It's quite difficult.  If you load up one plugin, it's buffers sit in the
Processor Cache and it runs wonderfully.  It's when you run 10 plugins at
once you see the impact.

(not always 10, it depends how big your cache is etc).

My hunch is when plugins use memory bandwidth sparingly, you can run a
higher number of plugins.
