You tell: > You should define the mix first, under rw, using total percentage for reads and writes, and then specify the random/sequential break in each direction under pct_random. I understand that but it's not correct. ------- [global] rw=randrw rwmixread=70 <= 70% randread and 30% randwrite for others percentage_random=12,8 <= 12% seqread, 8% seqwrite ------- Could you provide an example, please?
