Aha, so there we have it! That is exactly what I and some others have described, when having the self refreshing page with stats open you get high(er) loads.

I'm wondering, but does that effect last when you stop using DHT? Mainline DHT has the side-effect of sending DHT-UDP packets to you for almost a week after your last connection (at about one packet every two seconds). Eats up 10 to 20MB of bandwidth a day Sad

Hi,

what is bcrelay doing? It eats up around 25% of my CPU time. If the router reboots, it starts after a couple of minutes to grap CPU time again.

I am using DD-WRT v23 SP1 Final (06/27/06) vpn.

It does, just not as much, the packets are less frequent for me, then when the torrent is actually running.

Also, if and when it gets real bad, I just force a new IP address from my provider, then all gone :)

I've the same firmware but switched off remote mamagement and HTTPS on LAN. So this is default setup. So we'll see what will happen.

Hi, I have a problem with high load averages too.

hw: Linksys WRT54G v3.1
fw: DD-WRT v23 SP1 Final (05/16/06) vpn

I enabled the PPTP server, and worked fine, however after the PPTP client disconnecting, bcrelay started to eat up CPU resources. After several hours of running the load average was about 1.10. After a "kill -HUP bcrelay" the load went back to 0.02.

Simple info:

Code:
Firmware: DD-WRT v23 SP1 Final (07/02/06) vpn
Time: 23:29:40 up 3 days, 3:20, load average: 0.00, 0.00, 0.00


So it seems that HTTPS or WWW on WAN or both on WAn makes high load.

Update: the CPU load is caused by high Internet traffic, but it is unclear, how bcrelay fits into this. The traffic is unicast, so not related to broadcast packets (does bcrelay intercept *all* traffic on the br0 interface?).

I didn't want to open a new thread so I'll put it here. Why aren't the changelogs being updated every once in a while? v24 changelog is from 2005 :-/

Yes - I remeber. Now BS shoud read it and think about it.

But it's not a 100% HTTPS bug - as I mentioned I've also WRT54G v3 with the same firmware with HTTPS on WAN & LAN ad take a look:

Code:
Firmware: DD-WRT v23 SP1 Final (07/02/06) vpn
Time: 19:42:26 up 10 days, 6:27, load average: 0.00, 0.00, 0.00

you can get the changelog informations from the bug tracker too (look for resolved entries)

It eats CPU on my router too. I am using v23-SP1-voip. Everything works just fine after I kill this process. Who needs it anyway?
