We have been trying to work out why bandwidth on our target board cant seem to get above 1Mbps even on a local network.After exhausting the obvious issues with the design we reverted to the WCD boards and iperf.iperf performance of a WCD8 board under 2.4 Beta 9 is [ ID] Interval Transfer Bandwidth[ 0] 0.0-10.1 sec 1.08 MBytes 899 Kbits/secSame board, some test environment under 2.3 yields:[ ID] Interval Transfer Bandwidth[ 0] 0.0-10.0 sec 10.8 MBytes 9.10 Mbits/sec-----------------------A WCD4 board (ST) under 2.4 Beta 9 yields:[ ID] Interval Transfer Bandwidth[ 0] 0.0-10.0 sec 13.7 MBytes 11.5 Mbits/secPerhaps the introduction of the ASF functions in 2.4 for the Atmel mcu has degraded something?
