great job andrucrypt, for Hex seeing double hash rate over "sgminer-04.R_hex"

X16r seeing about 10% at least though hard to benchmark

i'm using recommended value on OP page not had time to see if i can increase hash rate

any chance you could summarize all the options on OP, would save going through 16 pages

not 100% sure what all option do ie "--multiple-instance"

Thanks
