A simple data pack for testing the efficiency of some function or command technique. It runs the test function recursively before the game starts to lag. It does this for 5 seconds to get a good profile. The more times it runs, the more efficient your function is.

The downloadable file contains instructions of use, so they won't be listed here. Because the data pack requires editing the test function, extract it into a regular folder before using it.

This data pack is for Java Edition 1.18.1.
