It has been really frustrating watching the frontend-web evolve. Take Jira for example, the platform is written in Java yet all my time is spent waiting for all the widgets to jiggle their way into existence. No matter how fast your server is, if you have to do 10-20 network requests to hydrate your frontend architecture the network time alone is going ruin your perceived performance. Your server could deliver sub 5ms response times, with 50ms Time to First Byte on the initial request, and it would still feel like wobbly molasses. The JVM is the least of their worries.
