I have tried dstm v0.5.4 and v0.5.5 for several weeks on my two rigs with Acrefawn autostart premium script (which BTW is great, saved me many sols). On one rig (6 x 1070 Asus Dual) I got on average 2800 sols. Comparing to EWBF it is almost 100 sols more. On second rig with mixed configuration (Palit 1060 , Strix 1070, Strix 1080Ti, Palit 1070) 1850 sols - no difference comparing to EWBF. My experience confirms that dstm is the best on gtx 1070. Initially I was very pleased with additional sols but frequent crashes forced me to revert to EWBF. I got crashes even without OC. Crashes are no problem with Acrefawn script but they reduce the sols performance advantage. I like dstm and it is promising but wait for further stability improvements and better sols performance.
