I feel like it's an issue we will never have on the project I'm currently working on, all requests have a noticeable delay. I guess there's too many layers on the back-end. And maybe some requests are totally not optimised (like doing 20 select 1 elt instead of select 20 elts). And maybe there's no enough caching. Or maybe the thing we're caching are not those that matter… But first we still have to migrate off Internet Explorer (or at least support another browser).
