Everyone,
If you play a game and get lag, check which server you were playing on. You do this by going to the following path on your computer:
C:\Riot Games\League of Legends\Logs\Network Logs
and checking the most recent named network log. It will look something like this:
Sat Jan 12 22:53:35 2013: LogOut_File: : logfile started
Sat Jan 12 22:53:35 2013: Net Status: low-level initialize success.
Sat Jan 12 22:53:35 2013: Note that this new version (12/19/2011) has reduced the frequency of updates so the numbers will be larger
Sat Jan 12 22:53:35 2013: time = time of logging
Sat Jan 12 22:53:35 2013: address = address of IP address
Sat Jan 12 22:53:35 2013: incoming = total size of messages set to me in bytes. Spikes can indicate lag.
Sat Jan 12 22:53:35 2013: outgoing = total size of messages set from me in bytes. Spikes can indicate lag.
Sat Jan 12 22:53:35 2013: app_ctos = client to server bytes delta excluding overheads (app data only)
Sat Jan 12 22:53:35 2013: app_stoc = server to client bytes delta excluding overheads (app data only)
Sat Jan 12 22:53:35 2013: loss = number of packets lost. Can indicate lags. Some node on the network is dropping packets or taking to long and we have to resend them.
Sat Jan 12 22:53:35 2013: sent = number of packets sent. Spikes can indicate lag.
Sat Jan 12 22:53:35 2013: ping = how long it takes for a packet to get back and forth. Spikes can indicate lag.
Sat Jan 12 22:53:35 2013: variance = how much the ping is changing from avg ping. Spikes can indicate lag.
Sat Jan 12 22:53:35 2013: reliable delayed = This occurs when we drop reliable packets from sending this frame because we are sending to much data. Unreliable are more likely to be dropped than reliable.
Sat Jan 12 22:53:35 2013: unreliable delayed = This occurs when we drop unreliable packets from sending this frame because we are sending to much data.
Sat Jan 12 22:53:35 2013: app update delayed = This occurs when the app is taking to long to run code caused by network packets (ie CPU) and packets are delayed until the next frame
Sat Jan 12 22:53:35 2013: Time spent in critical section (frame) = This is the time the network thread is blocking the main thread from doing anything.
Sat Jan 12 22:53:35 2013: [time], [address], [incoming], [outgoing], [app_ctos], [app_stoc], [loss], [sent], [ping], [variance], [reliable delayed], [unreliable delayed], [app update delayed], [Time spent in critical section (frame)]
Sat Jan 12 22:53:41 2013: A new client connected from 216.133.234.155.
The IP Address in bold is what you should post to help out the devs the most. You could also attach the network log to your post by using the advanced editor. I attached a sample network log for you to make sure you've got the right file.
Hope this helps expedite the process!
