According to the email here, PerformanceInspector is supposed to replace the old data shown at the bottom of the pages. These also included LUA logs, so it would make sense to also include that information in this module.
@Krinkle I was specifically asking about the visible data, such as the table with the CPU time and the lua logs. This bug was created when the logs had vanished because of the email linked in the description. They then reappeared, which made the bug less important. I would like to know how will we be able to access the Lua logs in the future.
