[TL-ER6120] The UDP throughput from LAN host that obtains from PPPoE Server to LAN host that obtains from PPPoE Server is very low.

I configured the TL-ER6120 as follows.


1. In LAN WEB UI menu, I enabled DHCP Server with start IP 10.100.10.100 and end IP 10.100.10.199.

2. In PPPoE WEB UI menu, I enabled PPPoE Server with IP Address Pool 192.168.200.100-192.168.200.199.

3. I connected my notebook1 with TL-ER6120 LAN Port 1 and my notebook1 got IP addess 10.100.10.109 from DHCP Server.

4. I connected my notebook2 with TL-ER6120 LAN Port 2 and my notebook2 got IP addess 192.168.200.100 from PPPoE Server.


5. I tried the throughput test from notebook2 (jperf client) to notebook1 (jperf server) with jperf tool ( https://code.google.com/p/xjperf/).

6. The TCP throughput was about 190Mbps but the UDP throughput was under 20Mbps.

For incresing the UDP throughput what I do or configure more ?

I attached the jperf result that I caputed on my laptop screen.




Thanks in advance.
