[jira] [Commented] (CASSANDRA-8762) Check if JNA Native gives good performance gain over Unsafe

    [ https://issues.apache.org/jira/browse/CASSANDRA-8762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14312126#comment-14312126 ]

-------------------------------------

Do you want to give this a spin, [~snazy], once you're done with your current crop of jemalloc tests?

>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8762
>             Project: Cassandra
>          Issue Type: Improvement
>          Components: Core
>            Reporter: Robert Stupp
>            Priority: Minor
>
> As noted in CASSANDRA-8714, Unsafe has some invocation overhead compared to JNI which is used by JNA.
> This ticket is to check whether it's worth to rewrite the invocations from Unsafe to Native - i.e. NativeCell et al
