Hi!

There is one annoying thing with bwm-ng: it shows the wrong bandwidth
with its default 0.500s timeout (see:
http://people.debian.org/~naoliv/misc/bwm-ng.ogv)

When playing the video see that the default timeout is 0.500s. Note
that it keeps switching between 0 KB/s and ~1700 KB/s (this value is twice
the real bandwidth usage)
When increasing the timeout to 1s it displays the correct bandwidth.

Thank you!

Best regards,
Nelson

Hi,

this issue is probably related to the kernel interface driver. I noticed
this with some drivers which update the values only once in a second.
Therefore i don't see a chance to fix this in bwm-ng unless changing the
timeout to 1s
