However, the A15x4_A7x4 model is running quit slow for launching the kernel, about 1minute to showing the kernel booting screen. Whereas A15x1 model is launching quite fast, just in several seconds.
This is in general not very surprising, since the A15x4_A7x4 model is doing eight times as much work (it has eight CPUs to emulate)... If your use case allows you to hold some of the CPUs in reset rather than letting them run, this should make things a bit faster. Also for multi-CPU models make sure you have lots of RAM in your host system and that you are not starting to swap.
