"The server is lagging" is not one problem; it is four honest causes you can check from your own seat. Start from the graphs on your server's page in the panel, then work down this list: view distance, plugin load, world activity, and plain sizing.

First read: your own graphs

Your server's page in the panel carries CPU and RAM graphs, and they outrank every rule of thumb on this page, including ours, because they measure your world. Read them first. A graph pinned high while players play says load is the story. A graph sitting low while players still feel lag says raw capacity is not the story, and one of the causes below is. Nothing here replaces the graphs, because nothing here can measure your server the way they do.

Check 1: view distance

View distance sets how much world the server keeps live around each player. Raise it and the server keeps more chunks live per player: more chunk work and more of whatever happens around every player, every second. Lower is lighter.

The setting lives in server.properties at your server's file root. Open it in the file manager, find view-distance , drop the number a step or two, save, and restart to apply. Most players never miss the two chunks a lighter setting gives up; your graphs are the check that the drop mattered.

Check 2: plugin load

Two parts: fit and count.

• Fit: a plugin built for a different game version or platform can stall the startup, spam the console with errors, or drag the running server down. The console is where its errors show.
• Count: one lean plugin is small; a wall of them is not.

Watch the console during startup: plugins that load show up there, and the ones in trouble name themselves. A plugin that never shows its listing or prints an error during startup is a suspect, and its version fit is the first recheck. The full install and verify routine is the plugin article in Related reading.

Check 3: heavy world activity

Mob farms that run all day, big redstone switching constantly, a huge explored map: these are your world's habits, they scale with players online, and they show up in the graphs. If the graphs climb right when the busy parts of the world are working, this is the cause, and the honest lever is the world's habits, not the plan.

Check 4: plain sizing

Our published advisory: figure about 4 vanilla players for every 1 GB of server RAM. For modded, halve it. Those are advisories, not caps; real use swings in both directions. If your player count, mod load, or view distance sits past the advisory for your RAM, and the graphs agree, sizing is the likely story. The full sheet prints on the plans page , every tier with its RAM and price on one table.

Still stuck after this list: open a ticket from your account with what you tried and what the console printed, and a person reads it with you.
