Aggregation only works for upload, download is not aggregated

[tokon2000]

Expected Behavior

Aggregation of 2x 1000 mbit down / 50 mbit up should give me at least 1600 mbit down / 90 mbit up

Current Behavior

Speedtest shows me about 800 mbit down and 90 mbit up. When I test each interface, I get about 900 mbit, but only 800 mbit aggregated. What's wrong?

root@OpenMPTCProuter:/bin# ethtool eth0 | grep Speed
    Speed: 1000Mb/s
root@OpenMPTCProuter:/bin# ethtool eth1 | grep Speed
    Speed: 1000Mb/s
root@OpenMPTCProuter:/bin# ethtool eth2 | grep Speed
    Speed: 2500Mb/s

What is the speed limit on the VPS ? Did you try with omr-test-speed on the VPS ? There is also omr-test-speed-server vps eth0 that can test speed between eth0 and VPS. What tis the latency you have between each connection and the VPS (should be visible in status page) ?

OMG, found the problem. I forgot a part of my network that is only connected at 1Gbit. Now I have 1800 mbit down / 95 mbit up.
