I'm getting about 600-1000% CPU usage on a 12 core machine running logstash @6000 eps. Although I wonder what is this 100% usage on 1 cpu with 25% user and 75% system. Seems to be related to all the java thread running. Is this normal? Is there a way to distribute this load across other CPUs?

Can you provide your config?
What version?

Sure, this is the same config as [Overcome 2600 msg/seconds with Logstash/Filebeat](https://discuss.elastic.co/t/overcome-2600-msg-seconds-with-logstash-filebeat/50626)
Input is filebeat, filter with kv (mostly) and output to redis.
