You could try using a TSynEdit instead of a TListBox: some years ago I 
switched from TMemo to TSynEdit to do some logging in a similar (though 
I add lines instead of assigning the complete text, also, I delete the 
oldest line when there are 5000 lines) because I found that, under 
windows, TSynEdit is an order of magnitude (or more) faster than TMemo.
No difference under linux though, and maybe it's no longer true nowadays.
