Web sites are just as slow to load as they were a decade ago, even though Internet speeds have gone up substantially. Slow loading impairs usability greatly. Please make your web sites load fast.
Here is an observation: This website, MulkCMS 2/Benki, loads fast unless you are logged in as an editor. If you are logged in, it loads some JavaScript for the editing controls. Now, the editing controls are pretty small, but they are code that needs to be loaded and executed.
Don’t execute too much code, OK? Best to have none at all, but if you must, keep it to a minimum, please.
