Well, CMS usually cause a lot of lag. Why: because they tend to show off a collapsed bunch of malarkey called JavaScript, which entices the user to use, suggesting simple use. In most cases, JavaScript is pretty much useless. I came across websites that looked good, but that even gave my latest gastrointestinal upset. The reason is that JavaScript was used for almost everyone. This slows down significantly, regardless of whether you use a CMS or copy your own web page.
A simple design rule that I learned: use JavaSript when necessary for the task. Never, never when he doesnโt add any functionality or does it only when you are studying and want to check a thing and, naturally, when your customers keep knocking on your door because they need animated pop-ups, scrolling parallax and the like.
There are times when you need JS, even for eyecandy, but on too many pages this is too much. Result: people will love your web page, where your photo gallery page will not take 15 seconds to display a new image, or the scroll speed will make you think that the Internet was โfasterโ in the early 1990s ...
