 Description   

1) For 3.2 - Default cache size set for 60% of the RAM, we should refresh the docs
maximum of half of physical RAM or 1 gigabyte

2) Our docs should highlight the use cases when smaller wiredtiger cache produce better throughput
e.g.

  • Insert only workload
  • Running more than one instance of wired tiger on the same box

3) We can gain throughput w/ larger cache when running w/ database (Dataset) < RAM
