> While analysing various profiles, [@grcevski|https://github.com/grcevski] and I can came across this potential improvement.
> SortedSetDV faceting (and friends), can improve performance within tight loops by using invokevirtual (rather than invokeinterface). The C2 JIT compiler can produce slightly more optimal code in this case, and since these loops are very hot, the impact can be significant (in the order of 10-30%).
> This issue is in some ways similar to, and builds upon, prior optimisations in this area, like say LUCENE-5300 or more recently LUCENE-5309
