I read most of the DOS 6.0 manual around 1994. This was the era of memory management. Computers had 640k of conventional memory despite my PC having 4M of total ram. Every TSR you could extract out to high or extended memory would have a massive impact on the performance of high demand applications (like all my important applications from Lucas Arts...). I managed to get mouse, soundcard, video, and other drivers loaded and still have 580+K of free conventional memory.
Now I design web scale server architectures capable of handling hundreds of requests per second with five 9's of uptime (for a few years anyway), and that memory management, from back when I was a tween, is still one of my proudest technological achievements. Thanks DOS manual!
