I have no experience running RT with NGNIX (only installed it as
proof-of-concept once), but from what I can remember, it's serving all
the static files directly (if you follow the documentation, you don't
even need Apache anymore) and maybe also cached data.
I sincerely doubt you'd hit a scalabilty-wall in NGINX before running
out of CPU for the spawn-fcgi perl processes. Adding varnish to the mix
looks to me like a wasted effort (if you serve RT over SSL, you'd need
NGINX in front of it, again, because varnish does not do SSL at all).
