[JIRA] (HHH-13979) Performance with JCache/EhCache v3 is three times slower than with old ehcache

by Alex Roytman (JIRA)

Alex Roytman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-13979 ( https://hibernate.atlassian.net/browse/HHH-13979?atlOrigin=eyJpIjoiYTQzZj... ) Re: Performance with JCache/EhCache v3 is three times slower than with old ehcache ( https://hibernate.atlassian.net/browse/HHH-13979?atlOrigin=eyJpIjoiYTQzZj... ) I did go through with debugger and I see that hibernate's cache entry with its disassembled state (array fields) is being serialized to a byte buffer before being stored in cache. I would have thought that cache entry should be stored in the cache as is without serialization ( 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!

[JIRA] (HHH-13979) Performance with JCache/EhCache v3 is three times slower than with old ehcache

by Alex Roytman (JIRA)

Alex Roytman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-13979 ( https://hibernate.atlassian.net/browse/HHH-13979?atlOrigin=eyJpIjoiYmM2YT... ) Re: Performance with JCache/EhCache v3 is three times slower than with old ehcache ( https://hibernate.atlassian.net/browse/HHH-13979?atlOrigin=eyJpIjoiYmM2YT... ) I have a feel it could be in serialization code. I wonder when you put entity into secondary cache I assume you extract its state and thus it can be stored by reference not by value. I wonder if going through JCache API to initialize caches it may by default create by value cache causing unnecessary serialization/deserialization of keys and values all the time. I could not find a declarative way for ehcache to force by-reference model and their docs say that their heap default is by reference but when going through JCache interfaces it defaults to by-value unless set to by-reference during cache initialization. Maybe it is what's happening?
