I can understand that you need ads to survive, but your website is insane.
I disabled the built-in Enhanced Tracking Protection in Firefox (81.0b8) and reloaded your website, but I had to abort after close to two minutes, with 530 (!) requests and 11.32 MB transferred. This is nothing but extreme, and obviously one of the (if not the only) reasons as to why the website feels slow. With the tracking protection enabled, the website stops loading after 20 seconds, with 61 requests and 7.46 MB transferred.
Compare this to my own community: 1.91 seconds, 42 requests, and 2.47 MB transferred. Or the Invision Community forums: 3.32 seconds, 52 requests, and 3.35 MB transferred.
I'm probably not in your preferred audience, but I would never in my life use your website with the amount of ads and trackers used.
Disclaimer: I'm currently using a 4G LTE connection, but the number of requests and MB transferred would be the same with high speed Internet.
