Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-14544 ( https://hibernate.atlassian.net/browse/HHH-14544?atlOrigin=eyJpIjoiNDVhYT... ) Re: Performance degradation observed with Hibernate 5.4.23 updating timestamps cache when a cacheable hint isn't specified ( https://hibernate.atlassian.net/browse/HHH-14544?atlOrigin=eyJpIjoiNDVhYT... ) Yes, obviously every mutation needs to invalidate certain query cache regions, which works through the timestamps cache. I guess that your default cache configuration might play a role here. I don’t know much about EHCache, but maybe answers like this can help: https://stackoverflow.com/questions/67993442/hhh90001006-missing-cachedef...
