Thanks, that seems like a simpler solution. But, I am still getting consumptions far exceeding the bw caps. I also see netstat -k reporting utlization exceeding 100% at times. I checked my code as well, and I don't see any problems with the measurement To see what's happening, I ran a wget on a 1G file. When I set the bw cap to a certain number, it works fine. Say to 200Mbps, and I download the file, it's limited to 200Mbps, no problem. But, if I change it in the middle to say 300Mbps, no cap is being enforced after I execute the 'dladm modify-vnic' command. In my SpecWeb experiment, I am changing bandwidth every 10 secs. Is that too fast? How long does it take for the (new) cap to get enforced? This may or may not be related to a problem we saw with 'tc' on Linux. We found similar problem with capping in tc and figured out that we had to set the right MTU and burst size for 1Gbps networks. Pradeep
