Yes, I meant 10Mbytes/sec, since we have 1gbit interfaces. I have an
apache server serving a 1G file, and I download the file from another
machine, that is on the same enclosure. So, the network is very fast.
I see an output like below. I posted a message earlier
(http://lists.xensource.com/archives/html/xen-devel/2007-03/msg00026.htm
l) describing similar problems with tc as well. I have tried this setup
in a separate set of machines connected with 1gbit interfaces with same
results. Any help is greatly apperciated.
