About this Mod

LiveProfiler is a real-time in-game performance profiler for tracking how long specific processes take to complete.
It provides low-overhead timing hooks that help identify performance bottlenecks in mods or internal systems.

This utility is primarily designed for mod developers to analyze the performance of their own code. However, it can also be used to inspect other mods that integrate with LiveProfiler, offering deeper insight into what may be impacting performance.

Frequently Asked Questions

LiveProfiler server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.5). You can switch loaders with one click in the panel.

Is LiveProfiler compatible with fabric?

LiveProfiler officially supports fabric for Minecraft 1.21.5. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with LiveProfiler – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if LiveProfiler consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
