Feature/graph equal optim

According to the tests it gives a 1% performance gain compared to version/4.5 branch for a single property, however it seems that for all properties main branch performance dominates, version/4.5 does not seem to improve on it for all properties...

❯ cat summary-main.json
{
  "main":{
    "InMemoryAverage": 762823.41,
    "InMemory_AllAverage": 185975.2
  }, 
  "graph":{
    "InMemoryAverage": 875464.62,
    "InMemory_AllAverage": 174252.81
  },
  "4.5": {
    "InMemoryAverage": 866540.76,
    "InMemory_AllAverage": 171910.55
  }
} 

graph branch compared to version/4.5: 
for a single property:
(875464-866540)/866540*100% = 1.03%

for all properties:
(174252-171910)/174252*100% = 1.34%

@justadreamer a better test would be a single property from each of the components available rather than all properties which will be more random.
