ccminer-skunk-krnlx is slower than SP-mod because of the default intensity. Insert "-i 25" into the code and do the comparison. The reported rate of krnlx is faster than sp-mod. Anyway, the fluctuation of the rate we see on the pool is kinda like stale shares in ETH mining. It needs time to get the avg.
my hash rate get increased as well. I will test it for few hours to see how it is.
