After loading 11,467 layers (and ~15K SLD’s) into JDBCConfig, Geoserver responsiveness (particularly the layers list in the admin interface) is initially fine. But after a restart, or a configuration/catalog reload, it often takes 2+ minutes to display the layers list.

The slowdown seems to occur at this line in the code, for the method ConfigDatabase.count:
https://github.com/geoserver/geoserver/blob/master/src/community/jdbcconfig/src/main/java/org/geoserver/jdbcconfig/internal/ConfigDatabase.java#232

which I believe is trying to get the count of all layers in the catalog. During the iteration, ConfigDatabase.getId is called for apparently every item in the catalog:
https://github.com/geoserver/geoserver/blob/master/src/community/jdbcconfig/src/main/java/org/geoserver/jdbcconfig/internal/ConfigDatabase.java#747

The two filters being used in the count method are an IncludeFilter and IsEqualToImpl filter (screenshot attached).
