It is an interesting question, but I think that it is not restricted to
Emacs or Org. Without going through a software profiling exercise, it is
just trying to shoot in the dark. In your case, you'll have a set of
relatively large files that will take some time to process. This will
cause the CPU to be bound during that time. Being that emacs is single
threaded, it's only one core that gets bound.

I run Emacs on different platforms, but most of my development is done
on ARM (A pogo plug running Arch).  Things happen a bit slower, but it
is not unusable. The biggest factor on these systems is that their I/O 
performance is not great, but it only matters when the system is
executing a lot of processes that that affects the overall system load. 
I would not say that it is the type, but the speed and the factors that 
contribute your system load.

This only affects amount of available memory. Unless you are loading
files that are larger than 2 Gigabytes, it does not matter.

> - faster I/O (through HDD->SSD or even faster SSD)

Only if the system is in high I/O utilization. When the system is
relatively idle, it really does not matter being that it's dedicated to
the CPU. So... in this specific case in Emacs, it is the CPU speed that has the
largest impact on the overall performance. 


My 2 cents.
