I'd be more concerned with how any server would scale to having thousands of databases running on it myself ... but, right now, my largest server is running ~165 databases, servicing 4 physical servers, and the server itself is still highly responsive. Note that the server that that database is running on runs two other instances of PostgreSQL (7.2 and 7.4), 2 of MySQL (4.0 and 4.1), one of Firebird and about 25 other "virtual servers" ... loadavg is generally <2 ... Only time I've ever really had a problem with it was when we ran Mnogosearch for the archives ... major dog on resources, since it wasn't really designed for anything by MySQL ... ---- Marc G.
