All of that in a single weekend? Wow!
I will say that the newest update (6.5) has a much more efficient way of writing the 'tag read' and live export data out to files. So I'm hoping that if you were to leave the tag read export on then you wont notice any lagging. As for the "copy database" option, as long as it's copying local (not out to a cloud location) then that should be pretty instant too.
