Unfortunately, in this case, yes, you should be concerned. Changing the author or the title can take a second per book, and seldom takes less than 1/4 second. 1000 books -- 250 to 1000 seconds, or some 4 to 16 minutes. In your scenario that could be in excess of 1/2 hour to flop the names then flop them back.
In addition, because of operating system caching, there are inflection points in the times where things suddenly get slower. Where those points are depends on the about of free memory on the machine. What this means is that there is no guarantee that 2000 books takes twice as long as 1000 books. It could be three times as long.
