The 2017 I just received was a grand more and I expected to get at least as good performance (but obviously it should be better) as my Jan 2016 model but I'm having some serious issues and wonder if you think it's possible it's just the one I was shipped or if this may be a symptom of something else (for instance, the CPU% being used for tasks seems to be considerably lower on the 2017)? On some very basic tasks the 2017 is much slower: Task 1: Optimize a 2min 13sec video at 720p in iMovie Old MacBook pro: 1 min 26 sec to complete optimization/share New MacBook pro: 1 min 36 sec to complete optimization/share (for some reason CPU% for the task was only 220% on the 2017 vs 300% on the 2016) Task 2: Import a 55 min mp4 (3.78 gig) into Audacity for editing Old MacBook pro: 19 seconds New MacBook pro: 27 seconds (for some reason CPU% for the task was only 70% on the 2017 vs 100% on the 2016) Both computers were restarted before tasks were attempted and they are both running the exact same programs and have about the exact same amount of storage space % being used. I did a number of tests over and over and the results are consistently coming out like the above examples. The 2017 is clearly performing poorly in comparison to a supposedly inferior early 2016 model. Here are the specs of the two I'm using: Also, as mentioned in another thread, the SSD is not performing as stated by Apple (they claim (2200 and 3100 respectively, but results are coming out considerably lower): https://forums.macrumors.com/threads/2017-ssd-performance.2055680/ Anyone know if the culprit is simply less CPU being used by the 2017 or any other suggestions before I return it?
