What makes menus (generally) so slow?

It's possible some menu transitions use some sort of instruction the JIT falls back to interpreter on, but I'm not aware of any notable cases.

I saw a lot of this happening.

It s not important, but it s there. If you play many games with fps on screen you will notice in initial home screen on simple game menus like mario party saga, fps fall to 10 or 20 for a second whileavigating through them. Not sure if real wii behaves like that. Also not sure if cache textures has something to do since they are simply 2d menus.

It s totally irrelevant and doesnt affect gameplay at all. But im curious too to see why this happen. Wonder f this abrupt fps changes could cause some online netplay desync.
