I am running logstash 5.2 and Elasticsearch 5.1. I was actually hoping that the bottleneck might be logstash as it is a lot more easier to fix.  
But then when I run the exact same logstash configuration with

```
output
{
 null{}
}

```

The logstash process works at 36000 lines per second. So it doesnt seem to be the bottleneck here, Or is there something I might be overlooking?
