I did some tests with my FTTH 2.5Gpbs/0.5Gbps internet connection using PPPoE + VLAN with OpenWRT snapshot.
Both using an external ONT and the mini ONT MA5671A I can not go beyond 750-800Mbit in download (full bandwidth in upload). With an Asus router or the ISP ONU I go to full bandwidth (950Mbps with 1Gb ethernet clients).
Are there any performance issues or hardware offloading problem on the PBI-R3 using PPPoE and VLANs?
Does anyone use PPoE with VLAN and have done speed tests at 1Gbps and beyond?
All works ok on local ethernet connection. I’m using “OpenWrt SNAPSHOT r22257” with 5.15.98 kernel.
Probably I have solved… at least with this kernel/OpenWrt release.
I made a couple of test using the external ONT that is limited to 1Gbps Eth:
enabled only “Packet Steering” on " Global network options"
enabled both “Software flow offloading”/“Hardware flow offloading” on “Routing/NAT Offloading”
both 1 and 2 configuration at the same time.
Each of the three above seems to solve at least with 1Gbps connection the R3 reach 1Gbps.
It seems that the 2 and 3 one may be the best to be choosen cause the first 1 alone produce some CPU load.
Next test I will do is with the SFP ONT MA5671A on the R3 SFP Cage …
[EDIT] I get full speed also with the MA5671A on the SF cage!!!
Now I will wait the 2.5Gbps SFP Ethernet modules and the OpenWRT patch to make it working to test full ISP speed.
