Can we make this part configurable?

Especially HighWater and LowWater connection limits:

  "Swarm": {
    "AddrFilters": null,
    "ConnMgr": {
      "GracePeriod": "20s",
      "HighWater": 900,
      "LowWater": 600,
      "Type": "basic"
    },
    "DisableBandwidthMetrics": false,
    "DisableNatPortMap": false,
    "RelayClient": {},
    "RelayService": {},
    "Transports": {
      "Multiplexers": {},
      "Network": {},
      "Security": {}
    }
  }

In the upcoming release v0.13 , a new swarm resource manager has been added.

This allows for more fine-grained resource usage control.

Modifying the number of connections and gc frequency does have a great impact on resource usage.
