Hi @RAM_NATHAN,

Increasing the heap size as you have done is the right thing to do. In terms of adding a node it really depends. There are some considerations listed in this [old topic](https://discuss.elastic.co/t/how-many-nodes-should-an-elasticsearch-cluster-have/227674) that could help you decide. There's also some further advice on choices of nodes in the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/high-availability-cluster-small-clusters.html) that can help too.

Hope that helps!
