Large increase in job switching after new release

Hi,

first I like to say I like the new features and graphs!

However I've noticed a huge increase in the job switching resulting in suboptimal mining for me, possible after the new release. I've first noticed this behaviour around 10:30 Amsterdam time (8:30 UTC).

I have just started mining here a couple of weeks ago and used the "r=..." parameter to tweak my work restart delay. Currently I don't notice much difference between no "r" parameter at all, "r=5" or "r=10".

Any idea what is going on? I really liked this pool the last couple of weeks and I hope I can keep mining here.

Best,
Maznoz

There might be some emergent behavior from the change we made last night to make block times more accurate on networks that switch frequently.

For now, I temporarily disabled that feature, so the behavior of the mining server will be identical to what it was before the release. All other features are unaffected. If the switches continue, it may be that switching so often is actually the correct choice because the time lost in switching is still better than mining litecoins.

Let me know what happens now.

Thanks for the fast response. I will keep you updated here.

So far the miner performance seems unaffected, making it less likely to have been caused by the update.

Performance has increased a lot now, so I agree that it is related to current coin conditions.

Is there any way to exclude a set of coins?

No, there's only a way to include coins. Excluding coins is tricky, because that means that we need to come up with a formula to determine how much such exclusions should be penalized for bringing down the pool's profitability.

I think we can do more work on this issue during the evening or this weekend to optimize it, now that we have the code deployed. Changes to a few configuration values may be all that is necessary.

unbelievable just as things were going well one of my titans dies 30 min ago, I think its the raspberry pi module as I cant get any video off of it.
