Posted: Sun Jul 02, 2006 15:38 Post subject: High load on newer builds
Did anybody else noticed that all newest builds after 1-2 days start to have load about 2 or even more? I've noticed it on my WRT54GL v1.1. For me last good build is from 22/06. I tried after it builds from 26/06, 28/06 and 01/07 and they all have this bug.
On the other hand FW from 26/06 works OK on my WRT54G v3.

no firmware issue-->closed
i have no timescheduler with a cpu load multiplier inside
please check your condition. each cpu load has a reason. any high bandwith causes higher cpu loads _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s
OK I'll investigate it closer. But it's not from high bandwith - I've simple home ADSL line with 1024/256 plan, 1 PC (WWW, email) and 1 VoIP adapter (PAP2) so no way to do high bandwith.

it can be pure wireless bandwith within the network. i can be heavy filesharing traffic. many ports in general. _________________ "So you tried to use the computer and it started smoking? Sounds like a Mac to me.." - Louis Rossmann https://www.youtube.com/watch?v=eL_5YDRWqGE&t=60s

I've got a WRT54G v5. I was very excited to hear that the v5 could be flashed without a JTAG and installed DD-WRT as fast as I could.
One of the reasons was that the stock vxworks firmware pppoe didn't work with my ISP. So I installed the image linked to in the "PPPOE is now possible with micro builds" posting (27/6 build). Well, pppoe worked, but the router was unstable. After a while it hangs, telnet and web access don't work. The connection is established but nothing after that. Load average, as displayed on the web page, was high, around 2.
Downgraded to v23_sp1_micro and things work fine (no pppoe, of course), with load average down to 0.2 or so.

you might also try newer builds for the v5. its not unstable. just pppoe takes additional memory if used. if you leave it disabled it should be stable like the original release _________________ "So you tried to use the computer and it started smoking?

tell us what specifically is causing the high load
Wow, that top command is great. Is there a place I can go read up on what each specific process mean? Like for example "ksoftirqd_CPU0", or "wland", etc. Thanks.

wland just repairs broken links if needed. the irq0 process is a kernel interrupt process. high load on this is almost network related.
qos for example which is running just on lan->lan, but not on wan causes very high load. so the fastest way of using qos is always in routed mode from wan port to lan/wlan _________________ "So you tried to use the computer and it started smoking?
