Yes, testing the layers should be significantly slower than just locating and parsing the XML files. How much slower, depends on the nature of the layer, where the data is, how expensive the test is (e.g., testing a remote WFS layer is likely going to be slower than verifying a local shapefile). The main question is normally... why do you need 30k layers (and growing)? Often people publish a ton of files for cases that would be solved by using a single image mosaic, or a single layer with time/elevation dimensions. There are of course also legit cases for such large number of layers, like someone acting as a service provider, and selling slices of GeoServer (workspaces) to customers on a cloud platform.
