Both pools adjust the difficulty up to 10000H no matter which port is being used, which is bad.
Correction. After connecting on 7777 the diff gets ramped up like this: 10000H, 20000H, 40000H, 80000H, 100001H.
This is where it remains and it is much too high. Maybe nice because low server load. But very inefficient mining.
If you are using auto-diff it must be such that shares get submitted every few seconds.
At 100001H literally minutes pass without a share getting submitted, then a new round starts and all the work was wasted.
Next round eventually the same or with some luck one of those ultra high diff shares is found.
Mostly it isn't and the work expires.
When connecting on 3333 it starts at 100H, then 200H, 400H, 800H, 1600H, 3200H, 6400H, 12800H, 25600H, 51200H and then goes to the famous 100001H and remains there.
It seems this auto-diff is not able to adjust down. It only goes up to the max.
I remember that until yesterday this wasn't the case. It went only to 10000H and remained there, which was good for my setup.
Mining at 100001H makes no sense. Not with high-end GPUs and even less so with CPUs.
