About the benchmarks

The Parity client benchmarks are based on the work of Martin Holst Swende done 21 July 2018 for Constantinopole. The new benchmarks have been done for 2.1.1-beta version released 20 September 2018 as well as for master branch (branch as of 25 Oct - 5a1dc3e) with bn dependency pointing to version before and after the optimalisations by Andre Silva

If we compare pre- and post- benchmarks we see there is a significant performance boost justifying reduction of gas prices for ecmul and ecadd operations. Also, pairing is ~2.82 times faster when we compare Martin's benchmark and version 2.1.1-beta what also suggests that pairing gas cost can be reduced.

Martin's benchmark (21 Jul)
