These Parity client benchmarks were run to evaluate the optimizations made to the Parity bn
pairing library (link here)
By comparing pre- and post- benchmarks there is a significant improvement to the speed of multiple bilinear pairings that merits a reduction in the gas schedule.
The new benchmarks were run on branches that are currently outstanding pull requests into the Parity client (openethereum/parity-ethereum#10624) and the BN library (paritytech/bn#14).
The previous benchmarks were computed on 25 Oct 2018
