The default heap memory for the elasticsearch is 1GB, which is not sufficient to load the data with logstash which ends up showing "script unresponsive".  
I have a Virtual Box setup which has 4GB allocated memory, how can i increase the JVM size and to much, considering I have a dataset of about 116 mb

Thank you for getting back @dadoonet  
So if i increase RAM allocated to the Virtual box will it solve my problem?

As you have a 4gb virtualbox instance, I'd give 2gb of HEAP to elasticsearch.  
Give it a try and you will see if it's getting better or if you are having another issue.
