Working with Lua in Libgdx - Android NDK

Ok so I’ve read an interesting article that said it is possible to integrate Lua with Libgdx using AndroLua(includes Lua and LuaJava). Now, I’ve searched a little bit on this topic and some people say it is advised not to use Lua with Libgdx(Android, specifically) because it can slow down the all thing.

Now, I ask you guys, does this integration really result in a slow performance, or is it just happens with native languages, such as C/C++?

I would like to hear from people who have already worked with AndroLua and Android NDK
