in fact achieve near-zero latency.
