Can someone clarify this? > * Developers believe performance is speed. It isn’t. Performance is a difference in measure between two (or more) competing qualities, the performance gap measured in either duration or frequency. Maybe I'm a dummy, but if someone says "make a fast webapp", I'll be doing things like reducing requests, optimizing queries, making things smaller, using the right data structures, manipulating data in a fast and/or memory efficient way. This should result in lower loads, more stability, better availability, etc, so also "more performance". I do think of it as lots of focus on speed since, for the most part, I'm measuring how long it takes for a function/query/etc to run. Happy to check out some articles/keyword suggestions.
