Description
It's been found that the old twitter recommendations of 100m per core up to 800m is harmful and should no longer be used.
Instead the formula used should be 1/3 or 1/4 max heap with a max of 2G. 1/3 or 1/4 is debatable and I'm open to suggestions. If I were to hazard a guess 1/3 is probably better for releases greater than 2.1.
