Hi,

Is there any benchmark for logstash memory requirements?

Also, does removing unused plugins from the system help in the memory footprint of the logstash application?

Thanks,  
Jaskaran

Not sure exactly what you mean by that. Most Logstash instances should do fine with a 2 GB heap which usually isn't a problem.

I don't see why removing unused plugins would help in any way.
