My iPad Pro M2 takes around 30 seconds to solve it in Safari, while my Mac Studio solves it in about 3 seconds using 449% logical CPUs. It really makes no sense

My iPad Pro M2 takes around 30 seconds to solve it in Safari, while my Mac Studio solves it in about 3 seconds using 449% logical CPUs. It really makes no sense. Interesting how much slower it is than native - could it be protections against things such as crypto mining?
