I think I had it on my Intel 13950HX laptop as well, but also haven't taken much notice. It's one of those things I accepted, perhaps putting it down to heavy scene with some particular feature (I once found out for example a scene where single object with symmetry modifier applied to poly select, or something like that, caused 15 minute Max opening, and 4 minutes of Corona Precomputation, just weird, and it was purely because of that symmetry mod combo).
It's so hard to diagnose these things that I gave up trying to do most of the time unless it's extreme, like that symmetry bullshit, since that annoyed me with every render start, but I only close scene few times a day so I didn't bother investigating.
