To answer my own question, here&#x27;s a quote from the LuaJIT website:<p>&gt; Note: the JIT compiler is disabled for iOS, because regular iOS Apps are not allowed to generate code at runtime. You&#x27;ll only get the performance of the LuaJIT interpreter on iOS. This is still faster than plain Lua, but much slower than the JIT compiler. Please complain to Apple, not me. Or use Android. :-p
