With Faster (2) speed, according to Bui's attack speed thread:
Barrage alone with no delay: 2300%/1830ms = 1257%dps
Energy Orb: 900%/930ms = 968%dps
Energy Drain: 360%/450ms = 800%dps
Barrage alone with pre-KMS delay: 2300%/3240ms = 710%dps
I don't know post-KMS delay, so I can't tell you that. What I do know is that Barrage+Dragon Strike is supposedly the best DPS combo (without involving Orb or STrans) so this might be of interest to you:
Barrage+DStrike: (2300%+850%)/(1830ms+1080ms) = 1082%dps
Barrage+Orb: (2300%+900%)/(1830ms+930ms) = 1159%dps
An unsurprising result, since Orb is both faster than DStrike and slightly more damaging on single hit.
