pppoe CPU usage and FIOS

    Ok, here's a question for you guys regarding the HyperWRT firmware.
    Currently, I'm using sveasoft's firmware; however, I'm experiencing a serious issue with it and am thinking of switching over to HyperWRT. I have the Verizon FIOS 15,000/2000 package.

    With the supplied DLink router, I am able to get the following speeds:
    Download: 15000 kbps
    Upload: 1800 kbps

    With the sveasoft alchemy (RC5a), I'm getting:
    Download: 5300 kbps
    Upload: 1800 kpbs

    I think the issue is due to the PPPOE daemon running on the sveasoft firmware. It seems to max out the CPU at around ~5000kbps. My understanding that sveasoft uses the Mad penguin pppoed. Now, can anyone tell me if the HyperWRT firmeware uses a different pppoe daemon, or if anyone has experience with this issue on HyperWRT?

    I need to find a firmware that can support higher than 5000+ kbps coming in on the WAN port w/o maxing out the router's CPU.

    That's one of the reasons I made HyperWRT, to keep the high speed performance of the original linksys firmware. (I was using Satori that time and suffered low speed performance as you do)

    I don't think they are PPPoE related, as I'm using DHCP here.

    I don't know for sure, but It's most likely because sveasoft firmware has heavier packages (newer busybox, ...) and more features. These eat more cpu power, and that will result in less speed performance.

    Jees. That's a pretty big performance penalty. Verizon will be making FIOS available around here in the first half of 2005. I'll be getting the 5/2Mbps service though. Hopefully I won't have too much trouble.

    Yeah, I'm pretty dissapointed with that huge of a performance penalty. Previously I was on a 1500/384 DSL line, so I never noticed the issues with the Sveasoft pppoe implementation.

    FYI, I ran 'top' while doing a speed test on sveasoft alchemy RC5a, and at about ~ 5 mbp/s the pppoe daemon hits 100% cpu usage. That's cutting it real close, even on the slowest FIOS service plan, or on some fast cable modems.

    I'm going to try the HyperWRT firmware this weekend, and I'll report my results here.

    Any services you can disable in order to see if you can free up resources? Like possibly shutting down QoS or something. I wonder if it is specifically related to PPPoE. Maybe if you have the D-Link handle PPPoE and set the WRT in DHCP mode so it doesn't have to handle the PPPoE stuff. Who knows.

    I'm currently running Satori with tinypeap so I'd assume that uses less system resources than alchemy.

    What is the version number of your router? That could make a difference as well.

    I have the v2.0 router with the 200mhz CPU. Elsewhere, someone else stated that they could not get much above 4 Mbit/sec on the Alchemy firmware with PPPoE on a v1.1 router (125mhz cpu).

    I've heard at least one 2nd hand report that FIOS works fine (tested up to 14.7 Mbit/s) with the default linksys firmware, which gives me hope that HyperWRT will work.

    I really had nothing else other than the default services running (ie. resetbuttond, NO logging, local dns, QoS was disabled, etc).

    Switched to HyperWRT 2.0b3 and now my speed test generate these results:

    WRT54G w/HyperWRT 2.0b3:
    Download: 14758 kbit/sec
    Upload: 1787 kbit/sec

    Looks good so far!

    only got alchemy running on my v1 router cause i need the wds-feature...

    my inet-connecting-WRT54G runs with hyperwrt

    avenger, is there any hope of implementing the WDS-Feature ??

    Linksys has already some hidden WDS/Bridge code, it's possible that they are going to add this in the future.

    This is great info !! ill be getting Verizon Fios soon (within the next 2-3 months) and i was hoping to keep my WDS connection with my hyperwRT 2.1b1 firmware on a WRT54G 2.2 . Ill be getting the 15/2 package.

    CHeers for the info

    I read your message and I am interested in talking to anyone who could help me. I have verizon fios and WRTg4G and I am unable to use it! I called
    and they did not help me. I have a firmware from December...do you think this is the problem?
