ACC

Post by MucuCat »

I was wondering why is ACC active even tho the class that requires ACC is inactive.

I have a gaming class with min RTT and Normal class with max wan utilization. even tho only Normal class is active, the acc still kicks in and lowers my bandwidth. For exmple i have 25 000kbps and it lowers my connection to 16 000. this is great when i play games, because i need as low ping as possible, but through the day when i am downloading, i cant use my whole download speed, even tho only normal class is active.

is there a way so that ACC only turns on when the class with min RTT is active? Or that it only lowers the available download when Min RTT class is active.

ACC =/= minRTT. minRTT just make ACC more aggressive in cutting down bandwidth to maintain lower pings. Personally I find minRTT unnecessary since my ping never goes up thanks to ACC.

If bandwidth goes down to 16k, it should go up if you there's actually demand for bandwidth (ie. try downloading a big file and watch if that number goes up over a minute or two). Again, that'll only happen if the connection is being maxed out. If it doesn't go higher, it might mean your ISP is congested during those times and that's what you're getting from them.

Only other suggestion I can mention is to try disabling minRTT on everything and see if that makes a difference. Chances are if you test (ie. max out your connection with downloads, then do a speedtest.net on another device to see your ping time) you won't see much, if any, of an increase in ping times even with minRTT disable.

If bandwidth is still being cut and you're sure there's more available, you can always disable ACC itself.
QoS Tip: Don't complicate your QoS settings. Gargoyle evenly splits available bandwidth between active devices as needed. Just delete all your classification rules and leave only one normal service class and you're done. No more arguing over bandwidth.

Without downloading i get 10-20ms ping (it may spike to 30ms sometimes).

i started downloading and maxed my connection with ACC and the max connection limit did go up (thank you) and i got ping around 100ms.

than i turned off ACC while downloading and my ping was around 130ms.

than i set max download for that class to 8000kbps and my ping was around 150ms! i always though that if i limit the max download that it will lower my ping.

so after this results i will stay with ACC. thank you :geek:

My resting pings are in the 20s, but even if I saturate my connection with a ton of downloads/torrents, it never gets out of the 20s. So I'm kinda confused as to why your pings increase that much. To other members, is this normal on your connections?

From the sounds of it, ACC is working as designed. Yes, sometimes bandwidth is cut too low, but rest assured if there's consistent demand (ie. a download for over a minute) that number will increase automatically.

One other experiment you can try is to try switching your ping target in ACC settings. Two easy options are Google DNS (8.8.8.8) or OpenDNS (208.67.222.222). I'm not sure which has the closest servers to you. Then you can try saturating your connection and test your ping times to see if that made any difference. I only mention this because Google DNS ping target works way better than my default (ISP) ping target. If it shows no difference, then continue using your default ping target.

What sort of difference do you mean? How well it handles your ping drops or something?

ok i tryed open dns and it gave me a bit worse results. than i tryed google dns and my ping was from 70-130ms. so the min was better, but i think for online games its better if the ping is stable so i will stick with my providers dns which gives me from 100-120ms when saturated.

is there anything else that i could try? because it would be amazing to have ping bellow 30ms even when saturated.

and also i would like to apologize. my connection upload didnt go to 25000, because it seems my provider set the max to 20 000. i tested without qos and it always stopped at 20 000. i have called them and they are resolving the issue.

and something else if maybe its importaint. last month i had ping spikes from 10-90ms even without gargoyle and i had to call them like 50x so that they resolved the issue. now i get from 10-20 max 30ms ping.

another person reported similar problems in the end they got a new router and the problem went away

Yes that's what I meant; if it led to fewer ping time increases/spikes.

That's my concern here because my ping does not increase at all even when other devices are downloading torrents... which is very impressive considering those have a ton of connections slamming the router.

The only thing I can think of, is try turning off ACC and setting your download bandwidth manually to something less than what your ISP provides (if they say 20k, set 15k, etc). Then max out your connection (torrent or big download) on one device and test your pings with another device. If they still hike up, it means your router is having issues controlling traffic for QoS.

thank you Volaris.

will try tomorrow when i come home. if it turns out my router is garbage, is there a really cheap alternative?
