Hey folks.
I've recently got a Flint 2. Running firmware OpenWrt 21.02-SNAPSHOT r15812+1071-46b6ee7ffc and kernel 5.4.238 with the actual version at 4.5.8.
I'm using the Flint 2 as a router with 5Ghz WiFi and other devices connected through ethernet and 2 TP Link APs connected through ethernet for other wireless clients.
I was doing some testing regarding latency whilst downloading.
My internet is 900/115. I have a client on the 2.5Gbps port.
I downloaded some content from Usenet @ ~44MBps and noticed later on a high spike in latency on my thinkbroadband quality monitor.
Look around 10am. https://www.thinkbroadband.com/broadband/monitoring/quality/share/b6d8e2ee3f3ac629962b2c7aaf0bd5d60c62dd8b-02-06-2024
When I noticed I decided to stop and check my router settings, I've got client VPN disabled for now and my Hardware acceleration is on.
So I resumed the testing and you can see the same spike in latency.
Compare this to 4 days ago when I was using my TP Link as the router and downloading at my maximum line speed where the latency was much lower.
What gives with this? How can I reduce this latency?
I had a Virgin Media modem back in the day with some broadcom or intel chip and it reminded me of the latency that I just saw.
I decided to do a bufferbloat test alongside the Usenet downloading. Here's the result https://www.waveform.com/tools/bufferbloat?test-id=2544e57a-971a-4fbf-8e5e-fc062e809f67
