we had once a varnish setup running containing VCL-Code with several
million lines generated by a script. Varnish was doing fine delivering
some 1000/s.

We also hat do deal with this. It took us more than an hour to compile
the vcl. Our solutions was to compile it on a backend server, copy the
.so File to the frontends and load it into the running Varnishes there.



P.S.: By the way. Later we took the data contained within the VCL and
put it into a redis db. We wrote a simple vmod to query the information
out of the database and does all required logic based on the data with
some simple lines of code. Maybe this is a better solution for you, too.
