800mhz CPU only 32mbps throughput
-
I have a P3 @ 733Mhz and I have about 40Mbit/s. I don't use traffic shaping it use more ressource.
My interfaces are : Intel 82557 Pro/100 Ethernet and D-link DFE 580 TX (thanks to ebay :)) -
I can get around 90 mbit/s with a 1GHz C3 Nehemia CPU with ViaRhine nics in default config benched with netio WAN to LAN. I would say that both of your machines should be able to push more bandwidth than what you actually see. However, depending on the traffic you probably see less. Make sure that you are not using shared interrupts (you can find out by going to http://<pfsense-ip>/status.php; check dmesg at the very bottom of this page). Another option that you could try is enabling polling mode at system>advanced to soo if this helps a bit (IIRC the CPU-Usage at the statuspage won't be calculated correctly if polling is enabled but this is only cosmetic).</pfsense-ip>

This is my DMESG. How can I control shared interrupts ?

2 of your nics share the same interrupt:
... ste2: <d-link 10="" dl10050="" 100basetx=""> port 0x1400-0x147f irq 18 at device 6.0 on pci3 ... fxp0: <intel 100="" 82557="" pro="" ethernet=""> port 0x2000-0x201f mem 0x40400000-0x40400fff,0x40000000-0x400fffff irq 18 at device 10.0 on pci2 ...</intel></d-link>Try to disable as much hardware in the bios as possible to free up ressources (like parallelports, serial poerts, …). Maybe you can get rid of the interruptsharing.
-
actually how do i go about testing the max throughput for my setup?
-
Try a tool like netio: http://freshmeat.net/projects/netio/
-
thanks! will try it out
-
Also, try Intel nics. 3Com nics are generally regarded as bottom of the bargain barrel cards.

I do some tests :
Wan=> Lan : At 13Mb/s (this is my internet connection throughput) :
Snort uses 33% of CPU and processor utilization about : 50-60% (total, snort include)And LAN=>OPT1 I estimate maximal throughput at 40Mb/s without snort.
I have some share IRQ, I tried to disable serial port, audio, usb …. and I still have share IRQ ....how can I resolve it ?
thx for your help ;) -
Reset the asigned ressources in the bios or try to manually assign them. Also swapping pci slots might help.
