A swap on my system is a hard disk write.  That takes time.  Whereas not 
swapping takes 0 time.  Measurable?  I suppose it can be done but I 
don't have the hooks into the OS to do it.

The real issue of course is why did swapping begin?  It began when 
memory was tiny compared to the programs and their memory allocations, 
plus of course VM.

But today RAM is massive compared to the memory demand (in most cases) 
and swap isn't necessary for most users if they stuff the memory in 
there as I have.
