The LS1012ARDB TX network is very slow

[jasonwu0527]

   I used iperf testing network throughput, client is LS1012ARDB and server is Ubuntu 16.04, the test results are 23 Mbits, following is iperf logs:
[ 3] 0.0-300.0 sec 824 MBytes 23.0 Mbits/sec

   I exchange iperf server and client, server is Ubuntu and client is LS1012ARDB, re-test, following is iperf logs:
[ 5] 0.0-300.0 sec 29.6 GBytes 848 Mbits/sec

   In addition I tested HTTP file transfer, the LS1012ARDB is HTTP server, download the HTTP file with the google chrome, about speed 4-11 Kbytes,

Ubuntu firefox  HTTP download speed is Unstable, most of them are 5xx ~ 9xx Kbytes, sometimes 2x Mbytes,

Why is the LS1012ARDB TX network speed so slow? Please help me.

I have uploaded a detailed log file.

Hello Jason Wu,

The iperf test data is abnormal when LS1012ARDB is used as the client.

Please refer to the following test data we got in EAR 0.5 test.

Did you perform iperf client and server test on LS1012ARDB under the same boot Linux system without reboot?

Because I didn't find eth1 pfe open information when doing iperf client test.

IPERF/IPERF3
		Command	The size for buffer (-l)	Bandwidth(Mbits/sec)
With PFE  （NotSet optimization parameters）	UDP	iperf -c 10.193.21.79 -u -b 1G	NA	803
		iperf3 -c 10.193.21.79 -u -b 1G	NA	996
	TCP	iperf -c 10.193.21.79 -t 100 -P 20	NA	934
		iperf3 -c 10.193.21.79 -t 100 -P 20	NA	940

Have a great day,
TIC

Hi Yiping,

   Thank you for your reply, but I can no't find the EAR 0.5 version download link on the "QorIQ Linux SDK v2.0 Download" site,

    Where to download the EAR 0.5 version?

     Thank you.

Hi Jason, 

do you have any ipdate on this topic? We are testing the same issue.

Thank you for your help.

I re-tested according to your iperf parameters.
Ubuntu and Windows 10 are different computers.
The speed of the network is not good.
Please help me.

I can not find the  LS1012ARDB 0.5 version download URL, so use 2.0-1703 versions of the test.
