 Well, not much. The relevant file [30logglobal.lua](https://github.com/Yonaba/30log/blob/master/30logglobal.lua) features the same source as the original [30log.lua](https://github.com/Yonaba/30log/blob/master/30log.lua), excepts that it sets a global function named `class`.
 This is convenient for some embed Lua implementations such as [Codea](http://twolivesleft.com/Codea/).
 
+##Benchmark
+
+Performance tests featuring class creations, instantiation and such have been included.
+You can run these test with the following command with Lua from the root folder, passing to the test script the actual implementation to be tested.
+
+```lua
+lua tests\benchmark\tests.lua 30log
+````
