![]() The central processing unit (CPU) of your typical computer orchestrates the math that produces the results we are seeking. ![]() ![]() To better understand this, it helps to first level-set by reviewing, at a high level the data process path because we all tend to lose sight of the basics in the bright light of new technologies. The answer is more complicated than simplistic, but there is a fundamental (and literal) bus-bridge we all must cross that consistently throttles all of our endeavors to enhance speed. Why, despite all of these enhancements, are we still on the hunt for ever better performance? Still, despite all these improvements, hunting for acceptable performance continues to occupy much of the time of those in IT (you can verify that with your friendly and frazzled local database administrator). Hard Disk Drives (HDD) have yielded much ground to Serial Advanced Technology Attachment (SATA) as well as non-volatile memory express (NVMe)-connected Solid State Drives, increasing drive I/O, and vastly decreasing latency between storage and RAM. Along with these changes, storage technology continues to improve. Memory technology has also improved in cycle and bus speed, along with overall size allowing for main system memory (random access memory, RAM) to become ever larger.
