Find the Bottleneck in my Video Editing System

[Doug Ferguson]

Hello,

I built the system below after some heavy research and now have a very big computer. I own a video production company and use Adobe's Creative Cloud 2015 Premiere and After Effects on a daily basis. The system, I feel, should be faster than it is but I don't know what testing tools or what to look for in the one's I've tried to determine where my system lacks. I'm currently working on a project where I have to edit 12 streams of HD video from various camera formats. See the specs below and any advice on what components I might swap out or configuration I could try to make life better.

My computer:

CPU: Intel Core i7-3930K 3.2GHz 6-Core Processor
CPU Cooler: Corsair H100i GTX 70.7 CFM Liquid CPU Cooler
Motherboard: Asus P9X79 WS SSI CEB LGA2011 Motherboard
Memory: G.Skill Ripjaws Z Series 64GB (8 x 8GB) DDR3-2133 Memory (64 Gb)
Video Card: NVIDIA GeForce GTX 970 4GB Video Card
Power Supply: Corsair Professional 1050W 80+ Gold Certified Semi-Modular ATX Power Supply

My Storage is configured as such:

C: Drive (Programs Only):
1 x Samsung 850 EVO-Series 500GB 2.5" Solid State Drive

P: Drive (Video Projects, and all the Library files like pictures, music, documents...)
8 x Hitachi Ultrastar 7K3000 3TB 3.5" 7200RPM Internal Hard Drive
in a Raid 30 connected to an Areca ARC-1882

Z: Drive (Cache Drive for Premiere's cache previews and temp files and for exporting videos)
2 x Samsung 850 EVO-Series 500GB 2.5" Solid State Drive
in a Raid 0 connected to an Areca ARC-1882

I have other drives for backups and archive storage but those don't effect the editing workflow. Premiere just doesn't seem to perform like it should. I have spent hours on the phone with them trying different versions to try to make it edit properly.

Thanks for your help.

Doug

Also, perhaps you might want to clean for dust or check for temps.

I would open resource monitor in Windows and work as normal, then check resource monitor after it slows down and if your CPU, RAM or disk usage is consistently at 100% that's probably the bottleneck.

EDIT: It also could be network usage however this seems less likely to me.

I have a 10Gb intel card connected to a 10Gb Netgear switch so I don't think it's the network.

Network's irrelevant.

Yes, I am trying to edit all the streams together in a multi-cam sequence. I don't have any effects or color grading at this point, just the raw files. I have many different camera formats:
Sony EX3 and EX1 (.MP4)
Canon DSLR's (.mov)
Other cameras with (.mts)

I did a Crystal Disk Mark test on the drives.
The Production drive (Raid 30 with 8 3Tb Hitachi drives)
Sequential Read (Q= 32,T= 1) : 675.546 MB/s
Sequential Write (Q= 32,T= 1) : 1060.333 MB/s
Random Read 4KiB (Q= 32,T= 1) : 49.762 MB/s
Random Write 4KiB (Q= 32,T= 1) : 78.501 MB/s
Sequential Read (T= 1) : 1100.054 MB/s
Sequential Write (T= 1) : 287.328 MB/s
Random Read 4KiB (Q= 1,T= 1) : 77.592 MB/s
Random Write 4KiB (Q= 1,T= 1) : 3.264 MB/s

Here is the Cache Drive SSD as a Pass Through Disk:
Sequential Read (Q= 32,T= 1) : 177.785 MB/s
Sequential Write (Q= 32,T= 1) : 754.454 MB/s
Random Read 4KiB (Q= 32,T= 1) : 363.910 MB/s [ 88845.2 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 323.220 MB/s [ 78911.1 IOPS]
Sequential Read (T= 1) : 1072.380 MB/s
Sequential Write (T= 1) : 925.886 MB/s
Random Read 4KiB (Q= 1,T= 1) : 110.147 MB/s [ 26891.4 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 104.604 MB/s

Here is the Cache Drive SSD as 2 x 512Gb Raid 0:
Sequential Read (Q= 32,T= 1) : 1470.751 MB/s
Sequential Write (Q= 32,T= 1) : 896.176 MB/s
Random Read 4KiB (Q= 32,T= 1) : 286.814 MB/s
Random Write 4KiB (Q= 32,T= 1) : 219.255 MB/s
Sequential Read (T= 1) : 1333.875 MB/s
Sequential Write (T= 1) : 839.268 MB/s
Random Read 4KiB (Q= 1,T= 1) : 107.761 MB/s
Random Write 4KiB (Q= 1,T= 1) : 88.941 MB/s

It appears that the Raid 0 of the SSD drives are faster. So, I'm still at a loss. What part of the system needs updated to accomplish 12 streams?
