Can someone explain to me why Im only able to send 10mbps (ok 13mbps whatever) over a direct local gigabit link using bwtest to an RB750GL??? Thats not gigabit speeds thats 10/100 speed.
Also I can only recieve at 50mbps. Heres a screenshot.
Keep in mind, my pc is connected directly to the unit and this is the results im getting, or lack thereof.
UDP on the other hand gets up around 368mbps recieve and the same with send.
Hi,
similar issue with rb2011 in tcp with the default configuration(with the 3 default rules, firewall).
thanks
You should not use the TCP test on a Routerboard. If you want to test TCP performance: use 2 PC’s with IPERF.
Are you kidding me?
No, he is right. Always use BTest through a RouterBoard, not to a RouterBoard.
Ok guys I think that just sounds crazy and I have never heard that before.
Doing a TCP test is very stressfull for the limited CPU of a routerboard.
A TCP test requires doing checksums and replying with ‘ack’ messages. This is very CPU intensive.
So you are actually testing the CPU instead of the connection 
UDP does not require checksumming, that’s why you get much higher speeds.
That’s why you should use a normal PC on bothe sides of the link and do the testing between them (using iperf for example).
I would agree with you totally, but in my case, Im only getting about 32% cpu usage during testing with tcp send/recieve
