[Koha-devel] Possible IRC tutorial nginx and FastCGI

[Fouts, Clay]

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.
