Subtopic: rapid navigation for exploration, restructuring, explaining links, multiplexing 
| KMSquote: browsing is the canonical activity; must be quick, especially for large-scale hypermedia [»akscRM7_1988, OK]
| | KMSquote: speed of following links is the most important parameter for hypermedia [»akscRM7_1988, OK]
| | KMSquote: faster response time reduces mental and physical effort [»akscRM7_1988, OK]
| | KMSquote: KMS rapid navigation reduces cost of exploration; can backtrack to known frame [»akscRM7_1988, OK]
| | KMSquote: KMS rapid navigation facilitates locating place to change and restructuring [»akscRM7_1988, OK]
| | KMSquote: KMS uses time multiplexing (quick frame display) instead of space multiplexing [»akscRM7_1988, OK]

Subtopic: rapid navigation replaces scrolling and link explainers
| KMSquote: KMS browsing is quicker because it does not use scrolling [»akscRM7_1988, OK]
| | KMSquote: rapid link traversal is as practical as accessing a link explainer [»akscRM7_1988, OK]
| | KMSquote: fixed-size frames avoids scrolling which is less efficient than navigation [»akscRM7_1988, OK]

Subtopic: quarter-second response time
| KMSquote: KMS design goal of a quarter second to follow a link, may be optimal [»akscRM7_1988, OK]
| | KMSquote: qualitative difference between sub-second and multi-second response for browsing [»akscRM7_1988, OK]
| | KMSquote: ZOG improvement from 5-10 seconds to 2-3 seconds seen as major breakthrough [»akscRM7_1988, OK]
| | KMSquote: PERQ hypermedia had 0.7 or 1.5 second response time; dramatic improvement over earlier ZOG systems [»akscRM7_1988, OK]
| | KMSquote: PROMIS used specialized hardware for quarter second response time (70% of accesses) [»akscRM7_1988, OK]
| | KMSquote: ZOG with 0.05 to 0.1 sec response time was faster than needed [»akscRM7_1988, OK]
| | KMSquote: ZOG with 0.05 second response time was too fast (hard to notice new frame) [»akscRM7_1988, OK]
|
Subtopic: KMS response time
| KMSquote: KMS has 0.5 second average access time on Suns and Apollos [»akscRM7_1988, OK]
| | KMSquote: KMS usually displays new frame in less than 0.5 second [»akscRM7_1988, OK]
| | KMSquote: KMS accesses large frame (4.5 kbytes) in 0.22 seconds from cache
| | KMSquote: KMS now runs with sub-second response time (faster file systems and hardware) [»akscRM7_1988, OK]
| | KMSquote: KMS response time varies by frame size, graphics performance, disk speed [»akscRM7_1988, OK]
|
Subtopic: point-and-click interaction faster than menus
| KMSquote: 90% of user interaction in KMS is point-and-click; twice as fast as menus [»akscRM7_1988, OK]
| | KMSquote: KMS 'back' command is a mouse button on empty space; twice as fast as menu [»akscRM7_1988, OK]

Subtopic: standard format
KMSquote: KMS frames have a standard layout; quick browsing due to visual regularity
