Kafka Broker with -XX:+PerfDisableSharedMem

Hi,

After reading http://www.evanjones.ca/jvm-mmap-pause.html and
https://bugs.openjdk.java.net/browse/JDK-8076103 (alongside the linked
e-mail trail) I'm considering adding this flag when running Kafka.

I'm assuming this is safe to use and there are no unintended side effects?

Does anyone have any experience of running Kafka with this flag and seeing
a reduction in pauses?

Thanks,
Mark
