I have a 6 node es cluster and trying to run two instances of logstash against it.
Both piping into stdin, hosts => set with all nodes, and with default 4 workers and they return me 492s instantly.
If I set workers to 1 they're good however getting poor indexing speed. And adding another two instances with single workers makes ES screaming again
Any tips would be appreciated. I don't think previous pipeline was doing this bad?
