I want to get opinion on increasing the number of replicas vs increasing machine size.  
Configuration: 1 node 1 shard architecture and I want to double the load on my Elasticsearch cluster.

Increasing replicas:  
If I make replicas double, load can also be doubled but indexing speed will go down.

Increasing machine size:  
But what if I make machine size double, can the load be doubled with same query latency.  
What changes do I need to make it accept double load.
