Hi,

we're trying to upgrade LS 2.4 to LS 5.0 (Solaris SPARC, both 2.4 and 5.x running java8) but we're seeing a 3x higher load with 5.x...

Here's a Grafana Graph showing an idle test server's load while running Logstash 5.x, we went back to Logstash 2.4 at approx 14:00...

Is anyone else seeing this? Any idea how to fix this?
