Did you try .
I periodically switch between pools just to distribute hash power. None of the pool "Getting Started" mention fixed diff, but i have used fixed diff with irdpool.ru, ird.cashpool.us and irdpool tk and var diff with the other pools.
. works with irdpool.ru, ird.cashpool.us and irdpool tk
I would have suggested keeping the same format for irdpool.fr just for consistency but "+" works fine too
I would have tried inserting a period first, except I saw that the French pool used + as a separator instead (I will refrain from making the typical joke about the French here... So... Difficult... Though...). Also, it usually takes a few hours before a pending balance starts to show up and I didn't want to waste a bunch of time by choosing the wrong separator.
As for why I asked about it here rather than email the pool owner directly, I thought an answer to my question would be of interest to others. I know many feel the same way I do about the totally dysfunctional vardiff strategy usually implemented on Cryptonote pools and it is only by complaining about it loudly and often that anything will ever get done - after all, there was a reason you implemented fixed diff, no?
You are right. Default vardiff config does not work properly. But it is possible to optimize it. I am currently trying to optimize irdpool.eu.
Could you point your miner to irdpool.eu and tell me what do you think of my configuration?
Thanks!
Sure, I'm trying something else out right now but I'll be able to switch over to irdpool.eu within the next 30-45 minutes. My ping time to your pool is 115ms which is basically the same as to irdpool.fr and so not ideal, but still workable at a reasonably high difficulty.
