Question

Slow speed when exporting in Adobe Premiere to NAS (by Samba)

Hello everybody,

I'm racking my brains to understand a performance problem.

I have a computer with these settings:
- 256GB NVME SSD
- AMD Ryzen 3700X CPU
- RTX 4060TI GPU
- 1Gb Network
- Windows 10 22h2
- Adobe Premiere Pro 2023 Version 23.4.0

And I also have a Raspberry Pi 4 NAS with Open Media Vault 6, with SATA 3 SSD (USB 3.0) and 1Gb Network.

Whenever I export a video with DESTINATION on the NAS SSD, the CPU usage is 35% and GPU 40%, with a speed of 100Mbps and reading and writing (12MBps).

 

When I export a video using my PC's SSD, CPU usage is at 62% and GPU at 50%, exporting 2x faster than when saved on the NAS.

When I change the source files, nothing changes, only when I change the destination.

I've already done several read and write tests, on my NAS I have 110MBps of write and read continuously (limited to 1000Mbps on the network card).

I also tested with a notebook at 1Gbps, sharing the folder and using it as DESTINATION, I have the same loss of performance and delay in exporting.

Does anyone know what could cause this export delay when using a shared folder on the network?

    There are obviously many variables here, but, I think I know what could be part of the reason. Put short I am thinking that probably your NAS is not able to keep up with the simultaneous read and write that happens when you export to the same device where the source media is. Depending on how complex your sequence is, Premiere Pro will be reading many files at once while it is rendering and then it is also trying to write to that same device. That's a very different thing than when you do a speed test, where a single file is written or read at full speed.

     

    Can you monitor the Raspberry Pi CPU usage during your exports? If the CPU and/or RAM usage of the Pi is very high then that is your culprit – it takes CPU power to handle more network loads and the Pi is the limiting factor. 

     

    In the case of exporting to your computer's SSD the flow of data is in one direction NAS -> your CPU -> your SSD so there the NAS is doing less because it doesn't have to also handle the writing of the export.

    @mattchristensen thanks for answering, think about it too, I ran the export and saw that the CPU usage is below 30%:

     

    Interestingly, when testing with an Notebook I5 (9400H) with NVME SSD sharing a folder, I had the same performance as my Raspberry Pi 4 NAS. It's as if Adobe Premiere doesn't handle shared folders very well on Windows. I tried to test using FTP Upload, but I can't configure the FTP port to 21, it only remains 0, even though I try to enter the value:
