Hello, good morning. I'm writing to you regarding a situation I've been experiencing since I joined this community. I've seen and noticed how speed test results are significantly affected after updating to OpenWRT. For example, I have a TP-Link Archer C7 V1.1 (AC1750) whose speed tests are above 500 MB. After updating to any version of OpenWRT, the previous results are significantly degraded, dropping by more than 50%. I wanted to know if this is normal or if there's some problem. Thank you.
it is normal, stock fw uses hw acceleration the open source driver doesn't have access to.
you can try to enable it, assuming it's supported for your hw.
Hello, good morning, Frollic. Thanks for the reply. I hope you understand, but I'm new to this. I'm asking how to enable hardware acceleration and how to know if my device supports it. Thank you very much.
See "Flow offloading type" drop down box at Network > Firewall. Not sure if a reboot is needed after setting change. frollic says the hw acceleration is only available to the stock firmware though so you will probably see no difference in throughput.
You can get rid of at least one switch vlan tag and improve forwarding speed. Offload also helps, just like not runn(ng any interactive taskslike luci while testing.
