Is there a reason why you can't combine both loops to make it easier on the CPU?

function TDButton_DestroyAllOverlays()
    local frame;
    for key, frame in pairs(TDButton_Frames) do
        frame:GetParent().tdOverlays = nil;
        frame:ClearAllPoints();
        frame:Hide();
        frame:SetParent(UIParent);
        frame.width = nil;
        frame.height = nil;
 
        tinsert(TDButton_FramePool, frame);
        TDButton_Frames[key] = nil;
    end
end
