Can someone please give me a mining tip based on their experience? I get home and see 4 accepted and 5 rejected. My scantime is 5 and expiry is 25. Should I up my expiry to something like 30 would that help to lessen rejected rate but maybe less accepted too?
this is for solomining
Are you using "--failover-only" ?
Anyway this is the best explanation I've found for expiry and scantime:
Expiry is the upper bound on how many seconds after getting work we consider a share from it stale, and it defaults to 120 seconds. That means every two minutes it will double check the current work to see if it is expired. Stratum should make this unnecessary, because it should notify the client when new work is available, but in the case where stratum doesn't notify, expiry will cause it to pick up the new work after a maximum of 2 minutes. If you're seeing lots of stales, lowering this should help, because you'll pick up the new work more frequently, at the cost of bandwidth overhead.
Scan-time is the upper bound on time spent scanning current work in seconds, and it default to -1, which is forever. This could be used to prevent work on stale blocks in the case of a network outage where new work isn't avaiable: By setting it to 5 minutes, if the miner can't get new work in 5 minutes, it'll stop looking and save you the electricity. It defaults to -1 so that you'll never stop looking, even in the case of stale work.
By setting each of these to 1 and 1, you're going for the insanity wolf level of difficulty: Every 1 second, go see if there's new work, and if you can't verify the work for 1 second, stop scanning.
Sensible settings are x0.25 - x0.5 your block confirmation time for expiry, and -1 for scan time: That ensure that you check for work on average 2-4 times before you actually expect to see new work on average, even though with stratum you don't need to, and you'll keep looking even in the case that the current work couldn't be verified to be current.
