Block Diagram - Enquiries - 02-24-2025
Your recent video on network bottlenecks was brilliantly timed for me. I have a Ugreen DXP4800 Plus and a Trendnet 10 Gbps desktop adapter, and I am struggling to get more than 4 Gbps upload to the NAS and 2 Gbps down even though both have NVME Gen 4 drives, your insight went beyond what I could find on the internet. Plan to test a few things tomorrow based on your video. Network speeds are a common issue now as 2.5, 5, 10 Gbe are becoming mainstream.
I can’t find a block diagram for my PC or the NAS, and from the video it looks like you know how to “reverse engineer” it through Terminal, SSH, and Putty. It would be wonderful if you made an instructional video on this. I can’t find anything on the internet to guide me through it. I suspect my PC might be the cause, it’s an old Dell workstation that I am pushing hard in several ways.
Just wanted to share a video idea for your consideration. Or if you can point me to a resource to help me learn how to build a block diagram.

Thank you for the kind words! I’m glad the video on network bottlenecks was helpful for you. It sounds like you’ve got a solid setup with your Ugreen DXP4800 Plus and Trendnet 10 Gbps desktop adapter, but I understand the frustration of not hitting the speeds you're expecting, especially with NVMe Gen 4 drives in place. Hopefully, the tests you plan to run tomorrow will help pinpoint the issue.
Regarding your request for a block diagram, I completely agree that having a visual representation of your system can be incredibly helpful, especially when troubleshooting performance bottlenecks. Unfortunately, there's no easy guide I know of that covers exactly what you’re asking for, but I'd be happy to point you in the right direction.
Here are a few suggestions to build a block diagram or visualize your setup:
Reverse Engineering Through Terminal/SSH/Putty:
You can use commands like lshw (for Linux) or systeminfo (on Windows) to gather detailed hardware info, and from there, manually build a block diagram of your PC and NAS.
For your NAS, Synology and QNAP offer detailed system logs that you can access through SSH to see how your drives, network interfaces, and other components are being utilized.
Diagramming Tools:
Draw.io is a great free tool to create network diagrams and system block diagrams from scratch.
Lucidchart and Microsoft Visio are other alternatives that can help you map out your system.
Instructional Video Idea: I think your suggestion for an instructional video is a great one! I’ll keep it in mind for future content as this is something that can be very useful for people running into similar performance issues. I will also try to cover system diagnostics for PC and NAS using SSH commands.
PC Troubleshooting: Since you mentioned the PC might be the cause of the bottleneck, consider checking:
CPU and RAM utilization during file transfers. Older workstations might be limited by their processing power or network card performance.
PCIe lanes: If you’re using a lot of devices in your PC, it's possible that your PCIe lanes are getting saturated, especially on older systems.
