I am trying to limit bandwidth on one of my KVM guest using Wondershaper.

Doing something like this works fine:

wondershaper br23 9000 9000

Doing a wget with the setting above gives a download speed of about 1MB/sec like it should.

However, it seems this is the highest setting I can use, because setting it to this does not work:

wondershaper br23 10000 10000

Doing the same wget with the setting above downloads with full speed, about 70MB/sec in my case.

Running a status-check returns the following:

What am I doing wrong? Does wondershaper have some kind of upper limit?
