Hello,

I am also trying to generate as much packets as possible - on a 10G
link, and have the following questions :
 - Could you provide me your nst_udp_pkt_18.txf configuration file, as
the one I wrote seems very slow
 - How do you measure the sustained rate ? With Click or with another tool ?
 - Why not using Click to generate (for tests purpose), as Schule was
trying to do ?
 - Does anyone know if there is a Linux implementation of netmap ?

Any help will be greatly considered !

Thanks,
Fabrice
