Package: wondershaper
Version: 1.1a-4
Severity: normal
Splitting based on packet size reduces the need for manual port
specification for my purposes of improving SIP phone response.
Also as soon as contention happens with child classes with a cumulative rate
greater than their parent, the parent becomes the queue. I have solved that
problem.
I haven't tested with allot 1500 and 1600 as in the original script with my
other changes. allot 3000 worked well in my testing, and allot 1500
shouldn't make much difference.
Comments please.
Thanks,
Mike
