Hi,

I have faced the exact same problem with DelayUnqueue that Adam has
mentioned.Basically I am trying to evaluate NISTnet v/s Click for
emulating delay in my project.
(nistnet is available at http://snad.ncsl.nist.gov/itg/nistnet/)

I have an Intel Pro 100OT gigabit ethernet card and running redhat 7.3. I
am generating packets using RUDE (http://rude.sourceforge.net/). Once I
reach a rate of about 8000 packets per second (small 64byte packets), the
Queue starts to build up and eventually packets are dropped. I have the
timestamp element in place as you mentioned.

Ryan
