100% CPU

[proverbian]

Hi, i have this specs

Intel(R) Celeron(R) CPU 2.00GHz
2GIG RAM
80GIG HD PATA
4NIC - DLINK

Captive Portal Enabled.
3 WAN 1 LAN

and it reaches 100% CPU, always 40-70% and sometimes 100%

system –> advanced --> networking is OFF.

top -S -H give me this ..

PID USERNAME  PRI NICE  SIZE    RES STATE    TIME  WCPU COMMAND
  11 root      171 ki31    0K    8K RUN    85.7H 40.77% idle
  12 root      -68    -    0K  152K WAIT  484:11 11.38% {irq17: vr1}
  12 root      -28    -    0K  152K WAIT  189:06  5.18% {swi5: +}
  12 root      -68    -    0K  152K WAIT  173:34  4.20% {irq19: xl0 uhci1}

How much traffic are you passing at that time?
using top -SH is a better measure in my opinion. If you open an ssh session and run top -SH and then open the webGUI to view the dashboard you'll see the CPU usage go up considerably. I.e. simply viewing the dashboard on a system of that type uses CPU cycles. On my own low end P4 it uses quite a lot!

Which options in System: Advanced: Networking:?
