------------------------------------------
Summary: 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
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.
