When bandwidth usage for any connection is very high ( in my tests - 20MB/s or 160Mb/s ), iftop-0.16 stops reporting usage for that connection and becomes unresponsive - ^C doesn't work. More specifically - the connection in question represents NFS UDP traffic.

How many host pairs have you got on screen? What CPU does your machine have?

It's the case even if I filter to just one host. However, I figured out afterwards, that the problem only occurs when I use -P ( which I've always used before ). If I take -P out - no problem at all.
