BT Infinity Latency Issues for Gamers
Ok well after 2 months of getting BT Infinity installed, (due to admin problems), all is working great. Getting Bandwidth of about 30Mbs great.
The problem is online gaming, you need split second timing to play the game, so that means low latency.
Over 2 weeks or so its got worse and worse, 150ms and above it is un-playable online. I am getting on average about 250-300ms at night, gaming.
On my old adsl wired bt broadband I was getting on average 45ms. This was on my old system.
I think the system is trying to optimise for maximum bandwidth, and therefore comprimising on latency.
There must be a way technically to optimise for low latency at the expense of bandwidth.
I have raised and call and managed to fight my way through to Tier 2 support, (at least they understand the terms I am using yay). There are other gamers with the same problem, and there is an investingation this week.
If there is no solutions then its back to ADSL wired 3Mbs broadband for me but at least I will get 50ms latency.
Will keep you posted, this will be a big blow to BT Infinity for online gamers if they cant fix it
Cheers

Hi there,
I'm just tossing my £0.02. Have you considered that there could be congestion at your exchange/gateway?
I had Infinity installed on Friday (I'm on the LNADK exchange) and below is the ping/jitter test that I did about 10 minutes ago.

Hi,
We have a latency issue relative to voice traffic and we need your help to lower the latency.
Here?s the situation:
we have a Cisco router (c2801-entservicesk9-mz.124-8.bin) connected to an agilent hardware that?s a traffic generator. The Cisco router is an access router for customers who are connecting to the ISP. This access router needs to apply marking and shaping for different products that the ISP is selling. For example, we have a multimedia product that needs to service both voice and data, please look at the policy named ?product_MUL_128?. When we use the traffic generator to simulate traffic for both voice and data we get latency of 50ms for voice while both equipments are directly connected. This is not acceptable for our customers since once we add others equipments the latency might end up being over 200ms!! . He?s the config on the router:
policy-map product_MUL_128_sub
class VO
set dscp ef
set cos 2
priority 45
police 50000 4000 1000 conform-action transmit exceed-action drop
class D1
set dscp af12
set cos 5
bandwidth 51
class class-default
fair-queue
random-detect dscp-based
set dscp default
policy-map product_MUL_128
class ALL
shape average 128000
service-policy product_MUL_128_sub
We believe the problem is due to the shaping we?re doing on the router to limit the BW the customer can use. Please let us know how we can improve the latency taking into consideration our configuration.
Note : when we use 'shape peak 128000' for example it shapes on 256000 (because peak = cir * (1+be/bc)).
Regards, Ahmed.Try toggling wmm settings on client.
disable powersave on client, if not already.
to eliminate client side issue, try with different model client.
if 2.4 used, disable all lower rates.
fyi, ping traffic on WLC is considered best effort. -
Infinity latency issue (Evening) - NI
Hi all,
I am currently having issues with our Infinity with regards to our ping/latency (I see other forum users are not that far off with related issues) and any help would be appreciated. The issue has being ongoing for the last few weeks causing online gaming to become hugely frustrating as a FPS gamer. Our Infinity is FTTC only with Copper to the house with the BT cabinet located on the street behind us (Aprrox. 300 yards) and currently run a Homehub 2 with the Openreach modem on the unlimited Infinity package (2?).
I have being monitoring our ping over the last number of nights, and as like a few other forum users, my issue seems to arise in the evening so far - 6:30PM onward (I will have to monitor weekends during the day and night).
Ping to UK and EU servers used to be great, always on the good side of 35ms. Now, EU servers has turned into a lag fest after 6:30PM and my ping can be anywhere from 70/80ms to 120ms depending on the night and UK servers has crept up to around 50ms and a bit more at times.
I have done the BT wholesale speed tests and the results are below:
As an example below is a trace route done on a COD German server done before 6:30PM tonight:

Hopefully I haven't left anything out.I know this isn't what you are going to want to hear, but BT are responsible for everything up to roughly hop 7. Hop 8 could possibly belong to BT but hop 9 appears to have crossed into the ownership of dtag.de (Deutsche Telecom). This probably means the problem is either the link between Deutsche telecom and BT, or more likely, a problem within Deutsche telecom themselves.
I don't think BT will be able to help you with this.
When you are getting the issue on the German COD server, can you try quitting and connecting to a UK COD server to see if you have the same issue. I am fairly certain you won't have the same problem as you won't be routing through the faulty equipment.
I noticed you also mentioned above that in the evening the UK servers creep up a little. Can you try using WinMTR to run a trace and post the results in here. Should also help identify where in the UK the issue is happening. -
Latency issue where there was none before 9.1.1 upgrade?
I can't understand why Logic now has a record latency issue for my setup, (nothing at all has changed other than an upgrade to 9.1.1) where last startup using exactly the same setup there was none.
Is anyone having similar latency issues?
I have done everything, turned LLM on and minimised my buffer etc and yet I still get a recording that is lagging by a half beat.
Why would this be?
Message was edited by: shotsi673Possibly check to see if recording delay has for some reason been added? It's under PREFERENCES > AUDIO > DEVICES > CORE AUDIO

What interface works best for GB? NO delay, latency issues please!!!
What is the best way to record electric guitar or a microphone (for acoustic & vocals) into Garage Band? I tried plugging directly in to the mic input and selected low latency but there still is a bit of delay. I assume I need a USB or firewire interface. What are some good ones that are ultra portable? This is for the road. Thanks for reading.

wouldnt getting a super CPU fix latency issues? even if it did have to be routed through a thousand places, a fast processor could get it done without latency issues, no?
Yes and no!
First, Garageband gives you limited ability to change the size of its buffer, which impacts latency. So even if your CPU were fast enough, I'm not sure if GB would allow you to dial down the buffer size in order to fully take advantage of it.
Second, latency isn't only a function of CPU speed. There are other places where the audio can get bottlenecked as it makes its way in and out and through the computer. That's why some of the systems that market themselves as ultra-low latency for professional work use PCIe cards in order to shovel audio back and forth faster than is possible via USB or Firewire. For example, Apogee's Symphony System connects via a proprietary PCIe card in order to offer phenomenally low latency rivaling dedicated systems that use the computer only as a host (Garageband is a native system that uses the computer for everything).
So while a fast CPU is at the heart of the latency issue, there are a number of surrounding issues that also influence it. The workaround of having an interface with its own routing system - so you can listen to your audio as you record before it has a chance to go through the computer and get delayed - is a cheap and elegant, if imperfect solution. -
Time Capsule stuck at Preparing for Backup, and internet TC latency issue
I have an iMac that backs up to my 1TB Time Capsule. I have had it since March. Suddenly it stopped backing up. It get's stuck at "preparing for backup" and never actually completes a backup.
I am also experiencing a HUGE latency issue with my internet connection. I am constantly having to use the 'refresh' page button in Safari.
help....TB,
*_Time Machine May Report "Preparing..." For a Long Time_*
Consider these factors regarding an extended period of "Preparing...". Consider each topic separately and do not attempt to act on all of them at once.
*Recent Crash or Other Major System Event* (Deep Traversal)
The reasons for this process are described in an article by George Schreyer. “During the preparation step it checks the FSEvents log for consistency. If it determines that something isn't quite right it has to rescan the whole disk. This can take quite awhile. A full rescan is always triggered by a crash, an unplanned shut down event or by booting from some other bootable disk between backups…. After a crash, Time Machine must scan the whole disk to determine what it has to do because it cannot trust the information that it left behind. Connected via an Ethernet connection, this phase would typically take 20 minutes on an older PowerBook. Being connected wirelessly stretches this phase out to over 3 hours.” [http://www.girr.org/mac_stuff/backups.html]
According to the following KB article it can sometimes take a very long time if Time Machine begins this “deep traversal” and has to compare data inventories. This may apply to your situation, particularly if many Gigs of data are involved. (http://support.apple.com/kb/TS1516)
*Anti-Virus Software*
Running anti-virus software can interfere with the backup process. Either disable it altogether, or try the suggestion outlined here, “If you use third-party anti-virus scanning software and have issues, make sure your Time Machine back up folder (Backups.backupdb on the Time Machine disk) is excluded from virus scanning.” (http://support.apple.com/kb/TS1516)
*Software Updates* #
Installing new software, upgrading existing software, or updating Mac OS X system software can create major changes in the structure of your Macs directories. Time Machine will backup every file that has changed since the installation.
If you take a look at the Console logs Time Machine may be reporting that your backups need "deep traversal". That's fine. Time Machine knows what is wrong and how to fix it. If you have a great deal of data, it may take quite awhile.
After an OS update (like 10.5.5) Time Machine realizes the system no longer matches what it looked like during the previous backup. So it has determined that it's earlier catalogue of what-should-be-where is 'untrustable'. So it is going to go item-by-item comparing the before and after of your system. If you have just performed an OS Update then Time Machine knows what it's doing - let it do it!
*Spotlight Keeps Indexing Backup Drive* #
It may be that Time Machine can’t proceed or complete a backup due to a Spotlight indexing error. During this period, take a look at the Spotlight icon in the upper right corner of your screen. Is there a tiny dot pulsating in the center of the spyglass? Click on the icon. Is there a progress bar displayed? Generally Spotlight indexing is a good thing. But at time it may hang and never progress, preventing backups from taking place.
Go to System Prefs --> Spotlight --> Privacy Tab.
Drag your Time Machine disk into the window. It should now be among the items to exclude from indexing.
Now quit System Prefs.
Reopen System Prefs and remove ("-") the Time Machine disk from the window.
This should clear out Spotlights cache. Naturally, Spotlight should begin indexing again (maybe even for a few hours depending on how much data there is), but it should eventually stop.
*Reboot Time Capsule* #
Stop the backup from the Time Machine menu.
When the Time Machine icon stops spinning, unplug the TC from the wall outlet.
Wait 10-15 seconds.
Re-plug it in again.
After it has restarted (30-60 seconds), attempt another backup.
Time Machine will report “Preparing…” again, but it shouldn’t be lasting more than a couple of hours.
Let us know if any of the suggestions above helped in your case.
Cheers! -
High latency issue of an evening whilst gaming.
Hiya`s Peeps, Having recently switched to BT from Virgin (this being only my third day as a customer) as the VM service for gaming in my area (Sth Manchester) on thier 50mb package was simply not viable due to over utilisation issues, I now find myself experiencing high latency issues with my BT service.
All three evenings have been lost to me as my in game latency (World of Warcraft) has rose upto 3500ms with occasional disconnections.
Also strange was that was after the BB was first switched on I had a consistent in-game latency of 24ms home and 24ms world, this lasted around 8 hours until I experienced my first lag spike, I was disconnected and when I eventually was able to get back in game, some 20 minutes or so later, my home and world latency had changed to 42/45 (still playable ) but every 10 to 15 minutes the world latency would again rise to around 3k and above and I would again be disconnected from the server.
I do apologise for the lack of any technical detail within this post as I simply do not understand such and struggle terribly with it, I am very happy with both my speed and ping tests, both being excellent in comparison to that that I would see when using the VM service.
What I am after I guess is advice from the community on how to get the best from BT bb for playing my online game, this connection is only used for World of Warcraft and very light reading on the www, I do not have a phone connected to this line and use no wireless connections with it at all, this PC (hard wired) is the only contraption connected.
Any help and advice will be greatly appreciated, Thankyou
Leswelcome to the forum
there is a 10 day training period after your connection is activated during which time you need to leave the router connected with no manual resets. The router may reset (often) during training but that is normal as the equipment in the exchnage tries to find the best stable connection for your line.
after the training period is complete and you have a stable connection then you can get the latency changed to 'fast' if yours latency is 'interleaved' changing to fast can make your line less stable than interleaved but it is the choice of gamers

Latency issue Logic pro 9.1.3.
Hey,
At the same time as upgrading to Logic from Garageband
I bought a Cakewalk Roland UA25EX ext usb soundcard because i was told
i'd have latency issues if i used the caps lock keyboard for midi
or direct input thru the input jack of
my MacBookPro
(5,3 Intel Core 2 Duo 2.8 GHz)
Sometimes i use the caps lock keyboard to sketch in midi ideas and mostly it's ok.
Other times it's delayed and there's no smile on my face.
When recording with guitars/303/generators DI thru the soundcard
I have latency issues that don't seem to be very regular.
Sometimes it's worse than others.
I make sure i have nothing else running on the computer,
just Logic Pro 9.1.3, so it's not like i'm overloading macbrains.
I have tried all the rebooting, i/o buffer size changing (down to 256), headfones from the mac output/headfones from the soundcard/ etc
but still no luck.
I can record with the low latency button on
and it's kind of better, nearly, but that means i don't get to record with the effects on the channel strip
that affects the recording/playing quite a lot, as i'm used to recording with effects/guitar amps if i go DI.
This was the selling point - that i could record DI wthout disturbing Thee Neighbours.
It seems to have gotten worse recently.
I wonder if it's been corrupted somehow because it also has been acting funny when i bounce down -
the play head is set to 1111 and i save - then in the bounce window
the start position says a silly random number and it takes a few attempts of fiddly changes to get it to stay at 1111...frustration!
Is there something i can do or is this normal? -
it seems weird that a Pro app that cost me so much £s wouldn't work in a simple recording/bounce down set up?
or has anyone else had this problem and fixed it?
If i wipe Logic and install again would i have to go from my Logic Express and then up to my Logic Pro upgrade/extension again?
Any pointers would be greatly appreciated.
Thanks in advanceHey Fox,
Thanks for that info -well umm, yes i installed the correct drivers.
I use just the AU plugins or the basic logic ones on the channel strip
but even when i was going in dry there was still a delay.
I had experimented with the buffer size, as mentioned, but not gone down that low cus
last time i tried that i had other strange things happen!
But i will try again.
Sample rate was at zero, btw. Always says zero.
But today, when i just opened logic, the sample rate had changed. Strange. I need to understand this side of things so i'm gonna read up.
Also, if plugins are involved, i installed some novation bass station and some freeware TAL bass synth
stuff recently but don't have them up when i'm recording.
Maybe they sit there quietly and interfere just by their facial expressions or sumthing!!
I booted Mr MBP just now and i pulled out the USB and he's shining me a big ole red optical light
out of his output jack!!
In SysPrefs it has only optical digital as an output option.
In the last few days as i was playing around trying to correct the latency issue i noticed that the output options had changed to the UA25 and the 'digital optical' options - rather than the UA25 and 'line out'.
I'm off to go and read up on how to get my line out back, and try this buffer thing again.
Thanks again

Video Latency Issue On The Mac Book Pro 2.4 With Leopard 10.5.5
Gear: Macbook Pro (early 2008 model) - 2.4gigs cpu 2gigs ram - all the latest updates... no other applications running during the test
Hi folks. Currently I am having a latency issue when trying to record directly into iMovie using the built-in microphone and iSight camera. Basically, the video seems 5 - 7 frames late to the audio. I found that a good way to demonstrate this issue was simply doing a few handclaps as a test.
This is a quick handclap test displaying some video latency during recording with the iSight camera in iMovie 08.
- Just download this link — and import it into iMovie 08 - Here is a link to a zip file that you can import into iMovie 08 - It's 2.5meg - .m4v export - Also it was recorded as standard format and audio midi setup app: audio was set to 44.1:
http://www.brainbeast.com/37/clap-1-large.zip
- Play from beginning. As soon as you hear a clap sound — pause with the space bar - then back up before the clap with the left arrows
- Then click the right arrow several times until you hear the beginning of the clap sound ( This is the audio: start frame)
- Now — you will notice the video still has an open hand. At this point click the right arrow, counting as you go several times until you see the hand close. This is the amount of frames that the video is late to the audio. For me it seems to be an average of about 5-7 frames late.
Unfortunately iMovie 06 nor QuickTime will not scrub audio as you go frame by frame with the arrow keys so you cannot test it there. If you have some other application such as final cut Pro, you could test it with that.
! IF YOU WOULD LIKE TO PERFORM THE TEST YOURSELF:
- Just record a new movie in iMovie 08 - using the built-in mic and i-Sight camera — and see if it is also slightly out of sync
Note: to be as fair as possible — I did a slow handclap ( in order to not challenge the frame rates) - also, in order to get the maximum volume I used an open palm ( clap on the palms with your fingers spread out as you can see I did.)
Please let me know if this latency appears to be the same for you as it does for me.
Q: Is it just my machine or does it happen to you too?
Q: Does anyone know a way around this latency issue?
Q: Does anyone know if Apple is aware of this latency issue?I am experiencing the same incredibly frustrating problem as well. When I record directly into iMovie
'08, the video lags the audio by a fraction of a second.
I have tried shutting down all other applications and having only iMovie up. Same problem.
I tried recording the video into QuickTime instead of iMovie and experienced the same problem. (Which makes me think it is perhaps a hardware or operating system issue.)
I tried the technique suggested here and on other sites of "double-dragging" the clip from the Events pane into a project (one normal drag and one Shift+Cmd drag) so that I had the audio and video as two separate tracks. After muting the audio on the video track, I then attempted to slide the audio over to sync it with the video, but even down at the 1/2 second zoom setting I didn't seem to have enough granularity to move the audio so that it was exactly in sync with the video. I was wishing I could use the arrow keys or something like that to move the audio just one frame at a time.
All I want to do is record a video directly into iMovie '08 - this would seem to be something trivial to do! -

Dell 24" Latency Issues & Features?
I have a Quad on the way, and I'm looking at LCD displays for it. I've been reading the postings about Dell's 24" LCD, which looks like a winner in most respects, but was wondering about the "latency issue" I've read about here and there regarding LCD use for Photoshop still work vs. Final Cut video work. Does anyone know anything about this "issue?" Or if it is an "issue?" So far, the Dell spanks the Apple 23" in most aspects, especially price.
Are all of you Dell 24" owners happy with your purchase?
Can an Eye-One calibrator calibrate this Dell?
Are there any connection issues with the Dell for a Quad/Geo6600 OEM card?
Thanks!!I know I can still read this forum post at 90° off center...there's some brightness change around 45° off center, and ever-so-slight contrast shift at around 70° off center, but colors on my desktop seem to be 'still there'. I can litterally put my head on the 'side' of the display, so 1 eye is looking almost at the back of the display and the other at the front, and I can still define objects, colors and shapes, and read the 12-point text on this page. I just gets out of focus real easy since it's almost 2 feet 'distance' for my eyes to re-focus between the 'left' and 'right' of the screen :-D
The only complaint I do have of this monitor is that it's a 'bit' TOO bright, even set to the lowest brightness in the display's calibration. Although as LCDs get dimmer with age, I think it will work out in the long run...
(I just bought it last week). -
I just submitted a Customer Service request.
I see this has been an issue with other MSI P45 MB's. This system is purpose-built for recording, the spikes negatively affect my ability to record at low buffer settings. Otherwise, everything is perfect-very nice MB. Here's hoping they have a custom BIOS to fix this.

Rack case. Presonus Firestudio 26x26 & MSR, Presonus Digimax FS, Lucid GENx6-96 Word Clock, and more...Quote from: Thirteen on 11-February-09, 17:44:24
Is this a beta or a public BIOS?
When did you submit the request? (nothing happened with mine for the P45 Neo3 latency issue yet)
I submitted my issue to customer service (http://ocss.msi.com.tw/) on 9FEB. I received a reply 10FEB. The BIOS file has been on their ftp site since 23DEC08. It is not the public BIOS (1.6) available for download on MSI web site.
There is a BIOS I believe is for for your board with the same file name type as the one I used on the ftp site. Mine was A7513ICI.101. There is an A7514ICI.101 here: ftp://ftp.msi.com.tw/BIOS/7514/. Up to you if you want to chance it.
DL USBoot.rar from here: ftp://ftp.msi.com.tw/Tools/ follow directions to make bootable USB flash drive. I DL AFUWIN from here: http://www.ami.com/support/bios.cfm and found the newest version of AFUDOS.exe in one of the folders and put that on my bootable USB stick. The version MSI provided would not work for me. Change boot order to USB 2.0 first. Once booted on USB stick syntax I used was: afudos /i(BIOS filename) -no parenthesis when entering in DOS - at first it gave me an error but then it quickly proceeded to execute. I'd back up your current BIOS just in case.
Good luck. -

AGot that.. Thx.
But... How do I feed any of Logic's channel strip settings into my headphones while direct-monitoring off the Maestro Mixer ?
Trust me, it really helps to bring out a great performance from a singer if they hear the vocals that are being tracked with a few effects like reverb n' echo in their headphones WHILE they sing/track the vocals.
But what we want recorded is a dry signal, without any of the effects the singer is hearing on his/her headphones while they sing.
Now when I was working exclusively on Garageband, I could do this pretty easy. There weren't any latency issues too till my hard-drive bloated and OSX got sluggish.
Since a clean install and the move to Logic, it's been a mess really. I can't seem to get my way round this yet.
I always have Maestro open btw... In the mixer, the 'From Software' and 'To Hardware' faders are set to 0dB each. And Input 1, where my mic goes, is at 0dB too.
Where do we go now ? -
Help needed on Fixing replication latency issues
Hi Team,
Good day!!!
I am new to replication setup and I am working on the issues with replication latency.
Can you please provide us your experience and expertise on fixing and troubleshooting replication issues.
Below are some queries on that,
1) How to check the replication errors?
2) how to find out the replication latency?
3) What are the steps to fix the replication latency?
4) how to teoubleshoot the issues coming on replication latency?
Awaiting your valuable response and replies.
Thanks in advance,
Sarvan.NHi Sarvan,
Firstly, usually, we check replication errors via the Replication Monitor or by viewing replication agent job history. Besides the two methods, we can also check replication errors from the SQL Server error log and so on. For more details,
please review this
article.
Secondly, based on my research, the latency issues always occur in Transactional Replication. We can check that if there are latency issues by using Replication Monitor as well as Transact-SQL commands. Below is an example that posts a tracer token
record and uses the returned ID of the posted tracer token to view latency information. Refer to :
Measure Latency and Validate Connections for Transactional Replication.
DECLARE @publication AS sysname;
DECLARE @tokenID AS int;
SET @publication = N'AdvWorksProductTran';
USE [AdventureWorks2012]
-- Insert a new tracer token in the publication database.
EXEC sys.sp_posttracertoken
@publication = @publication,
@tracer_token_id = @tokenID OUTPUT;
SELECT 'The ID of the new tracer token is ''' +
CONVERT(varchar,@tokenID) + '''.'
GO
-- Wait 10 seconds for the token to make it to the Subscriber.
WAITFOR DELAY '00:00:10';
GO
-- Get latency information for the last inserted token.
DECLARE @publication AS sysname;
DECLARE @tokenID AS int;
SET @publication = N'AdvWorksProductTran';
CREATE TABLE #tokens (tracer_id int, publisher_commit datetime)
-- Return tracer token information to a temp table.
INSERT #tokens (tracer_id, publisher_commit)
EXEC sys.sp_helptracertokens @publication = @publication;
SET @tokenID = (SELECT TOP 1 tracer_id FROM #tokens
ORDER BY publisher_commit DESC)
DROP TABLE #tokens
-- Get history for the tracer token.
EXEC sys.sp_helptracertokenhistory
@publication = @publication,
@tracer_id = @tokenID;
GO
Thirdly, transactional replication latency issues could be caused by many factors, such as network traffic or bandwidth constraints, transactional load on the publisher, system resources, blocking/locking issues and so on. I recommend you troubleshoot latency
issues referring to the following blog.

DPC Latency issue, need to update BIOS?
I'm into recording music and latency is of great importance. I did a DPC latency check and noticed I was getting some major peaks, constantly. I tried everything, removing sound card, disabling drivers, etc, etc and nothing works. Then I did a google search and found this: https://forum-en.msi.com/index.php?topic=125206.0
I have...
Model name: 7519 v1.0
M/B ERP Version: 06
I have NEVER flashed BIOS before and have no idea how to do it. I don't even have a floppy drive. I really need to fix this latency issue though, otherwise I will have to buy a new computer :(
Can someone help me? I sent en inquiry to the support, but did not get a reply.
Thank you.Quote from: Jack on 29-March-11, 00:00:44
What is the model name of your mainboard? There are many MS-7519 mainboards with different PCB and ERP numbers (your ERP number is incomplete, there must be three digits):
http://eu.msi.com/service/search/?kw=7519&type=product
The best way to approach this, is to check your current BIOS Version as displayed on the P.O.S.T. Status Screen:
Write down the full BIOS ID String as it appears in the red box in the example picture. When we know the BIOS Version, it is possible to check whether or not there is Latency Fix for your board out there or not.
Have a look here and make yourself familiar with our MSI HQ Forum USB Flashing Tool: >>Use the MSI HQ Forum USB flasher<<.
