I love the idea of this pool, and have been using it with ~17-18MH/s for the last 2 days. I don't have any time to manage my miners these days, so this is a perfect solution.
That being said, the issues listed above are a problem which I've also noticed.
My setup looks something like this:
7970s mining @ 800KH/s
7970s mining @ 740KH/s
7950s mining at 655~680 KH/s
Everything works great for the most part, except when the pool switches to low difficulty and or low block time coins. Right now, the pool is mining what I assume to be Litecoins because of the 54.9M difficulty level. When we're mining high difficulty coins like this, everything is fine and all of my cards are able to submit shares @ 512 difficulty since we're working on those 54.9M difficulty blocks for long enough. In this case, 512 difficulty shares are perfect.
The problems start when we switch to less than 50~100k difficulty or so coins, from what I've noticed. 512 difficulty shares simply take too long to calculate, and new blocks are discovered before 90% of us have a chance to even submit a single share. This means that we are (mostly) all burning electricity and wasting time for absolutely nothing, as only the 10% (in this made up example) of the pools users are managing to submit shares/blocks while the rest of us get nothing due to the 512 difficulty setting.
The solution to this is very simple, thankfully. We need lower difficulty, 128 or max 256 difficulty shares. Unfortunately, this causes problems for the pool operator since it's increasing the work load on his server.
A better, but harder solution which may or may not be possible for the server:
Coin difficulty >500k = 512 share difficulty
Coin difficulty >200k = 256 share difficulty
Coin difficulty >100k = 128 share difficulty
Coin difficulty >50k = 64 share difficulty
Coin difficulty <50k = 32 share difficulty
I think this would optimize profits for everyone,
including the pool operator who would end up collecting more fees off of our higher individual profits received from submitting low difficulty shares on super fast coins which are currently escaping us.
Thankfully I've got quick mining cards. I can only imagine how much worse the problem must be for people mining on 6 and 5 series cards.
h20, you've been doing a stand up job managing and tweaking the pool. You deserve more than all the profits you've been making so far from the 3% fee. Lower the share difficulty, and you'll have just that.
Thanks for running this awesome pool, and I really hope this small problem gets resolved when you have the time so that myself and others can continue mining with you.
