[JBoss JIRA] (ISPN-8422) Investigate removal of hashCode from memory block and rely solely on equals

by William Burns (JIRA)

William Burns created ISPN-8422: ----------------------------------- Summary: Investigate removal of hashCode from memory block and rely solely on equals Key: ISPN-8422 URL: https://issues.jboss.org/browse/ISPN-8422 Project: Infinispan Issue Type: Sub-task Reporter: William Burns Assignee: William Burns Fix For: 9.2.0.Alpha2 We could remove the hashCode 4 bytes taking up space in the allocated memory block. Currently this is only used for eviction, maybe instead we could write a VInt that says which offset of locks to use. In majority of cases <= 64 cores this will result in saving 3 bytes per entry. -- This message was sent by Atlassian JIRA (v7.5.0#75005)

[JBoss JIRA] (ISPN-8409) Change off heap eviction to store everything in same allocated memory block

[JBoss JIRA] (ISPN-8420) Reuse eviction sizing when memory based eviction is enabled.

by William Burns (JIRA)

William Burns created ISPN-8420: ----------------------------------- Summary: Reuse eviction sizing when memory based eviction is enabled. Key: ISPN-8420 URL: https://issues.jboss.org/browse/ISPN-8420 Project: Infinispan Issue Type: Sub-task Reporter: William Burns Currently entryRemoved and entryReplaced calculate the size for the entry twice. This is not needed when memory based eviction is enabled as it is the same value. Having a way to pass that down would help reduce reads on a write operation. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
