Really good twitter thread on this, with an important point regarding the staffing involved that explains why it took so long (I'd strongly recommend following this guy if you have twitter BTW):
For anyone who doesn't read all the way through the thread, apparently they are not using the world cup VAR model. The PL have a video referee and only one video assistant, plus one video operator to help. The assistant's job is to keep watching the live game while a check/review is underway in case anything else reviewable occurs. This means that the VAR has to first check for a possible penalty, then check all 4 possible forward passes to make sure there isn't a disqualifying offside. This apparently gets you to around 1m55s in this case. He then informs the referee, who then has to wait for the ball to be somewhere neutral, as if he decides to stop play, look at the monitor and then not accept the VAR's recommendation, he doesn't want to have interrupted a possible goalscoring opportunity to do so. This is what gets you to 2m10s.
Conversely in the world cup, they had a dedicated offside assistant as well as all the above staff (plus I think another assistant for something?), meaning that the offside checks can go on at the same time as the possible foul checks. I think in this situation, that probably would have roughly cut the review time in half and helped speed it up a lot.
I'm not going to mention my theory that the PL want VAR to fail, but you'd feel like they could have staffed it better if they wanted to help make it more efficient.....
