Question about P2Pool (on Bitcoin network) : how many time must wait for the P2Pool node to adjust the difficulty ?

I have rented a 4,7 TH/s and, when it has finished, my regular 10 GH/s follow the path.
But, the difficulty stuck at 1200 (instead of 2).
I have waited 1h and no change on difficulty ...

When i restart the P2Pool node, the difficulty is reset to 1 and the P2Pool rise to 2 for the 10 GH/s like usual.

The P2Pool difficulty itself is dynamic and adjusts with each share found.

There are 2 other difficulty settings configurable by the miner:

Share difficulty: sets the actual difficulty for a miners shares. This was implemented for large miners who wanted to set share difficulty HIGHER than P2Pools actual difficulty. If set to lower than share difficulty it is ignored. It is set by adding a "/" to the end of your address followed by the difficulty number.

Sudo share difficulty: sets a sudo difficulty so your miners will submit work more often than they would at the actual difficulty. This is useful to smooth out your hash rate graph on the node. It is set by adding a "+" at the end of the miner address followed by the desired sudo difficulty.

You can set both or either one.

Regardless of your settings shares will only be accepted if they meet the minimum P2Pool difficulty.

Edit: as pointed out below I mixed up the + and /, this post is edited to be correct.

Hmm, I was under the impression that it was the other way around, i.e.:
- adding a "/" followed by the desired difficulty level to the end of the Bitcoin address would tell the miner to submit only shares above the stated "/" difficulty level, and
- adding a "+" to the end of the Bitcoin address tells the P2Pool node to always give the miner work with the stated "+" difficulty level.

Personally speaking, I have always found the "+" option to be the most useful as it forces p2pool to give a miner the specified work difficulty.

Your both absolutely right! Will edit now so it's correct, was on my cell phone and could not search the source so went from memory (or lack there of...)
