On the past couple years I’ve been noticing that the web community (specially front-end devs) started to become more interested and to care way more about performance, trying to make applications load and execute as fast as possible. I think it was mostly influenced by Steve Souders High Performance Website and Yahoo’s Performance Rules.
Performance is a very important topic, which can directly influence the success/fail of an application, but I do believe that some people are getting things wrong and exaggerating a little bit (including myself)… – Of course everybody wants their applications to run and load as fast as possible but “optimizing” things without need is simply wrong. A common quote about performance explain this:
“We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified” – Donald Knuth
