Hi there again.

All of my frames are contained within a table called 'Frames' which itself is in the addon table.

At the start of each of my modules, the table is declared as:

local f = V.Frames[module];    -- ie, in this case local f = V.Frames.Chat;

Whenever I'm writing functions though, I've always been in the habit of expressing each frame (which will be used within that function) as a local:

local cW = f.chatWindow;

I caught myself doing this 10 minutes ago, and now that I've got thinking about it, is it actually essential? The 'Frames' table (f) is already declared as a local after all. Should I just be using 'f.chatWindow' rather than 'cW'.

I know that each time I use f.chatWindow, it costs a local table lookup and that's what got me thinking. I'd much rather just reference each frame as f.xxxx to be honest, but I don't want to impact on performance unless said impact is infinitesimal.

I guess what I'm really asking is, does it make a big enough difference, performance-wise, to force me to declare them as locals as above?

Or does it really just depend on how many times I need to reference the frame in that particular function? For example, if I need to reference it 10/20/50 times, declare it as a local, whereas if it's just twice, don't bother?

Is the difference infinitesimal regardless of how many times the table value is called (within reason)?

Thank you again for any advice


Aanson.
