slow editing experience when editing from fully kitted out network infrastructure

Your media is mostly long-GOP mp4, and your CPUs are all Ryzen/AMD ... um, that's an issue right there.

As someone with a darn good 24-core Ryzen myself ... that total lack of long-GOP hardware is a pain in the tush. "We" don't have Intel's QuickSync, and AMD hasn't yet given us a replacement on their CPUs.

So that may be part of your problem. To test, make ProRes 422 or Lt transcodes of the media on a sequence. Create a sequence with that media, and check playback.

Hello @10966675,

I read your notes. You are having performance issues with your media files located on a remote server even though the bandwidth seems to be available. Is that right? Edit: I watched your video and that seems to verify that is what you are having problems with.

• Is Premiere Pro installed locally?
• Do the client computers exceed basic system requirements?
• You say your project files are large. 
  • Have you considered breaking down large project files into a "Production?" 
• You say that your media is stored on the server, not locally. 
  • What kind of media is it? 
  • Your movie indicates that you are editing with 4K and 2K files. Are they using the H.264/HEVC codec? If so, this media is non-performant and not ideal to edit with remotely.
  • Consider proxies or transcoding, and then move these files locally for editing.
  • It's fine to store media on the server, however, one should avoid editing non-performant files directly from the server:
    • Download them to the local computer, then edit with them.
    • Why is it necessary to edit these non-performant files from a server?
• Are your media cache files living locally? They should be.
• Premiere Pro has no special features designed to tune the application for use on networks. 
  • Premiere Pro was designed to run locally. 
  • If you must run the project file over a network, you must take certain precautions. 
  • Most people use their IT admins in congress with special video VARs that have installed, tested, and support the system. 
  • It is not trivial to run non-linear editing applications over a network, especially with:
    • Non-performant media like H.264 and HEVC
    • 4K frames
    • High frame rates
    • Variable frame rates
    • Video files with a long duration
    • Sequences with long duration, etc.
  • If your scenario has any of these things, you should definitely take action.
• Resources: See this FAQ from Bob Zelin discussing the network setup for NLEs running on QNAP hardware: https://www.bobzelin.com/qnap-frequently-asked-questions
  • Note the section where Ethernet connectivity with the computers on the network is discussed: "For 4K media editing, I strongly recommend using thunderbolt to 10G Ethernet adaptors on the editing computers, or 10Gb Ethernet PCIe cards if you have Windows PC's or old Mac Pro's. These products are made by Sonnet Technology, QNAP, OWC, and ATTO Technology."
    
    

I hope the notes help. Note that Adobe Support cannot really assist you with running Premiere Pro over a network. 

I used to be in IT at Deluxe Digital Studios running XSAN with 24 or so clients. For performance issues I couldn't fix, I needed to consult the VAR that installed the network, as well as Apple, who are hardware manufacturers, so they supported this with a specialist from Apple. If you cannot solve this, I suggest you reach out for help from your IT department or from a VAR. 

Come back with any questions, and I hope I can help steer you in the right direction.

Best of luck to you,

Kevin
