It depends on what you want printed to chat.

This is the d() function:

function d(...)    
    for i = 1, select("#", ...) do
        local value = select(i, ...)
        if(type(value) == "table")
        then
            EmitTable(value)
        else
            EmitMessage(tostring (value))
        end
    end
end

If all you want to print is simple text, then just use CHAT_SYSTEM:AddMessage("text").

Granted, you shouldn't be looking for 1 nanosecond optimizations. Good coding practices aside, only worry about optimizing when doing heavy calculations or frequent updates.
