We migrated from Hibernate 4.3.8 to 5.4.14 and migrated from old ehcache 2 to jcache with ehcache 3 based secondary cache. we noticed application being terrible slow. A simple test of bulk reading our entities and iterating over their collections showed following:
with no secondary caching - 10 sec
with old ehcache provider - 13 sec
with new jcache/ehcache 3 - 32 sec
with Apache JCS - 28 sec
Hibernate is 5.4.14, EhCache 3.8.1
my default cache config is consistent for both. in case of jcache it is
{code:xml}
<config
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
xmlns='http://www.ehcache.org/v3'
xmlns:jsr107='http://www.ehcache.org/v3/jsr107'

{code}
I would appreciate any input
Thank you,
