Suppose that when Program A is run, the user CPU time is 3seconds, the elapsed wallclock time is 4 seconds, and the systemperformance is 10 MFLOP/sec. Assume that there are no otherprocesses taking any significant amount of time, and the computeris either doing calculations in the CPU, or doing I/O, but it can'tdo both at the same time. We now replace the processor with onethat runs six times faster, but doesn't affect the I/O speed. Whatwill the user CPU time, the wallclock time, and the MFLOP/secperformance be now?
