How to Enable Ahead-of-Time (AOT) Cache on Your Hytale Server
Hytale servers run on Java 25, which typically requires a “warm-up” period where the Just-In-Time (JIT) compiler optimizes code while the server is running. To skip this and achieve near-instant boot times, Hytale includes an Ahead-of-Time (AOT) Cache. By enabling the HytaleServer.aot pre-trained cache, your server can bypass heavy CPU tasks during startup, making reboots much faster and reducing initial lag. This guide will show you how to toggle this high-performance feature on the GGServers panel.
Step 1: Stop Your Hytale Server
Because the AOT cache changes how the Java Virtual Machine (JVM) initializes the game files at launch, this setting cannot be changed while the server is live. Access your GGServers Control Panel, select your Hytale instance, and click the Stop button. Wait for the status to show as “Offline.”

Step 2: Access Server Settings
Once the server is fully stopped, navigate to the sidebar on the left side of the panel. Click on the Server Settings button. This area allows you to manage the specific launch parameters and technical configurations of your Hytale dedicated server.

Step 3: Open the General Settings Tab
In the Server Settings menu, look for the General Settings tab. This section contains the primary toggles for server-side behavior, permissions, and advanced performance features like the AOT cache.

Step 4: Enable “Use Ahead-of-Time Cache”
Locate the box labeled Use Ahead-of-Time Cache. Simply toggle this switch to the “on” position. This will instruct the server to use the HytaleServer.aot file during the next boot sequence. The GGServers panel will automatically save your changes, so there is no need to look for a save button.

Step 5: Start Your Server
Go back to your main dashboard and click Start. You should notice a faster transition from the startup phase to the “Running” state in the console. Your Hytale server is now utilizing pre-trained optimizations for a smoother, more efficient performance!
