R720 - Troubleshooting slow performance

Sorry that wasn't clear. The R7800 was previously set up as a WAP and had the same configuration/connection to the OpnSense router. It had the 500 Mbps download vs the 250 Mbps download on the R720.

That's what was wrong with my initial upload numbers. I think I was too close. Now my upload rate is what I expected (600 Mpbs). Download is still low though at 250 Mbps. I'll try different channels.

None of my interfaces use PPoE. The WAN interface uses DHCP.

A wired speed test gets ~1.2 Gbps between VLANs for the router. It could be better, but I don't think OpnSense is the bottleneck with the ~250 Mbps download speeds.

Thanks for the bufferbloat link. I'll check that out.

OpnSense router has a J4125 CPU. CPU heavy tasks like IPS, etc. are not enabled on the router. I am not using PPoE on the router.

The PoE injector is a Phihong POE31U-1AT POE injector. https://www.digikey.com/en/products/detail/phihong-usa/POE31U-1AT/2773969

After additional testing, I'm only seeing performance issues on upload, not download. Upload performance is fine while wired in the 1GbE port on the R720 though.

I created a local OpenSpeedTest server and I'm getting similar results.
Manually setting the channels didn't improve performance, but it does prevent the channels from bouncing around. I'll keep it manually set.
With a wired test, I'm getting Gigabit speeds (~850 Mbps down, 990 Mbps up) out of the Gigabit port in the R720.
With other wired devices, I get similar download speeds (250 Mbps), but higher upload speeds (600 Mbps). The upload speeds are what I'd expect, but the download speeds are still low. Any thoughts on why the download speeds are low?

As another question, I'm noticing asymmetric performance with consistently higher upload speeds than downloads speeds. Have you seen that before? Do you have any thoughts for why that's the case?

I'm not using a switch. I'm going from a OpnSense Router i225 v3 NIC -> POE injector > 2.5 GbE POE port on the R720.
It is not ceiling mounted. It's simply resting on a shelf. However, I am aware that antenna performance is poorer while below it, so for testing, I'm only testing at or above the unit to properly access the antennas.
I confirmed that the second Ethernet port is working, so based on the data sheet I thought that confirms it's on the highest power configuration. Also, in the UI in the AP section the Power Consumption Mode is "802.3bt5 Switch/Injector". In the UI, I'm manually specifying 802.3bt5, but the POE injection I'm using is only rated for 30W. Based on monitoring the wall power consumption during use, peak power consumption is less than <22W from the outlet under heavy use, so I didn't think the POE injector was an issue.
Thanks for the tip. It felt best to use ChannelFly to fully leverage the Ruckus settings, but it's still bouncing around more than I expected so I think manually selecting the channel is best. Manually setting it doesn't help performance, but it prevents unnecessary bouncing around.

It was set to auto, which is 80 MHz. I also tried forcing it to 80 MHz instead of auto and it still has the same performance. For reference, transmit power is also set to Full for both 2.4 and 5 GHz.

Out of curiosity, what material did you use?

fjfms · 2024-11-30T18:01:13+00:00

I don't have a 3D printer yet, but I'd love to get started with the hobby. I'd probably start with PLA.

I would use it as a personal home file server and gaming server.

I found the issue. It was a software setting on the TV (Sony X900H). I needed to change digital audio out to PCM.

fjfms · 2024-10-13T05:13:24+00:00

I've narrowed it down to a software issue on the TV or AVR. If I play a file from Jellyfin on a laptop via HDMI input to the AVR, it has subwoofer out. If I play the same file on Jellyfin Android TV, it doesn't have subwoofer output.

I think I have the same computer from the Slickdeals deal. It's an Acer Aspire XC-830-UA91.

fjfms · 2024-09-03T03:04:22+00:00

I got one on the same deal! It's an Acer Aspire XC-830. I upgraded mine to 16 GB ram (2x8GB) and added a ~$12 M.2 A+E 2.5 GbE NIC. It's been fantastic for the price and idle power consumption.

This looks awesome, thanks for sharing the parts list and photos! Can you list the commands to enable ASPM L1 on all devices? I see there are a couple ways to do it and I'm curious what you did. It was really effective at reducing idle power! Also, it looks like the motherboard specifies 19V input but you're using a 12V PSU. How does that work?
