Title: Speedtest and Packet Loss Issues
Post by: _AH_Olds on January 15, 2009, 09:52:13 PM
I did some testing on my connection, per Foxbat's suggestion, to try to determine the cause of the surging I've been getting of late. I ran a test on a server at Stanford, http://netspeed.stanford.edu/ (http://netspeed.stanford.edu/), and at the University of Michigan http://speedtest.umflint.edu/ (http://speedtest.umflint.edu/)and found out that there was packet loss. My cables were good, but I don't know how to fix the problem. I can't copy the report for some reason (a Java applet)  :unhappy-059:, but here is what it says in a nutshell:

"Excessive packet loss is affecting your performance, check the auto-negotiation function on your local PC and network switch." It gives a lot of other cryptic information, including that packet queing is detected. I don't know much about packet loss, and am not sure where to look to fix it. I can go over this with someone more knowledgeable if necessary. I'd like to fix this problem, as it is affecting gameplay.

Thanks, and S!,

Olds

S~.

Try unchecking the check box for QOS Packet Scheduler.

( Control panel, Network Connections, Right click your connection, properties, uncheck the box, ok.)

When you click ok you will lose connection while windows makes the change..you  should reconnect right away.. once reconnected, re run the speed test..

if you don't reconnect , reboot.. if you still can't connect.. go back and recheck the box...

it may or may not make a difference..but it couldn't hurt to try it.

Ok, thanks, BBQ, I'll try that when I get back. I'll let you know how it works.

I don't know about those services you used, Olds, but I would try this:

Go to start > run > cmd.exe
type
pathping google.com

Wait for it to finish... (should take about 6 minutes)

Let me know what percent packet loss you had throughout your route.

I did the test, and in a nutshell, when the trace got to Google, it said 98% loss (twice). Nothing else anywhere in the test. Not sure what that means. I took a screenshot and pasted it to the clipboard in Open Office text, but I can't get it to post as a pic. If you want, I can send you an email.

Thanks, and S!

S~. turning off the QOS scheduler will not reduce packet loss. but turning it off does release the bandwidth it holds in reserve.

Hmm.. That email looks fair. One of the hops you had problems with blocked pings anyway. (were they indicated with 3 stars * in the first block of output? I couldn't see.) 

Can you do two more one to yahoo.com and another to msn.com? I want to make sure you actually have bad packet loss without just looking at one occasion. Generally any loss > 2% is bad and 5 direct point hops (3rd column) had 2%. Doing another two to different places will make sure it's not just an anomaly.

If the tests you ran said you had high amounts of packet loss, I'd like to see that output because I don't see that indication in the test you just emailed to me. If there were a problem with your computer, you should see more consistent packet loss regardless of the pinged location, not just select hosts. Also, have you run those tests on other computers?

That was what I was told to look for, in order to resolve the surging problem while in flight. Apparently, I don't have a packet loss problem. Wonder what else could cause the surging?

I'm not familiar with 'surging'. What's that?
Title: Re: Speedtest and Packet Loss Issues
Post by: _AH_Duff4r on January 25, 2009, 05:54:50 AM
Surging is where the plane (Olds) moves back and forth as it going forward through the air.  It is also called a stutter etc.

Olds....

Read ALL of this: Anti-Stutter (http://il2ultrapack.net46.net/index.php/topic,2.0.html) but back up your conf.ini  You Been Warned!

Don't quit till you've read it.  Sorry it is long!

Post by: _AH_Olds on January 25, 2009, 01:53:42 PM
WOW!  :surprised-041: That's long! Not finished reading it yet, but already got questions. I found something weird in the config file for the Process Affinity Mask=2. It looks like this:

[rts]
;ProcessAffinityMask=2

Is that supposed to be there? I seem to remember doing something with that, but don't remember what. Also, what about the water and shaders set to 0? I don't have a problem on this end with the graphics...it is very smooth. I think the problem is in the online part...what everyone else sees. Would my graphics settings affect online play?

I'll try to catch you online when I can to go over this. Thanks for the help, Duff4r!

How is surging different than lagging?

Hornet:  It's the Southern form of the Verb "To lag"

Olds: you remember that because if you want to use Prioaff or Process Lasso you must remove (;) from that statement like this:

[rts]
ProcessAffinityMask=2

Then save the conf.ini file

Hmm, well lag could be caused by a variety of problems, including packet loss. But I doubt packet loss is at fault here.

Olds, I know you've done speedtests before, but post yours here so I can take a gander-

S~.. i've always thought that Lag had a double meaning for us..  we use it as  a general term that refers to all kinds of interruptions in the smoothness of the game play.. and also a specific video effect.. 

.. which is a plane seeming to hesitate and then a quickly zoom to where it's 'supposed' to be.

whereas the surging looks like a plane  is speeding up and slowing down almost like it's on a slow motion  invisible bungee cord. kinda reminds me of the motion you see in those countertop wave machines.

Title: Re: Speedtest and Packet Loss Issues
Post by: _AH_Duff4r on January 26, 2009, 05:20:27 AM
Sorry Olds....It's WAY below T1.  You're showing a bit above 1 Meg down.  My guess is you are paying for 1.5 Megs down.  As I remember your getting it wireless correct?  As in off a tower?  Not coaxial all the way?

Remember this...It's not what you have it's how solid it is!   Oops?  I am I starting to sound a bit Jackish?

If your hitting a tower that's where the packet loss comes in.

Regardless, I'd put this topic to bed as there ain't squat you're going to do about it and I think it depends more on who hosts...

Example DealinDave's host pure sucks for me.  I'm in Idaho and he's in Florida.  Yet, Jack's is rock solid as in better than Skat's and BBQ's.  Fox is pretty good for me depending on the night.  Just depends.

If you remember back a bit, Gonzo was always telling me "hey bud your doing that "thing" again.  He was referring to the same thing you're talking about.  Another thing.  To me you're solid I never see you oscillate....Go figure.

Don't worry, be happy, and fly!

FWIW

Olds,
Yeah, you are below a T1 (but not by that much, 'cept for your upload).

I'd say you don't have packet loss so much as you have variability in your connection. This is the nature of residential connections and especially wireless. A close friend of mine works tech support at a wireless ISP and I think he said that the towers act a lot like cable internet - when neighbors are using the internet, your throughput degrades.

Since (I would suspect) that your speeds are on the low end of what's required to play IL2, I would say that the surging you experience is due to the variation in internet speeds you're able to get.
Title: Re: Speedtest and Packet Loss Issues
Post by: _AH_BBQhead on January 27, 2009, 03:30:56 PM
S~.

T1..  1544 kbps.... 1.5Mbps
T1c.. 3152 kbps.... 3.1Mbps
T2..  6312 kbps..... 6.3Mbps
T3..  44736 kbps... 44.7 Mbps
T4.. 274760 kbps.. 244.8 Mbps


mmmmm T4......

Title: Re: Speedtest and Packet Loss Issues
Post by: _AH_Hornet on January 27, 2009, 04:25:26 PM
I don't even think you can get T2 and T4. I think you have to buy multiple T3s or move to OCs

OC3 - 155.52 Mbps
OC12 - 622.08 Mbps
OC192 - 9953.28 Mbps

We had dual OC192s between the two datacenters I worked at over the past summer.

Nope if you get "hicksville" enough like me you can.  I have T2 In Blackfoot, Idaho  I do see most of it always 5.4 to 5.8 with 500-ish up.

A true T connection would be symmetric. Maybe it's possible to pay for fractional Ts to get asymmetric speeds. A standard or fractional T1 by itself seems pretty useless these days unless you're running phone over the channels or something. Nonetheless, they still cost like $350/mo. Extremely high availability (High SLA) and the fact that they don't bawk when you use a lot of bandwidth differentiates it from basic DSL.

I guess it must be the quality of the electricity up here in Canada that lets me host without any problems.... :happy-112:

I shouldn't complain though, I normally get over 8 Mb/s download speed and better than .55 Mb/s upload speed (at night) when I am online ....
