I think we tried that, but I'll check again. And make sure your ftp client/server isn't resetting it to something small afterwards. For testing this, I'd use a real IP benchmarking program like iperf/netperf/ttcp, as they'll let you test different buffer sizes easily (and in the case of iperf tell you what you're actually using if you hit the limit) For a fast WAN you want something like 512k-1M buffers easily.
