Huge packet loss on C2600

Hi,

I noticed when torrenting that I get huge packet losses while using the Internet. I "pinged" from my laptop and from router level (SSH) and there are over 25% of packet loss to the nearby servers. I have SQM active but to be honest I still struggle with bufferbloat. This didn't happen on my old WR1043NDv1 even though it couldn't handle my connection.

PS. I can't even do a speedtest due to timeout error and my current connection speed is something around 20Mb/s from 250/20 available.

Do any of you experience something similar?

I had pretty identical set-up on WR1043NDv1 and then for short time V4.
With C2600 there are issues. The bufferbloat on 2.4 Ghz is through the roof and with heavy torrenting the bufferbloat in general is not very well which didn't really happen on previous routers.

Run top and see what sirq looks like when testing...

I run htop.
Both cores were around 50%. One of them sometimes hit close to 100% but not all the time.

What processes are running high?

What's the dmesg output look like?

During heavy torrenting I got something around 20 Mb/s on my BitTorrent client with another 20 Mb/s during speedtest on WiFi from another laptop. The CPU idle on C2600 was round 60% with 30% of sirq. There is plenty of raw power, yet the packet loss is significant. Sometimes I can't even open a website. I have to wait a while. I've never had this problem on my previous routers, not matter how much load was put on them, the websites always opened properly.

This is a speedtest made during the torrent activity. It's basically shit.

I see allot of disk errors in your syslog, you either have a bad disk or you use a chipset that's not well supported in Linux. Where is your torrent client located? On your LEDE device or on your laptop?

I assume that you use below disk as rootfs for your LEDE device?

It could be that because of this bad disk the CPU is handling allot of IRQ's and therefor has less time to forward/router packets. And that's why you see that packet loss.

The BitTorrent client is set-up on an old netbook that also performs a role of local storage server.
The disk you've mentioned is an old MP3 player connected to the router as a storage device for sysconfig backup and logs. It's not a rootfs device. It's just for storage. I'm also aware of the bad disk errors in syslog but I don't worry about it since it's not a critical part of my set-up and the router can perform without this device connected anyway.

I've seen something somewhere about number "of switcher or packets on internet switch" that might cause this issue. Before I had an Realtek based switch so this might be somehow connected.

I've also seen this so I think those two problems are somehow connected:

Yeah true, I would agree on that if you did not have any kind of problem. But since you're here because there is something wrong it would be best to remove all possible fault situations, including a faulty USB stick. Agree?

For example it could be that your MP3 player has a bad battery and therefor uses to much power from the systems 5vbus which will influence the hardware. This is just one example.

There is no battery in this MP3 and I've had it connected to different routers for years now without any problem. Also the power supply for this router is quite capable.

I feared that you might say that. But ok, then I'm out. Sorry

In my opinion I think its best to start clean. And slowly build your way to the fault. Otherwise it's looking for a needle in a haystack

I understand your point.
I will try to disconnect this MP3 player for some time and look for a difference in performance. It can't hurt, right? At least we will be sure it's a cause (or not). I also have printer connected to this router. Do you want me to disconnect it too?

To be fair... the printed is turn-off most of the time anyway.

Great, that you've made this decision! Yeah I noticed the printer, please remove any auxiliary devices. Did you install anything on your C2600?
Maybe it's best to disable them as much as possible.

I did but again it's the same list of additional packages that I used for years. Some of them are essential to my set-up, including SQM. If I remove it how will I know if it's working properly?

I will try to disable the non-essential.

You know when it's working if you don't experience any packet loss. If it's fine add stuff until it breaks.

You may also completely ignore my advise. I don't mind, that's up to you. I just want to create a path to pinpoint this issue. I have no idea where the problem relies either. But with this method we make sure that it is not caused by any auxiliary devices or software.

Just like when you bring a car to a garage and say I've put gasoline in it for years and now it suddenly stopped. The mechanic will also start with the essentials. He/she can't just walk to the workbanch and get the magic light bulb to fix the issue.

Ps. Maybe it's an option to put your old router back and test this device in a more workbanch like environment? So your main network is not effected when you test new stuff?
