Emulation is slow because it is emulating a CISC processor with a RISC processor. You are better off running QEMU on your Mac than on your iPad.
Does to hard drive limitations in space might not be able to run Windows 10 on an iPad or Macbook Pro.

Under the hood, intel processors emulate a CISC processor with a RISC processor, so there’s nothing fundamentally slow about that.
Staying with the same instruction set (e.g. x86 -> x86) does help with performance though.

It’s slow because it’s emulating, period. CISC/RISC has little to do with it.
