Alex Roytman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMjVhOWVjNDA4... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-13979?atlOrigin=eyJpIjoiMjVhOW... ) HHH-13979 ( https://hibernate.atlassian.net/browse/HHH-13979?atlOrigin=eyJpIjoiMjVhOW... ) Performance with JCache/EhCache v3 is three times slower than with old ehcache ( https://hibernate.atlassian.net/browse/HHH-13979?atlOrigin=eyJpIjoiMjVhOW... ) Issue Type: Bug Affects Versions: 5.4.14 Assignee: Unassigned Components: hibernate-ehcache Created: 23/Apr/2020 16:11 PM Environment: Hibernate is 5.4.14 EhCache 3.8.1 JDK 8 Priority: Major Reporter: Alex Roytman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) 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 <config xmlns:xsi = 'http://www.w3.org/2001/XMLSchema-instance' xmlns= 'http://www.ehcache.org/v3' xmlns:jsr107 = 'http://www.ehcache.org/v3/jsr107' xsi:schemaLocation=" http://www.ehcache.org/v3 http://www.ehcache.org/schema/ehcache-core-3.8.xsd http://www.ehcache.org/v3/jsr107 http://www.ehcache.org/schema/ehcache-107-ext-3.8.xsd"> <service> <jsr107:defaults default-template= "defaultCache" enable-management= "false" enable-statistics= "false" > </jsr107:defaults> </service> <cache-template name= "defaultCache" > <expiry> <ttl unit= "minutes" > 60 </ttl> </expiry> <heap unit= "entries" > 20000 </heap> </cache-template> <cache alias= "default-update-timestamps-region" > <expiry> <ttl unit= "minutes" > 600 </ttl> </expiry> <heap unit= "entries" > 50000 </heap> </cache> </config> I would appreciate any input Thank you, Alex ( https://hibernate.atlassian.net/browse/HHH-13979#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-13979#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
