I'm testing this miner about a week on few rigs, but have mixed feelings. Ammount of info in console = great. Readability of these info = very bad (I wrote about it few days ago). Reported hashrate about 1-2 Mh/s higher than Claymore. But. This is just a teoretical number and what matters are accepted shares. And with Phoenix I have less accepted shares last days then in Claymore.
Sometimes it has weird behavior - autostarting miner after reboot gives me sometimes very high accept share time, about twice as high as normal. Quitting miner and starting it again solve this sometimes.
On rig started restarting itself, after running few minutes of Phoenix. (NVidia GPUs)
Tried a lot of testing, -mi settings, but I still don't have a feeling, it is the best miner. Time will show... Keep up good work, idea is nice. Thanks
You are seeing that higher share rate afyer you start the miner or reboot because you are connecting to the pool which resets you the base difficulty for that port you have selected. So say you mine for 10 hours you are on the 2G difficulty but over that last 10 hours the pool raised your difficulty to 4G because your rig(s) are faster, hense you solve less ahres but each solve is worth more heft.
Back to the restart and reboot, when the miner 1st starts up and you see that flurry of shares is because you are set by the pool at the lowest difficulty, either by the port you chose or all connect to one port and the pool auto adjusts. regardless, every pool will auto adjust your difficulty.
So just because you get 100 shares in the first 30 minutes and 50 shares the next 2 hours its becasue your difficuty was increased. You see this with phoenix when it submits a share, it will say the difficulty found and what your pool has you set at. It will be low when you 1st connect and higher when you have been mining longer. just remember as you go up in difficulty you solve less shares but the value of those higher difficulty shares are worth more, percentage wise in the PPLNS or whatever your pool is doing to share.
