The buffer size we are using is 128KB with one channel and one thread, the throughput is about 382209 KB/s. The test we are using is dmatest available in Linux kernel. If we increase the number or channels and/or threads. the performance go down dramatically.</P></BODY></HTML> Thu, 14 Apr 2016 17:44:29 GMT irfanmalik 2016-04-14T17:44:29Z QDMA Performance https://community.nxp.com/t5/Layerscape/QDMA-Performance/m-p/505840#M1117 <HTML><HEAD></HEAD><BODY><P>We are experimenting the QDMA to get better throughput a on freescale reference board.
