I have two t4240rdb boards using kernel, dtb, filesystem taken from sdk 1.6. </P><P>I use ixia&nbsp; to&nbsp; generate packets. While I am sending packets at a rate of % 100 only in one direction the performance is 400mbps.But while I inject packets at a rate of % 100 in both direction i got 300mbps as an aggregate performance. Why the aggregate performance is not around 2×400 mbps on such a high performance board. I couldnt even reach 400mbps.</P><P>After conducting some tests I reached&nbsp; an&nbsp; interesting result. If I decrease the traffic rate near % 60 I got an aggregate 2×420 mbps performance. And&nbsp;&nbsp; I&nbsp; observed the performance is starting to decrease if the packet drops started. I couldn't explain why the performance is dramatically decreasing if I exceed a traffic rate % 60. As if there is a rate control mechanism which limits the total packet throughput. Any help will be appreciated. </P><P>Best regards</P></BODY></HTML> Fri, 15 Jan 2016 19:05:16 GMT https://community.nxp.com/t5/T-Series/T4240rdb-network-performance-issue/m-p/493374#M773 sedat_altun 2016-01-15T19:05:16Z Re: T4240rdb network performance issue https://community.nxp.com/t5/T-Series/T4240rdb-network-performance-issue/m-p/493375#M774 <HTML><HEAD></HEAD><BODY><P>There must be something not configured properly.
