optimize miners (xmrig) and xmrig-proxy config
Hi, I'm using xmrig miners (about 38 cpu miners) on different networks.
Previously I used for all the xmrig miners, the pool "pool.supportxmr.com:3333" (I know the pool set automatically the most suitable level of difficulty for the single miner)

The hash-power of my 38 miners goes from 60hs (the poorest) to 290hs (the best).
I see that if I don't set "custom-diff": 5000, on xmrig-proxy, all miners take a very high level of difficulty.
After I set "custom-diff": 5000, all miner receve from the xmrig-proxy the difficulty level of 5000.

With "nicehash" support set to "enable" on xmrig miner side, I don't see any difference. I read that it should be activated when mining through xmrig-proxy
Or I should use "nicehash" support only with "custom-diff": 0 ??

The actual xmrig-proxy level difficulty receved from pool is 53100.


Since I have miners with different hashpower, what are the optimal settings to adopt? I have noticed that since I have set "custom-diff": 5000 on xmrig-proxy, the "Invalid shares" have drastically decreased.
