Look at the load average, and my screenshots..
Can you describe what Load Average measures?
What are the limits, and what does it mean if you are exceeding them?
The load average is a ratio of free clock cycles to clock cycles that are performing a function for the router. If you have the CPU just clocking away not doing any major processing your CPU load average will be low....but if your processor is trying to do too much, some processes have to take a back seat to higher priority processes...this is where you can actually see the load average over 1.00 (100% utilitzed clock cycles)...the processes in waiting will show above the 1.00 limit.
There are 3 load average numbers...the first on the left is the load average over the previous one minute....then middle number is the load average over the previous 5 minutes, and the last number on the right is the load average over the previous 15 minutes.
hope it helps.
redhawk _________________ I currently test dd-wrt on Asus, Buffalo, Linksys, and Netgear. Too many to list.
Looking for more test units (newer models) for the project...got a brick?...PM me to make a donation. (USA) A donation is not a debricking service....it is a way to "Give back" to the dd-wrt project.
I do NOT provide personal assistance through chat or phone....so please don't ask.
I can add to redhawks description that 1.15 is the limit where a process has to wait for being serviced so the range is 0 - 1.15.
Multiply that value with the number of cpu cores to get the critical value, ie 5 cores then 5.75 is where processes has to wait for service.
I think the 4716-4718 cpu's has more cores than previous mips cpu's so it may well be that the load average doesn't show correct values for WRT320N and RT-N16.
It is therefore that I rather trust the top commands output for individual processes and the total for user,system, irq, sirq, and nic than believing in the load average figures.
I just replaced my Linksys WRT54G WDS-bridge with an RT16N. A 2nd RT16N is on its way which will replace the WAN-router. The first thing I noticed was the slow wireless link I'm having with my WL-500G Premium.
After bringing power down from 71 mW to 20 mW its speed went up to the full 54 Mbps...
Some programs don't run properly. fdisk -l without a devicename doesn't give you all the partition which is normal behaviour. swapon -s doesn't work either.
71 mW - 1 ~5.5 Mbps
20 mW - 54 Mbps

Another Asus RT16N as WDS-bridge
So please report dd-wrt running 13297 on this router only in this thread. _________________ SIG:

1. when i run multicast (iptv or radio) on LAN, internet on wifi die (CPU load 9%), after 2 minits wifi conection die (LED lights but can not connect). when stop multicast wifi come to life.
during run multicast can not connect to wifi.
i try on 13297 big and 13309 mini
2. wifi speed:
i test speed to internet. LAN 64/64Mbit downoload/upload
WIFI only 15Mbit
in router set mixed mod speed. current rate 54Mbit, TX power 17mW
in official asus firmware i have 20Mbit on wifi
1. Enable USB support and JFFS2 in Web GUI
2. Make sure the printer is loaded by runnig "dmesg | grep printer" (without the quotes) in Telnet
3. Run "ipkg update" (without quotes) in Telnet. If it gives some error go and disable, enable and clean JFFS2 a few times until it works.
4. Install printer server by running "ipkg install p910nd" (without quotes) in Telnet.
5. Run the following commands in Telnet one by one:
echo "/jffs/usr/sbin/p910nd -b -f /dev/usb/lp0 0" > usb.startup
chmod +x usb.startup
6. Now reboot the router by typing "reboot" (without quotes) and it should load the p910nd print server when it boots up. To verify the print server is loaded run:
