Hello,
I recently installed a new RB5009Upr at home to support a new gigabit symmetrical fiber plan. When I try to run a SpeedTest (tried many different) from a wired computer on a 1G port I’m getting slightly asymmetrical results with 930 down and 940 up. I have a ASUS router with a 2.5G wan port and it doesn’t have trouble giving 940/940 to the wired computer. Internal network test with iPerf3 also give me 940/940 between computers on my LAN.
Setup:
- Fiber ISP profile (over-)provisioned at approx 1080/1080, validated with the RB5009 internal Bandwidth Test on a public server.
- ONT has a 10/5/2.5/1G port, negociated at 2.5 on ether1 of the RB5009
- Using PPPoE with VLAN tagging to the ISP.
- ISP supports baby jumbo frames, MTU on the PPPoE connection is 1500
- FastTrack enabled and appears to work properly on all interfaces according to traffic stats.
- CPU usage under 10% when saturating the connection.
This does sound like somethink linked with traffic coming from a faster interface moving a slower interface, but I’m not finding any configuration that seems to help. Flow Control enabled on all ports doesn’t change anything. The only setting that gave a negative impact was disabling the CPU Flow Control on the Switch. Tested on both 7.6 and the 7.7rc1 release.
I’m wondering what else I should try.
Thanks!
