Leatrix Latency Fix

Well usually I use a private SSH server to get good latencies, but never had this low before.
25mans seemed fine, latency does go up in a very hectic AoE fight, seen it go up to 483ms whilst in the middle of the fight, but actually at that point my pc slowed down on the GFX, mostly because I have settings high enough to work most of the time but not in chaos. So I can not comment on whether the latency went up because of the fight/isp or my actual pc, as that will influence the latency too. What I can say is this: 0 disconnects!
Yes it was on sunday, as CS only did their maintenance over to SAT3 on Sunday morning.
Was fine in Wintergrasp, and Wintergrasp is HUGE. Dalaran was fine. Had 0 disconnects whilst doing pvp and wintergrasp so I do not see the issue, I just took a screeny of the best moment while I was thinking about it.
You don;t like the example, just ignore it rather. I'll enjoy this ISP's good days while it last. Why? Because it was the 1st time in 2 years I could play wow directly over my ISP without using a SSH proxy/tunnel or VPN to keep latency low. In fact my experience Sunday on Cybersmart was better than all the SSH tunnel/proxy and VPN providers I usually use to keep my latency at around 350ms.

Will do when I do a 25man again, I don't do them much as I joined my guild as a casual and really do not have the time to join their 25mans on a daily basis. Only 25mans I do is pug VoA's and thats not really a test, I;'ve never had a problem in VoA before.
how about a WG screenshot mid combat?

I am using the new Webafrica test trial accounts and the latencies are damn good for a shaped account. I am playing at pretty much 290 / 310 ms in mid dalaran with no proxying involved.
When I raid I still switch to my unshaped.v account...
I am very curious about the cybersmart accounts... does sound promising.
They also route via SAT3 ?

Thanks... looks very promising.
Gonna order me a 1 or 2 gig account, and try it out.

On Sunday I had latency of 230ms in quiet places, and most BG's, using AXXESS unshaped (SAIX), which costs a slap-in-face R100 a GB.
But, the cost is not the point, in the 25 man Onyx and the 25 man TOC which started at 21H30, the connection simply could not keep us both connected at the same time, and during heavy combat latency would shoot up to 450 - 530ms.
When one of us dropped, usually me, the other would stabilise at 470ms.
Now, here's what I don't quite understand: I run my connection from both machines through a linux server (which means that I can monitor the data transferred), and the rate of data transfer during a 25 man boss fight does not exceed 45kB/s to the internet and 210kB/s bits from the internet, with both of us connected and fighting and vent running.
So, what I would like to know is: Where the heck is the congestion happening that forces one of us to disconnect when lots of AOE is used? The ADSL line sure as heck is not being used to capacity, so .. what is the real cause?

I bet you a case of beers that if I borrow my neighbour's ADSL line, and I play on his line and my SO plays on my line that neither of us will be disconnected.
2 Ports on the same freaking DSLAM.

I'd say the starting point is, there are 2 of you on the line both with vent, where as in my case it was only 1 person. 2 players mixes the scenario quite a bit.
Do you also get disconnected when only one of you play?
Personally SAIX unshaped never gave me smooth gameplay on WoW, which is why I just got myself shaped accounts and used SSH tunnel proxies which gave me better results almost always.
Now I do not know how stable your line is, but 45kbyte/sec outbound is a lot, even for a 4mbit line because your upload is still low, 512kbit I think? Theoretically if you lucky you can max do 50kbyte/sec on that, so basically your upload is getting maxed out and that is why you get lag spikes and disconnected in those instances.
Try having a shared vent session, but if none of you are talking vent doesnt do much outbound traffic, I'd say its the 2 of you both sending too much data to the wow server at that point in time.
Now in your case, a SSH session with compression turned on (zlib) would greatly help because it will need less speed to send the same amount of data.

The DC's are quite common and nasty to sort out.
After extensive debugging and reading up literally on packet level I got mine sorted out (well all except Ony 25 when all whelps are AOED down in one big massive pile). The thing thats killing you and causing DC's is actually a combination of two things. Mods + heavy data bursts.
The first thing you have to do is elliminate all non-critical data transmissions from your pc. The following sorted out my DC's.
1 - Get FuBar_AddonSpamFu
This will identify who is bombing you with data requests and causing your pc to choke on data bursts when it comes to heavy raiding encounters which pushes the data transmission over the edge which kills your connection to the server. The following was identified : a data rate of 3000 CPS will cause a disconnect if sustained for more than a few seconds. There seems to be an input buffer of something along the lines of 32KBytes serverside. Filling it would be what causes the kick. Now normally you wont DC under normal conditions. But add severe syncing conditions as per a 25 man raid, and boom you hit the limit and get DC'd.
Now before you reply with a answer like "But I DC even while I have NO mods / addons running" ... think about the following.
Your pc is syncing passively with people in your guild, even if they are on totally different areas / locations in the game. Dont believe me ? Get that mod, and see who are the poepholle killing you... yes its those people with Gearscore checkers, carbonite, questhelpers, auctioneers. Your pc syncs to them at least 20 - 30 times every 10 seconds PER PERSON. Add a few guild members like 10 / 20 of them running it... well yes, not rocket science.
Mods... I used DBM in the past, but after just seeing how much DBM sync's... I moved over to big wigs. The difference in data syncing is remarkable.
Disable your combat log totally.
Recount ensure you use /recount sync to set it to lazy mode syncing. Real time syncing under heavy AOE environments will kill you with data transmissions.
2 - Download and install chat throttlelib : http://www.wowwiki.com/ChatThrottleLib
You can actually channel your addons to communicate through that mod to ensure you dont DC under heavy data burst periods.
I went from guaranteed DC's in TOC Gormak +twin valkyrs + Anube every week to pretty much not one DC whole night.
Oh yes... to stop your pc from syncing with other people you can /ignore that player and you will stop communicating with the other player.
Addons like gearscore checkers are banned from high end raiding guilds... the authors of those mods should be given a painfull death with no mercy.

Very interesting, I can agree with this after looking at davemc showing that 2 pcs are doing 45kbyte/sec upload!!
Definitely makes sense when I put 1 and 1 together. It also probably then makes sense why I don't get DC'd ever, since I only run very specific addons and usually addons that dont too much uploading except from maybe DBM/recount/omen, however I tend to disable teh sync functions and instead just set my combatlog range very far so that I can gather whatever I want myself.

Not sure if its leatrix fix helping but anywhere i go in wow even dalaran gives me 300 ms to 400 ms latency. Yet to try a raid.
Using semi-shaped IS account and get same ping during day also

Ok no WG yet, but have:
VoA 25man - very smooth pug run: http://www.restricted.co.za/upload/WoWScrnShot_102609_200238.jpg
AQ40 with about 6-7 ppl as we were bored, huge aoe here: http://www.restricted.co.za/upload/WoWScrnShot_102609_225019.jpg
If that aint good enough then well I dont know what is.

Not bad, I'm happy for you bud. Enjoy it. Cybersmart is just a bit expensive still.
Maybe not compaired to a Telkom Unshaped acct, but in general.
Atm I'm still on Afrihost+lowerping (costing me R155 ofr 3GB) and I'm sitting with a +- 280ms BUT it does spike sometimes which gets me back to the fact that when raiding seriously I only really trust Saix Unshaped+lowerping, thou maybe I can try Cybersmart.
I wonder if that might even give me a lower latency...

well all 3 methods gives me less latency be it leatrix, linux box method or something like lowping/gamepath.
but going to have a look at Pornolio's anti dc post

chatthrottlelib isnt an addon that you install btw. It's a library you use to send messages across clients in the code of your own addon that you have written. So whether your addons do, or do not use chatthrottlelib really isn't up to us.

Only one of us runs vent.
With only one playing in a 25 man, no DC's.
Thanks for the other pics Tinuva. That 25 man VOA is extremely impressive, I am tempted to ask if you flew up to Europe for that.
@Pornolio - good tips, I shall be trying them soon. I will report back.

Alright the spam addon was interesting to see, although I could not find real problems with it, I have seen a guildy with some gearscore mod that sends an insane amount of messages to me, so just ignored that person from there onwards.
Hehe I wish I could experience internet in Europe, but alas that was in fact from SA. Some more pics:
Onyxia:
Whelps in 10man = 281ms : http://www.restricted.co.za/upload/WoWScrnShot_103109_152034.jpg
Whelps in 25man = 323ms : http://www.restricted.co.za/upload/WoWScrnShot_102709_194826.jpg
I died in the last one so took a screeny as I died, should pretty much still show the latency I had while attacking them.
Anyways, I read that this Cybersmart over sat3 is just temporary until they move back again to using Seacom, but I really hope at that point the latency will be similar over Seacom. /sigh lets hope
ps. I am done now posting these.
