I'm not sure I understand the question. You can start FCGIs any way
you want. The spawner is just a shortcut for starting many FCGIs at
once and the spinner is a insurance against fallen FCGIs. How does
either have any effect on RAM or start-up time?
The spinner process is running all the time, and because it has loaded
and initialized the whole Rails environment (boot.rb etc.) it uses a lot
of RAM. The same goes for the spawner process. It is started every
#{interval} seconds, and because it loads the Rails environment every
time - this can put a considerable load on a small server. IMO neither
spinner nor spawner do really need the Rails environment, all they do is
to call external scripts.
