The cache by default has 100 hard references plus a free amount of soft references that can be freed when there is GC pressure. The number of hard references is tunable, see https://docs.geoserver.org/stable/en/user/configuration/globalsettings.html#feature-type-cache-size The capabilities transformer needs to perform some checks, so it iterates over all the feature types, the first time actually opening connections, the other times (hopefully) hitting the cache. Mind, calls to "reset" and "reload" (status page, REST API) wipe out the cache completely. Cheers Andrea == GeoServer Professional Services from the experts!
