Depending on your used adblock, I'd guess it is the bottleneck. Plugins running in the browser are not made for this. If you are using browser plugin-based adblocking, try to disable that temporarily for testing, and exchange it with some host-based solution, for instance this https://github.com/StevenBlack/hosts https://github.com/StevenBlack/hosts no matter which OS your are on. Then see if it feels faster. If you are already doing it this way, forget what I wrote :-)
