Which card are you using? Funakoshi-miner is much faster on 1080 read what kron79 has to say
Exactly on 1080rig I get ~325 from EWBF and ~300 with your miner. It's only PL55 and EWBF still make 46.5sol/s average. With PL90-100 it can be much faster.
I have tested with 1080ti and confirm it's slower EWBF # 15%
