Thanks for your answer — that was also our thoughts. It's pretty
impressive to see how far we can go with varnish, as well as how many
connections it can handle without a single leap :).

Regarding the GCC: I think it uses it (default debian install) — is
there a way to make the compilation a bit faster? Our vcl is big (really
big)… and it takes some minutes to compile each time. Yes. Minutes. [khof].
