I have a question about setting up a pool, I'm using z-nomp and now I'm trying to understand what parameters are best for finding blocks. I'm currently using this setup

paymentProcessing": {
        "enabled": true,
        "paymentMode": "prop",
        "_comment_paymentMode":"prop, pplnt",
        "paymentInterval": 600,
        "minimumPayment": 1,
        "maxBlocksPerPayment": 4,

      "ports": {
        "3032": {
            "tls":false,
            "diff": 8.497924805,
            "varDiff": {
                "minDiff": 0.04,
                "maxDiff": 32,
                "targetTime": 15,
                "retargetTime": 60,
                "variancePercent": 30
            }
        }
    },
   
   "walletInterval": 5
   
   I use p2p and blocknotify script, rpc calls are disabled.
From what I see now on my server cpu load is 100% while it is doing shielding operation. I want to ask - it it possible that while it working under heavy load I can miss blocks? How minimize cpu load? If anyone is willing to help - please contact me through telegram or through e-mail.
