It also explains why a 10-core iMac Pro (2017) or a 12-core Mac Pro (2013) hits a CPU limit during playback and suddenly starts dropping frames, regardless of how fast the storage is. It becomes pretty clear why a NAS that can deliver up to 700 MByte/s via SMB3 to a macOS 10 Gbit client can easily become an issue.
Observing the incredibly bursty and wildly unpredictable/inefficient resource usage in terms of CPU, storage bandwidth and memory in these local iMac Pro tests is quite revealing. There is no noticeable performance difference between Metal and OpenCL. Memory usage always goes beyond 10 GB during playbackĮnabling “High Playback Quality” makes matters even worse.Storage bandwidth usage often goes beyond 1000 MB/s.CPU usage often goes beyond 80% when starting playback, and sometimes even caps out at 100%.At one point it dropped over 600 frames in a row after moving the playhead and hitting play, because the CPU hit the limit. At certain points however, even the 18 Intel Xeon cores (36 with HyperThreading) is pushed beyond its limits by Premiere Pro. Playing around with 10 two hour long HD streams of Apple ProRes 422 in multicam mode in Adobe Premiere Pro on the fastest Mac currently available on the market (as of January 2019), with media stored on its blazing fast internal SSD storage, works pretty well in general.

The fact that even an old 2015 iMac 5K with a 4-core 4GHz Intel i7 CPU and 16 GB memory is able to play the same 10 streams of media in “High Quality” both from local storage and a NAS via 10 Gbit Ethernet and SMB3, while at the same time on the same machine doing a screen recording at full 5K resolution with Telestream ScreenFlow using 1 full CPU core of the 4 (8) available.
