IBExpert (usually like any other third-party tool) is running the backup through the Services API, which directly invokes/executes the backup on the server. Check out the -se switch of gbak. This should give you similar performance. Possible IBExpert also dismisses garbage collection on the source database during backup. The equivalent setting for gbak is the -g switch.
