I've been using this tool for a long time, but recently, I've noticed some very strange output behavior and I'm wondering if anyone has seen this before and if so, understands what the root cause could be (NOTE: Look at the summary line):
user@tm1:~$ iperf -su -i10

It's very odd to me because this seems to only happen when I run iperf through a tunnel. If said tunnel is not in the way, along the same path, I get a normal summation of the error %.
Any ideas?
