Beta 19: List Object Questions

I often use invisible list objects in my games to store various in game data for use in things such as "lookups" and "pools" which I can pull a value/string from.

I know that the list object in MMF has been slow in the past, and hence the Internal List Object was created (though I have not used it yet). I believe I am experiencing a performance hit from using two invisible list objects which have no code for searching - only adding and deleting lines.

Could you iOS runtime developers please just check that it's not updating any of the graphical stuff even when it's invisible, or perhaps look into any way to optimize it a bit more?

And to the other testers/anyone - Does anyone have a good idea for an alternative solution if the list object is too slow in the end? I'm basically using the list object in a stack/queue fashion, with occasional insert. I add a bunch of numbers as separate lines to the list, and then I "pop" off line 0 when I need it. Comma separated numbers was one idea I was thinking about, but that might be a little cumbersome for my project.

Cheers.
