A file server may be single- or multi-threaded. It takes 5 msec to get a request, dispatch it, and do the remaining processing if the data needed are in the block cache. If a disk operation is needed (25% of the time), then it takes an additional 35 msec. Assume that there are sufficient block-cached requests in the multi-threaded case. How many requests/second can the single and multi-threaded servers handle?
