The main loop is basically a select() call under linux. A convenient one.

This means that each main loop iteration calls select with a bunch of
file descriptors to listen (X server socket and other sources). If one
of them has data the handler for this source is called, otherwise there
is a timeout that triggers the timeout events and other timed events.

So the performance should be equally to a simple select call reduced
a bit with overhead of the main loop context handling.

Note: I'm not a glib specialist.
