I don't know if uBlock Origin increases this further, but even without it it's ridiculous. We measured this just for fun in a paper last year [1]:

> Compared to accepting cookies, opting out causes an additional 279 HTTP(S) requests to 25 domains, which amounts to an additional 1.2 MB / 5.8 MB of data transfer (compressed / uncompressed).

Its been an age since I looked into it. But I remember if you disabled uBlock on the page before you hit save, it updated the settings a lot faster then if it was enabled. Same thing for the Ad Choice mass optout tool (Though that would say it failed to opt out for all the companies as it couldn't send the request).
