[Click] Click SMP performance

[Giorgio Calarco]

I would add these questions:

- do you really have 4 CPU ? Or is it what the Linux kernel believes 
due to Xeon Hyperthreading ?

(PS nobody answered my question about Hyperthreading...5/11/2003)


- Is packet length = 64 byte ?

PS a curiosity: had anyone noticed this (http://news.gmane.org/gmane.network.routing.click) ?

  Subject: [Click] Click SMP performance 


  Hi all,

  I have installed click SMP on a multi-processor plateform (4 CPU Intel XEON(TM) Processor MP 1.50GHz).

  I try to generate 600 000 UDP packets per second with a click configuration (udpgenerator.click)

  So if i run :

  Click-install -t 4 udpgenerator.click

  The maximum throughput it can generate is 230 000 p/s ! ! !

  When i try to install the same click configuration on Pentium 4 Uniprocessor 1,5 GHZ ; it can generate 430 000 p/s (max).

  I think that i have some problemes with Click SMP performance !   

  Can you help me !

  Think you very much

  Wajdi
