Very high latency to router: game server

Question

dafin0    53

Maybe not the normal type of problem that is talked about here, but I have no idea where else to ask for help.
 

I run a game server (Rust), when we hit a player count of above ~125 we start to get really high pings from the server to the router (see picture)

At lower populations our pings are for the most part under 1ms.

Here is the server setup:
Windows Server 2012R2
8GB RAM (at most 3.5GB in use)
120GB intel SSD
i7 4790k
Intel I350-T2 NIC (latest driver)
Dxdiag: http://pastebin.com/Z073aVj0
Net speed test when not under load http://www.speedtest.net/my-result/4229282620 

The Rust server is capped at 100FPS, at this rate the CPU usage is at the very most 15%

Sadly at this point I don

Your speed test is not working. 

 

So what is the utilization of the network, and what is your speed?  Ping times and loss are sign of saturated link and sure ping will get dropped first, etc.

Well if it were a high end cisco anything, I don't think it would be a router. Whole picture, server and network usage would be needed to determine cause. Could be the poor to the server is saturated, could be the network card can't handle the congestion. Could be your high end cisco is really a linksys that has huge hardware/firmware issues. Btw, high end cisco is an asa appliance. They start in the 500 range for a cheap one. I would probably have a 5512 in there at least (way over 1000)

How many channels, connections, and ports are set on the router? If the limit is 10 then it will multitasking them and put connections on hold as it round robbins them

Sorry this speed test should work http://goo.gl/0Tbiqs (not under load) goo.gl/W2p1dK (when under heavy load and having ping issues, other computers are same network are fine). Right now Windows resource manager is showing 0% network utilization but with that said its early morning here and only 20 people are on.

here is a picture task manager from when we were getting hit with the high latency http://i.imgur.com/C3eJChG.png

I have seen the model cisco ASA 5520 said in the past so i believe its running through this. what would you recommend to track network usage? i have to appolgises but im not the greatest at the networking side of things let alone troubleshooting

Sorry i couldnt really answer this because i dont have login rights to the router, i pretty much ask for anything i need to be changed router side and wait for someone else to do it... ill see what i can find out.

So what are you suppose to get in connection speed.. If 100 that seems a bit low end..  Your at gig right?  Or just 100mbps connection?

 

So what else is on this router..  If you not using up your local connection, and just pinging your gateway shouldn't really be a problem unless that router is busing doing other things.  If your server is under load (prime time I would think) then other boxes on that same network prob all busy as well?

 

Here me pinging my local router while doing a speed test maxing out my internet connection both up and down..  But since that is really just a fraction of my lan speeds, should make for any issue.  I saw 3 pings not under 1ms for the whole speed test up and down.

LAN is gigabit and WAN is 100mbps
The router isnt under much load with just basic web browser use most of the time.
If i ping from another computer to the router the pings are normal and Internet bandwidth is normal as well.

i found out a bit more about the network setup. it goes Router -> switch -> server
in the next two days we will set it up to go Router -> server and try the onboard NIC
the thought of that is to see if we notice any difference at all, and from there we can see if its the switch, NIC or driver. if it still plays up after doing all this then it would come down to a Windows setting and or the Router.

I wold bet large sum of money it has nothing to do with the switch..

 

You sure its just not your machine not processing the pings because its busy with the game?  Are users complaining?  doesn't look like your bandwidth is being touched from pic you sent under load.  So what happens when you do say a speedtest and ping your router, like I did.. So you see issue then?  So can you ping the router from a different machine?  If the router is busy should show the same slower pings.

 

Now you will see issue pinging outside lan out the pipe that is full..  So my internet is 50/10 I see normally 60/12 - so if I do that same ping but to my isp gateway..

See the pings go way up when I fill up my pipe..

Im at work at the moment so ill just give you the details i know off the top of my head.
Players do notice as soon as we hit this latency brick wall.

 

Ill test out the pings while doing a speed test tonight

Maybe you want to send some of us, PM maybe the IP and we can test latency from our different networks.

I have servers all over the US I can test latancy from, LV, Dallas, FL, Chicago, And then have one EU, luxembourg..  And can bring up more in other locations as well, Atlanta, NJ, etc.. etc.

 

Send me the IP and can setup smokeping to monitor them.. So you see something like that - can give you the url you can check with.

I could set those up from any one of my servers.  So you could see any issues for difference in latency from different parts of the country.
