[Click] Click SMP performance

Thu Nov 20 11:08:39 EST 2003

Louati,

Can you send us a copy of udpgenerator.click?

What kind of Ethernet cards are you using? How many ethernet cards?
What kind of PCI -- 64 bit? 66 mHz? What kind of memory system?

Is your Pentium 4 uniprocessor the same SMP machine with 3 CPUs
disabled, or a different machine?

When you run udpgenerator.click on the uniprocessor, are you using
click compiled for uniprocessor or SMP? That is, did you compile with
--enable-multithread?

Why do you believe that you should be able to generate 600,000 UDP
packets per second?

Thanks,
Robert
