View versus simulation
View distance controls terrain sent to players. Simulation distance controls the nearby area where entities are updated. Increase either only after checking the workload.

Build a server.properties starter for Vanilla or Paper. Choose the settings, understand what they do, and download a file you can review.
01 / Set the experience
For a standalone Java server using Vanilla or Paper. Select the basics, review the output, and merge the settings into your existing file.
View distance controls terrain sent to players. Simulation distance controls the nearby area where entities are updated. Increase either only after checking the workload.
The output keeps online-mode enabled and remote console access disabled. A Velocity backend needs its own forwarding and firewall setup; this is not a proxy configuration.
Save a copy of your current file. Merge the selected settings and test after restarting. Use the Spark analyzer to compare performance.
Settings reference: Paper server.properties documentation. Older server versions may support different options.

No. It controls how many players can connect. Performance depends on hardware, software and the world workload. Use the RAM calculator for an initial memory estimate and a Spark capture to investigate real load.
View distance controls the terrain sent to players. Simulation distance controls the area where entities are updated. Raising these settings can increase server work, so compare captures under similar player activity.
This generator is for standalone servers and keeps online-mode enabled. Proxy backends need version-appropriate forwarding, authentication and network access controls. Follow the proxy documentation for that setup instead.
The generator escapes special characters and Unicode for the properties format. The preview shows the human-readable text; the escaped file preserves it when the server reads the property.
