Hi all,

I throttled the bandwidth on a Ubuntu box for a test. The script looks 
something like this (snippets):

        tc qdisc add dev eth0 handle ffff: ingress
        tc filter add dev eth0 parent ffff: protocol ip prio 50 u32 match ip 
src 172.xx.xx.0/24 \
            police rate 34Kbits burst 5000 mtu 5000 drop flowid :1
          tc qdisc add dev eth0 root tbf rate 34Kbits latency 25ms burst 5000

The target systems are all on 172.xx.xx.0 . There's a perl script that loads 
pages that get's throttled just fine. When I run JMeter with an equivalent 
script it does not get throttled. 

Has anyone tried this or experimented with this? If so, does JMeter/Java 
circumvent the normal TCP stack or something?

Oh and I am aware JMeter can throttle too but in my situation I can't use that 
function.

Cheers
Oliver
