Thomas Mueller commented on OAK-3343: ------------------------------------- http://svn.apache.org/r1702259 (trunk; adding a disabled performance test) I noticed the Guava cache we use also uses a segment mechanism, same as the LIRS cache. My tests show that the LIRS cache is almost always faster than the Guava cache (average 30%). The default settings for the LIRS cache is 16 segments, and for the Guava cache also 16. So I consider this closed. > LIRS Cache: investigate concurrency behavior > -------------------------------------------- > > Key: OAK-3343 > URL: https://issues.apache.org/jira/browse/OAK-3343 > Project: Jackrabbit Oak > Issue Type: Bug > Components: cache, core > Reporter: Thomas Mueller > Assignee: Thomas Mueller > Fix For: 1.3.7 > > > I have a report that the LIRS cache (in combination with the persistent > cache) does not perform well when using 50 threads that concurrently access > it. The Guava cache might not be affected (as much). > I would like to investigate, with a simple test case, what is the behavior of > the LIRS and Guava cache with highly concurrent use cases, in combination > with a cache loader. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
