Noedit: If the CPU for the server literally can't keep up, the server application will hang until the CPU is free again. This causes the 'Lag' notification to show up until the server isn't hung up. Due to this, all you need to know for actual server load is your current network and CPU usage. The server application can only utilize one core of your CPU, so if you have a quad-core CPU Blockland will hang up at 25% usage.
