How can you say it is still the same speed. I put the calculation, speed increased from 115.0 to 117.9 (now it is 119.3) and I am getting more estimated eth per month. Use math.
Here is my ethermine dashboard pic and hashrate. Red arrow is the place that I started to use patch. See the difference in effective hashrate and average hashrate.
I think patch is working. I do not know if some share goes to some other place but definitely it increased my earnings.
Here is my calculation, I am not sure if I am correct but let me explain.
i am using 4 gtx 1070 with dual mine eth and sia. I am getting about 123 eth hashrate and 2260 Sia hashrate.
Before I use the patch. My average effective hashrate was 115.0 and estimated earnings was 1.08873 eth per month.
Now with these rates (115.0 and 1.08873) when my average hashrate increases to 117.9 I would get estimated earnings = 1.11618. (117.9*1.08873/115.0) ( if i did not have the patch)
However now after patch my ethmine dashboard shows my average effective hashrate = 117.9 and my estimated earnings = 1.13727.
As you see 1.13727 - 1.11618 = about 0.02. So it is giving you back your 2% devfee fee.
I am not sure it is coincidence but I also experience visible increase in my current effective hashrate.
So the speed is the same before and after patch. The patch does not work. He is still stealing.
