Runs with skip_recording = false non-chainbase trx hashed_unique multi-index. Also removed the hashed_unique index and only had index on expired, no difference in performance.

Percentage increase of skip_recording = false for mapped mode.
(7.56+7.56+7.61)/3 - (6.24+6.28+6.28)/3 / (7.56+7.56+7.61)/3 =
(7.58 - 6.27) / 7.58 = .17 = 17% increase in time
