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/sec

Same 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/sec

Perhaps the introduction of the ASF functions in 2.4 for the Atmel mcu has degraded something?
