limiting DL speed on very high speed network problem

[albancachot]

Hi,

I need to limit the DL speed on a very high speed network (10 Gb/s) to 2,2 Gb/s

I notice that there is no link between DL limit in kb/s and effective DL speed (mesured with iftop)

/usr/local/sbin/wondershaper -a eth0 -d 2200000 --> speed mesured with iftop is barely 1Gb/s per second

/usr/local/sbin/wondershaper -a eth0 -d 3900000 --> speed mesured with iftop is 2.2Gb/s per second BUT the next day barely 1.9Gb/s

so I cleared the conf and set another value

/usr/local/sbin/wondershaper -a eth0 -c
/usr/local/sbin/wondershaper -a eth0 -d 4500000 --> speed mesured with iftopis still stucked around 2Gb/s

Note : each time I clear the configuration, the speed increase to 5 or 6Gb/s; so there's no network issue in this case I think

Has someone already encounter this issue ?

Thanks
