Considering all the analysis we have done so far to develop new algorithms for the applications of critical processes, we can conceive the performance waterfall shown in the following image:
FSB (Front Side Bus)
The FSB is a bus that transports the data between the CPU and the outside world. When the CPU needs data from memory or from the I/O subsystem, the FSB is the highway used for that information interchange.
This performance waterfall will help us understand how we can take full advantage of modern multiprocessing. The topmost part of the waterfall represents the best performance. Hence, we lose speed as we go ...
