Lags

Sebast1an · September 4, 2021

Heyo,

recently on ETL1 my ping has been 70-90 whereas normally it used to be 50-60. On top of this some maps just lag more than before - I've noticed it quite well on Erdenberg as that map lags a lot these days compared to before (lag as in spikes in lagometer, fps is usually fine). On my end nothing has changed in the last year so I guess this could be related to server setting changes somehow? I tried ETL2 and ETLC, with bots, and on both servers my ping was 48.

Only server change I can recall that could have an effect is /rate was forced to 35000 instead of 25000 some time ago. Not sure if it could have this kind of effect though. I've tried all sort of tweaks to my cfg without much success but I hope some of you may have some new suggestions to try. Cheers.

I'm rocking a whopping 24/1 Mbps connection which hasn't changed in a while. Let me know if you need to know some other specs. Also here's my config:

Added the cl_maxpackets value that was missing from the cfg for some reason

MiniMuppet · September 4, 2021

Other then the rate setting we haven't changed anything. Other then adding new builds. I can lower the rate setting next time you are on to see if it makes a difference but not sure it would.

Sebast1an · September 5, 2021

Thank you Mini, I think it's a good idea to try regardless just so we know it's not about that.

Just tested it on ETL1 with bots, thinking it might have something to do with the amount of people. But unfortunately that makes no difference.

Zyxpix · September 5, 2021

This is a routing problem I think and you should contact your ISP

ETLegacy main is in France

ETLegacy 2 is in Germany

A routing problem sounds very logical to me, thank you. I did tracert on both ETL1 and ETL2 and these were the results:

Could those "request timed out" messages on ETL1 be the cause of the problem?

So, yeah, it looks like your problems start when you hit Telia's network. This doesn't surprise me, I've had issues in my work with them and they are singularly unhelpful.

This might be a blip or a problem peering between Telia (backbone) and Hetzner (the host). Given that you get +20ms to both servers when you hit Telia too, I would say that Telia is having peering problems.

As an end user there's very little you can do, just let your ISP know that there seem to be issues with Telia.

MiniMuppet · September 6, 2021

to be honest they both look good and it just skips the ones it can't connect to. If there was a issue your pings would be a lot higher.

Sebast1an · September 7, 2021

Thank you all for your help. I'll contact my ISP (Telia) about the issue and we'll see if it ever gets better.

Ande · September 7, 2021

say that my telia lags too

Alistar · September 8, 2021

I have also high ping with telia provider. Got 1000 m connection still having 80-100 ping.

Some maps lag way worse than others from my experience and Erdenberg is absolutely the worst culprit. It's impossible for me to get a stable 200ms ping there. I have also noticed that the latency spikes are aggravated the more players there are. My theory has been that it's due to two things:

1. Bandwidth bottleneck somewhere in the network path. Bandwidth saturation produces knock-on effects like elevated or unstable latencies.
2. Map geometry is not well sectioned (or has leaks) so you end up with far more server traffic than necessary to update invisible players.

(2) is maybe testable by recording a demo and playing back using r_showNormals 1.

From the EU, network bottlenecks really shouldn't be a problem. To check this, you could maybe run Speedtest (https://www.speedtest.net/) from your computer and picking the ISP the main ETL1 server is on.

One misconception behind network issues is that the problem lies on one end or the other i.e. the ISP or the game server in this case. In reality, it very much depends on the routing between the two endpoints and the problematic node on the path could belong to an intermediary.

As far as client tweaks is concerned, there is the setting of packet duplication to off (cl_packetDup 0), reducing snaps, reducing rate and reducing cl_maxPackets. Except for cl_packetDup, the ETL1 server is unfortunately too restrictive for any of the above to work. I have always wondered if it would be better to set a range of acceptable snap and rate values rather than fixing it to 40 and 35000 respectively.

On a sidenote: regarding traceroutes (or tracert on Windows), you have to be careful with interpretation.

1. Most service providers will ask you to provide traces in both directions because the forward and reverse paths may not be the same.

2. It is alright for intermediate nodes to not respond to traces. Pings and Traceroutes use a different protocol (ICMP) and are considered 'control traffic' instead of 'data traffic' and switches/routers prioritize forwarding data. The right way to interpret Traceroute results is to look at the trace in reverse, beginning from the destination. Note down the latency and losses, then work backwards to the earlier nodes to observe the progression.

For me on non standard map like enderberg the problem was with com_hunkmegs and com_soundmegs, values were to low, when i adjusted them everything started to working perfect

Mister J · September 14, 2021

I increased all those megs too, problems persisted. I did notice that ET is using much more resources than it used to. Not that this should be a problem in 2021. My wooden computer however is actually starting to have issues running the game. :biggrin:

Which values do you use for hunkmegs, soundmegs and zonemegs?

lost · September 15, 2021

512 for hunk and sound, 64 for zone

StiffWrists · September 16, 2021

I'm basically right about something wrong with Erdenberg. Every area is 'visible' no matter where you are. In the screenshots attached, you can see that both radars are drawn despite how far and how obscured they are from the Allied first spawn. Data for practically every player in the map will be transmitted no matter where they are, generating a lot of unnecessary traffic.

Compare it with Supply Depot, where most of the hidden areas are dropped from processing.

Is there an updated version of this map that fixes this issue?

MrMuppet · September 16, 2021

Unfortunately I believe the version we run is the last version released, such a shame because it is a very popular map on the server, @kemon is this in your workstream?

lost · September 28, 2021

Hello

From yesterday something strange happened on the main server. I had all the time ping around 50 and right now periodically it is jumping to about 80 and lowering again to 50. This is not problem with my connection because I checked it. I checked if this happening on the other server and i dont have any problem on other servers from TM. It does not depend on the number of players. It is happening all the time right now. Can someone restart server or something?

MiniMuppet · September 28, 2021

we updated the new build yesterday so not sure if thats related. Try the german server see if its the same 46.4.80.110:27960

lost · September 28, 2021

I checked it, on german server problem does not exists, only on main server

MiniMuppet · September 29, 2021

must be how your routing to France then, the set up is the same on both servers.
