Q u o t e:
Hmmmm 6000 views of this post and still no blue response.

We don't neccessarily need you to fix the problem right now - just want an indication that you are aware of the issue and you are working on it.

Or maybe the WOW population outside the US and Europe aren't that important

Hear hear!!

Comeon blue!!

Q u o t e:
OK the VM / Linux stuff has proved unnecessary!

---

This was discussed earlier on in the thread I think.

As mentioned, this is ONE solution but not the ideal solution. This effectivly disables "Nagle's Algorithm" (http://en.wikipedia.org/wiki/Nagle%27s_algorithm) for your entire machine and not just one particular application.

While the TCP_NODELAY can be beneficial for online gaming (In this instance), it can have serious impact on other network applications. Things like network file transfer and downloading can be slowed to 50% of their normal speed under some circumstances.

The idea behind the VM ware or linux box was to limit the changes to the traffic which would benefit from it (ie WoW)

Though your information is useful, you might want to hunt down the post which pertains to the windows update patch you need to apply to make this registry hack work under vista and modify your post with the relevant instructions.


--d

Just a note.

Iptables will not automatically save the rulebase to be applied on boot. Depending on your flavour there might be a firewall script or wrapper (SysV).

Just echo the commands into a script (make sure permissions are to root/boot only) and call it from a startup script (like bootmisc.sh or networking, check in /etc/init.d/* on most systems, or rc.*).

Thats if you want it applied on bootup, if you dont, just execute the script before you want to play WoW.

Apologies to those who already know.

Oh also,

If they haven't replied yet, then I am assuming they are investigating it, or have escalated to the network engineers.

The optimist in me thinks it will get corrected next patch.

if a player has this one PC mainly used to play WOW, then the registry fix is much easier to do for average Joe. you can always delete the registry entry, or modify the value to 2. only require a restart.

but if a player has several PC laying around, it'd save more trouble in the long term to set up a linux box to route WOW traffic with nodelay.

bump for Blue.

Agreed, hopefully Baalzaman will update his post with the vista information and keep the information in the one easy to access post. I am sure it will be usefull for alot of people.

i'm wondering too if Microsoft will get upset at a link getting posted. Hmmm.
Perhaps its punishment for running Vista :P

---

Q u o t e:
Has anyone been able to implement this on a Mac? Please advise.

Thanks

---

Kinda... I pasted in a system-wide treatment based on comment in original post, rather than iptables fix.

To save you the effort of finding it:

Launch Terminal.app (in /Applications/Utilities)

paste:
sudo sysctl -w net.inet.tcp.delayed_ack=0

Enter an admin's password when prompted.

Restart your Mac.

Have Fun

Q u o t e:


This is what I get when I type in ps aux | grep soca
5063 0.0 0.1 2984 764 pts/0 R+ 13:44 0:00 grep socat

A friend said the rc.local only handles 1 line commands.... I don't know what that means.. so how do i fix this sucker?

NXZ how do i reckon the error messages, take not I only learnt how to use Linux/Ubuntu yesterday
what command so i use to check my error messages?

---

Ok what tells me is that socat isn't running. Make sure you copy and paste the EXACT line that works in a regular console into your rc.local (without the sudo and an added " &" though obviously...) It works fine for me, and I'm using Ubuntu also so you shouldn't have any problems. Check that word wrap isn't enabled in whatever you are opening it with and that it's all on one line (ie hasn't wrapped to a second line).

---

Q u o t e:


Sadly the patch required that fixes the registry change not having a effect, is part of Vista's SP1 and the patch itself is not easy to find.

It is possible to find the patch, and it does work, but those people on Vista should wait or use another method.

---

For Vista users, you can download this hotfix from here.

Vista 32 bit - http://thehotfixshare.net/board/index.php?showtopic=3265

Vista 64 bit - http://thehotfixshare.net/board/index.php?showtopic=5976

You will have to register on that site to download it, but it is free and I have never received any kind of ads or spam from them. Pretty good site for Windows hotfixes that are generally unpublished to the public on any kind of widespread basis.

Cheers.

Cheers Dedrin!!

Yeah I checked everything in my rc.local and it was all correct (no sudo, has a & at the end), the PC i'm running ubuntu on is an old 700Hz PC, could that present a problem? maybe its a bit slow and doesn't load fast enought to run the socat command?

Maybe I need root access or something? because when I'm in Terminal and I run the sudo socat command I'm prompted for my password.?

I've been google abit, maybe I'm ment to put the commands in /etc/init.d/rc.local instead of /etc/rc.local?


heheh sorry for turning this into a linux help thread, but god I'm loving linux ubuntu ever since I installed it two days ago.

I have an old P3 500 with 128Mb RAM just begging to have linux installed...I usually only have between 100 and 200 ms latency, but I think I'll try this just the same to see if there is any difference. If there is, I think I'll donate the computer to my cousin as his ping is usually around 1k. I really hope it works because it would do him a lot of good. Thanks for figuring this out and I'm looking forward to trying it.

Its in your hands Blizzard, what's happening about this now fully proven real world bug?

btw people, there is a java script fix floating around. I was lucky enough to grab it, but can no longer find the link! That might be a good solution for now, other then VM. If its fixable with a java script, its definantly fixable by Blizzard. I wish a bluey would have replied by now :(

To all who have thought of this THANKYOU THANKYOU THANKYOU from a very grateful Aussie!

@Baal

Sorry to be a bother but is there an easy way for the VM / Debian setup to run all the ip table commands etc on boot? I'm a total nub with these things but got your setup working off a Laptop on my network.

Cheers in Advance

another bump to increase the length of the post and maybe get a blizzard response

great work from the people involved in cracking this nut. pretty sad that it has taken over three years to find and now that it has blizzard seem happy to ignore it without even a comment.

This is excellent! Well done, Yarre. I'm a little disappointed that Blizzard immediately shoot down an idea that allows Australian/Oceanic players to have the same gaming experience as those in America without investigating.

[sarcasm] Well done to Bliztard for responding to this 11 page thread so promptly! No, but seriously, they must be too busy responding to important threads such as this one https://forums.worldofwarcraft.com/thread.html?topicId=3271125333&sid=1 [/sarcasm]

A blue can say 'Good morning' to someone but can't congratulate or comment on a post that may change the gaming experience for thousands over WoW? It's disgusting.

Again, well done, Yarre.

BUMP!

Blizz please investigate this asap and reply. Your loyal fans here has been tortured 3 years with red latency.
Do you not love us? Save your fans, will you?

How many replies do they want?

LETS GIVE'EM ALL!

I'm from Brazil, and this simply cut my latency by half! from 400, to 200..

BUMP BUMP BUMP!
