A few questions:
- When has the system gone down? We're only aware of two instances since August 1 when there has been a mining server restart to release new features, and in both cases the downtime lasted less than two minutes. Given how "uptime" is a big votegetter in the latest poll, I want to find out if there is something that isn't being detected by our monitoring system.
- It was the case before three days ago that equihash profitability was affected by orphaned ZCash blocks. The blocks were caused by high CPU usage that occurred when we needed to unshield ZCash balances. Are the profitability numbers for equihash from before or after the last three days?
- Which coins are going into error that cause losses?
You should not penalize miners for orphans if they are using PPS. Prohashing is the only pool that does this from what I've seen.
Unfortunately, the orphan rate on most coins is very high. For Digibytes, it's usually around 4% or 6%, because the blocks come so fast when it becomes profitable to mine them. If we didn't consider orphan rates, then we would not mine the correct coins and end up with a net loss.
The other thing I noticed with the profitability statistics is that people tend to leave the pool despite profitability not having changed. For example, yesterday's profitability was the same as that of the day before, and we proved the system was more profitable than Nicehash that day, but there was less hashrate yesterday. Maybe the cause was an unseen error with disconnects, which is why I want to find out the answer to these questions.
