Best method - Importing 50x10gb CSV files into Elasticsearch on GCE

Elastic Stack Elasticsearch
4

I did try running it straight from the GCE VM. I was actually getting slower indexing rates (~300-400/sec).
I am using out of the box configurations. I'm assuming I should still see better results.

@javadevmtl I like the idea of disabling replicas. I'm going to try that. Here is my logstash config. See anything wrong?

input {
file {
path => "/elasticsearch/data.csv"
start_position => "beginning"
type => "data"
}
}
filter {
csv{
separator => "|"
}
}
output {

 elasticsearch {
     action => "index"
     host => "localhost"
     port => "9200"
     index => "indextest-data1" 
     workers => 2
     #cluster => "elasticsearch-cluster"
    protocol => "http"
cluster => "elasticsearch-cluster"
 }

 #stdout { codec => json }

}

Thanks for the help so far.
