What it does

Timing hooks in LiveProfiler record how long chosen processes take to complete, reporting the cost in real time while the game runs. The overhead of each hook is kept low so the measurements themselves do not distort what is measured. Its main audience is mod developers, who can time parts of their own code to find bottlenecks. Other mods can also connect to LiveProfiler and expose their internal systems to it. The mod is client-side only, so only the player's game needs it. It is open source under the GNU General Public License v3.0 or later and is published for 1.21.5 only.
