Yes!! After Big Sur update, my MacBook Air 2020 and iMac 2015 are running extremely slow! Everything takes a long time to open!
Also, my iPhone is running slower as well after the update. I have no clue what Apple did or if they are just slacking, but I suggest they use their half a trillion dollars in reserve to fix this!
