I have a question about website latency for e-commerce, i've read somewhere that a one second delay in page load speed causes an average 7% drop in conversion, 11% drop in page views and 16% drop in customer satisfaction. Is this true?
How do you reduce latency and speed up content delivery?If you have any ideas on how to solve website latency problems faster, please share it with me. I would greatly appreciate it. thanks!
Minimize server-side rendering, minimize JavaScript.
Or you can always build a single-page app and then build the site with XMLHttpRequests.
But basically, avoid something like jQuery if you're not going the single-page app route. jQuery is just a giant JS IIFE and having that happen for every page request is ridiculous.

Very likely utterly false! Who produced those numbers must back them up. They are heavily dependent on the nature of the website (news, gaming, online shopping, social networking, etc), the total volume of visitors and customer expectancy (what they are accustomed with concerning the website usual performance).
Telegraph,co.uk (news website and thus following different rules from say an online shopping website) did a recent study and came up with something on the lines of a 2.6% reduction in page views per 1 second delay, for a fast website and 0.4% reduction in page views per 1 second delay for a slow website (source: here). Neither even remotely close to 11%. Even without knowing the correctness of either study, it doesn't take a genius to see that abusive numbers like 7% drop in conversion, 11% drop in page views and 16%(!!!) drop in customer satisfaction per second of delay are horribly exaggerated numbers that make absolutely no sense as soon as you just stop to think about them for a second, unless they were meant for a website that is heavily reliant on quasi real-time experience like an online game website or a market exchange website.
