HI,

our Logstash does a lot of calculations and is getting stuck under a lot of info. The question is how to fix this, one way we saw was to raise the Xms and Xmx. Is there a way to give the logstash to work with more threads?

Hi,  
Thanks, you for the reply, in which config file is this by default?

The pipeline worker setting is configured in logstash.yml or on the command line.
