Hi,
I would suggest to update to the latest version of the code, FreeBSD 9 Beta2. In addition to that, you might want to * enable NR-SACK: sysctl -w net.inet.sctp.nr_sack_on_off=1 * enable send/recv buffer splitting: sysctl -w net.inet.sctp.buffer_splitting=3 This should improve things. I've tested stuff with wired interfaces. Not sure how wireless interference might impact that stuff.
