The number of locks that are needing to be acquired will consistently increase the amount of time it takes to backup the database as you add schemas and objects. This applies to whether or not you are running a single dump per schema or a global dump with -Fc. I agree with the other participants in this thread that it makes more sense for you to use -Fc but your speed isn't going to change all that much overall. Joshua D.
