Good evening everyone
We will be carrying out a fairly significant network optimization tomorrow morning at 6am, which will have no impact on the average customer, but could raise some questions with our heavier Peer to Peer users. In light of this I wanted to take the opportunity to explain this here, before we implement the change and to pre-emptively address some of your concerns.
As you know we've been carrying out an ongoing investigation into the source of high latency problems experienced in game for our World of Warcraft players. Part of this investigation revealed that there was definitely a relationship between the increased allocation to P2P and the increase in latency at certain times of the day. Closer investigation of the possible causes of this revealed the fact that the more aggressive P2P protocols generate an extremely high volume of simultaneous connections through some of our core routers and this is placing an unnecessary load on these devices.
Our finding has also been that some extremely aggressive settings are in use out there, effectively trying to brute force a few extra KB out of the traffic manager and we really need to curb this practice.
We have therefore decided to implement an initial limit of 100 simultaneous connections per customer on P2P protocols. Depending on the positive impact this has on network performance we may further reduce this in small increments until we find the right level.
I have carried out tests on bittorrent, self limiting at values between 200 (the default on utorrent) and 50 and did not detect any significant changes in transfer speeds on well seeded files.
We therefore believe that this is a very reasonable number and it should not be seen as an attempt to limit transfer speeds on P2P.
I cannot provide any guarantees that this will be a solution for the World of Warcraft issues, however it is certainly a very necessary network optimization and one that we believe will provide a better experience for all our customers in the long run.
Kind Regards
Will
