I&#x27;m not a Apple fan, but I find most of these tests are counting seconds and then extrapolating that to actual work time, which I don&#x27;t think actually maps as well as the author thinks.<p>The exception to this is &#x27;smart previews&#x27; test which shows a 6.5 minute difference.<p>I&#x27;ve asked the creator of fileloupe (<a href="http:&#x2F;&#x2F;www.fileloupe.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.fileloupe.com&#x2F;</a>) if his app would improve the performance of this one test. I know nothing about photos, so I don&#x27;t even know what this &#x27;smart preview&#x27; thing is...
