And so little is delivered with the 2.5mb. Worrying more that so much traffic is bot traffic, and bloating sites becomes significantly wasted resources.
I just rewrote a wordpress site made 7 years ago for a client as a static site. Replaced the index.html 4 image parallax with a 3 image css slider (mobile, desktop versions) and added 5 languages for the 5 pages the site has.
complete website now weighs 15.9 MB - 14.5 MB is images (395 including responsive versions plus fallback twin). The index page now has a total of 558KB while the same page in the old WP site clocks 21MB - (5.7MB for the 4 images) which it loads in steps 8MB - then 17MB and jumping to final 21MB when I move the cursor from the reload button over to the page.
