[Click] high performance click router

[Giorgio Calarco]

hi,

recently I've been involved in performance
measurements with the click ruoter together with the
University of Catania in Italy.
If interested, you'll find more details in the Springer LNCS
volume referred to the next QoS-IP 2005 conference
(should be published in february), where we have
described several tests ("Comparative Analysis of SMP Click Scheduling 
Techniques")


Anyway, I can anticipate what we've done here in Bologna, I'd tell
you to buy ___at least___ this kind of hardware:

- a dual Intel Xeon 2.80 GHz CPU (with the HyperThreading technology 
disabled)
- an Intel E7501 chipset motherboard with a 533 MHz FSB and four distinct 
PCI-X slots
- Intel 82544EI Gigabit Ethernet controllers, better if all are plugged to 
64-bit/133 MHz PCI-X bus
- avoid to use motherboard integrated NICs, most of the times they are 
connected onto the standard PCI
bus instead of the PCI-X one -> poor performance.

We have reached these throughput values:

Click SMP support disabled: 737000 64-byte pps
Click SMP support enabled + adaptive increase scheduling :750 64-byte Kpps
Click SMP support enabled + static scheduling (2PCIX buses at 133MHz + 2PCIX 
buses at 100MHz): 1250 64-byte Kpps
Click SMP support enabled + static scheduling (all PCIX at 133MHz): you 
should reach 1350-1400 64-byte Kpps

thus, we cannot achieve gb throughput using 64-byte packets, but you can do 
that easily
when the packet's lenght grows a bit.

We didn't notice limitations due to the PCIX bus, thus if you can buy a
faster CPU you could reach higher values.

Hope this can help

ciao
giorgio
