Disconnects when running multiple characters

[johnbb]

First of all, I am no network expert. All of what I am saying here is what my brain came up with after listening and reading a bit.

When I want to run multiple toons doing some trade runs or something, I seem to get more disconnects entering stations or gating. It seems like most disconnects may be associated with loss of UDP protocol packets somewhere in the chain between the client and the server (potentially somewhere within the Internet as well). I thought about it a little and wondered whether there is anything on my end (client) that I can do to reduce the occurrences.  On my PC, Windows has a single buffer receiving the UDP packets and I thought that multiple instances of the client would be trying to receive multiple packets pretty much all at the same time. If this buffer were small, the buffer may overflow from time to time and therefore generate some packet loss on my PC. So I decided to see what I could do (raise the size of the buffer). I went into Control Panel - Devices - Network Adapter - Properties - Advanced - Receive Buffers  and then changed the size from 1024 to 2048. So far, I have not had any disconnects. I expect the value of the Receive Buffers on many PCs will be different depending on the resources available.

 

Remember that this is totally just what my brain came up with based on all the information that I have heard. It may or may not resolve some of your issues.

Hi Johhnbb,

 

An excellent suggestion however; not all network adapters support this feature especially the lower end onboard ones.

 

On my ASUS x99 mb it does and the default is set to 256 (which is fine for most cases) since I have inexcess of 32Gb Ram buffreing is not an issue and yet I too suffer from similar issues just like you guys. Out of curiosity I have increasted mine to 1024 (4x the default for it) just to see if it makes any difference.

 

As of this reponse the server has been restarted some 5.5hrs ago so there should be minimal issues however I am seeing already 6 "ghosted connections" of the 90 avatars listed as active which is not normal following a restart.

 

I will keep you posted of my findings though.

 

All the best,

Hi Johnbb,

 

I just did some googling and found this : Tuning Throughput Performance for Intel® Ethernet Adapters

other maufactures may reccomend other values though.

 

All the best,

Thank you Yeti for finding more information about the network adapter settings.. I have a higher end machine and lots of RAM so the change I did will likely not impact the performance of my machine at all. However, it quite possibly won't help the disconnects either. I just thought of it as one possibility for reducing the frequency of disconnects.

Thanks again for following up.
