I wonder how I can monitor which process takes out all my IO bandwith. The only command i know is gstat but it shows cumulative info. Is there any tools i can use to inspect the running processes for their io usage? The system is FreeBSD 8.3

Thank you

May be tool "iotop" can help you. – Vadim Dec 27 '12 at 22:27
@Vadim iotop doesn't exist on FreeBSD. FreeBSD is not Linux. – Chris S Dec 27 '12 at 22:50

You can use FreeBSD top to achieve this.

While running top interactively, press m.

According to top man page :

       m      Toggle the display between 'cpu' and 'io' modes.

Of course, this tip won't work under linux as linux top and bsd top are different programs.
