KawPow algo low hashrate compared to other mining software..
**Describe the bug**
Hey there guys!
I'm not sure if this is the correct place to open this issue but I'l post here due to the activity of this project. (Please let me know if I should open it somewhere else.)

I have a few GPUS and amongst them there is one GTX 1060 OC PNY 6GB (No user OC), this GPU based on kryptex (https://www.kryptex.org/en/hardware/nvidia-gtx-1060-6gb) should be yelding about 11MH/s and weirdly it was only producing around 7.4x\~7.8x MH/s as seen on XMR-Workers (https://github.com/coolhaircut/xmr-workers - CUDA now supported):

So then I thought, hey... its a PNY... what are you expecting from it eh?!
Upon placing it in my test rig, I have used T-Rex and KawpowMiner to compare results and was when Ive noticed that the other miners have at least 2MH/s difference!
So, I ask myself... is it CUDA optimization or is it their mining algo implementation?!

I have also played with threads, blocks, bfactor and bsleep but I only managed to increase the rate to 8MH/s but that was it...

Results:
XMRig: 7.4\~7.8MH/s
T-Rex: 9.90\~9.99MH/s
KawpowMiner: 9.73\~9.86MH/s

I really wanted to continue using XMRig as Ive liked the way it works and even contributed to XMR-Workers with CUDA support (Too bad I havent got any ATI laying around..)

**To Reproduce**
Use XMRig on Kawpow, then use T-Rex(https://github.com/trexminer/T-Rex/releases) or Kawpowminer(https://github.com/RavenCommunity/kawpowminer) to compare results

**Expected behavior**
XMRig to have a hashrate similar to other mining software.

**Required data**
 - Miner log as text or screenshot

 - Config file or command line (without wallets)
 Kawpow CFG untouched:
 `        "kawpow": [
            {
                "index": 0,
                "threads": 256,
                "blocks": 20480,
                "bfactor": 0,
                "bsleep": 0,
                "affinity": -1
            }
        ],

 - OS: [e.g. Windows]
 Tested on both: Ubuntu Server 18.04 (x64) and Ubuntu Desktop 18.04 (x64)
