im development a client-server application and i have a performance dude. I have a Db whit 10 tables. The server could attend a lot of clients at the same time and every client use this tables to insert rows. Every client is independent of the rest (dont share information). I want to know if is convenient create one schema for every user (10 tables from schema) or every users sharing the same schema (only 10 tables) Every user could insert a lot of rows per table.
