----------------------------------------
Assignee: Andrew Mashenkov
> GridKernalContextImpl::isDaemon creates contention on system properties access
> ------------------------------------------------------------------------------
>
> Key: IGNITE-7508
> URL: https://issues.apache.org/jira/browse/IGNITE-7508
> Project: Ignite
> Issue Type: Bug
> Components: general
> Reporter: Stanislav Lukyanov
> Assignee: Andrew Mashenkov
> Priority: Major
>
> GridKernalContextImpl::isDaemon reads system property IGNITE_DAEMON on every
> call, leading to contention on the system properties lock. The lock is shown
> as contended in the Java Mission Control analysis of a JFR recording of the
> IgnitePutGetBenchmark.
> The fix would be to cache IGNITE_DAEMON value (e.g. in IgniteUtils) since it
> isn't supposed to be changed during the JVM's lifetime anyway.
