Thanks for the further info. Sorry for the imprecision, but here I meant "scale" in the sense of individual Koha installations per web server rather than hits per installation. My concern is the feasibility of implementing a scheme like this on a web server which is configured to service requests for over a hundred individual Koha instances. Doesn't each individual script require it's own FastCGI daemon process per instance of Koha? Of course it would be possible to implement this on a subset of those sites, but then each step of de-homogenizing adds another cost at a different level.
