Very high Latency and inconsistent download speeds

Hi all,
This is my first time on these forums and hopefully i can find some help for my horrible problem.
For the last 2-3 weeks my latency has consistently been 200+, i like to play online games alot and i cant with this latency. I have gone threw the whole drill of ringing BT and following there advice and i even had a BT engineer come out and he couldnt' find any problems. BT said they checked my line and couldn't find anything wrong, and the engineer didn't find any problems with the router (black).
I also have changed all of the wiring from the socket in the wall, which leads to the router, which leaders to a modem (i think its called that) that then connects me to the internet (Cable).
I am running out of patience as i spend alot of time on games such as Call of Duty and seeing my mates play it as i have 300+ ping is really annoying.
I Have noticed that the other computer my parents use also have the same high latency issue and they have tried it on cable and wireless with the same bad results. I have a program called xfire which shows my ping for all the servers on my list and there all 200+ but sometimes when i test my speeds on speedtest.net it shows me with 50 ping i believe this is due to the large spikes that i get, when im on call of duty it constantly jumps around 100, 150, 200 and sometimes even 50.
Any advice would be greatly appreciated.
Josh.
Also im not very good with computers so if anyone would like any figures or whatever just point me to the website and ill try and get them for you.

This looks ok but on xfire all the servers are at 300+ and when i go ingame there just as high.

Very high latency on my MBP 3,1 (mid 2007) with airport extreme card 0x168C

Hi
I wanted to let you know that i filled a bug report concerning a problem involving a MacBookPro3,1 and my airport extreme card (AirPort Extreme (0x168C, 0x87) Firmware Version 1.4.16.2)
If you've got any feedback, please feel free to share it with me.
Here's the bug report:
Hello
I'm experiencing very high latency on my MBP when connected using Wi-Fi in my living room and I believe this is a software bug.

Obviously, my Mac has very high latency where my PC works as expected.
I tried resetting the PRAM, but i didn't affect my results.
I tried updating Airport with the latest AirPort Client Update (http://support.apple.com/downloads/AirPortClient_Update_for_MacBook_and_MacBookPro), but my hardware wasn't eligible for that update (Mid 2007 MacBookPro).
I believe this isn't a hardware bug because i get acceptable ping results when next to my router or in other rooms of my flat.
Can you help me with that bug ?

Laurent

Why does my 10GB iSCSI setup seem see such high latency and how can I fix it?

I have a iscsi server setup with the following configuration
Dell R510
Perc H700 Raid controller
Windows Server 2012 R2
Intel Ethernet X520 10Gb
12 near line SAS drives
I have tried both Starwind and the built in Server 2012 iscsi software but see similar results. I am currently running the latest version of starwinds free
iscsi server.
I have connected it to a HP 8212 10Gb port which is also connected via 10Gb to our vmware servers. I have a dedicated vlan just for iscsi and have enabled
jumbo frames on the vlan.
I frequently see very high latency on my iscsi storage. So much so that it can timeout or hang vmware. I am not sure why. I can run IOmeter and
get some pretty decent results.
I am trying to determine why I see such high latency 100'ms. It doesn't seem to always happen, but several times throughout the day, vmware is complaining
about the latency of the datastore. I have a 10Gb iscsi connection between the servers. I wouldn't expect the disks to be able to max that out. The highest I could see when running IO meter was around 5Gb. I also don't see much load
at all on the iscsi server when I see the high latency. It seems network related, but I am not sure what settings I could check. The 10Gb connect should be plenty as I said and it is no where near maxing that out.
Any thoughts about any configuration changes I could make to my vmware enviroment, network card settings or any ideas on where I can troubleshoot this. I
am not able to find what is causing it. I reference this document and for changes to my iscsi settings

If both StarWind and MSFT target show the same numbers I can guess it's network configuration issue. Anything higher then 30 ms is a nightmare :( Did you properly tune your network stacks? What numbers (x-put and latency) you get for raw TCP numbers (NTtcp
and Iperf are handy to show)?
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

High latency and some PL, culprit seems to be a router within comcast

Hi: I reported this issue to Comcast support but I think I'll post it here too. I'm seeing high latency routing through the Comcast network to a variety of locations. In all endpoints I try, I see high latency except when I hit Comcast endpoints (which makes sense). Here's some output for you: WinMTR outputTraceroute output Note that in all cases, there is a significant slowdown somewhere between hop 9 and 11, always at a comcast router. This issue has been going on for a few hours. Anyone else seeing it?

Hi: (Not sure of the correct forum for this type of request so I'm reposting here after first posting over here) I posted a couple days ago with some issues that seem to have returned. Seeing high latency and occasional PL trying to get from my home to a variety of well-known endpoints. WinMTR output. Anyone else seeing the same? Comcast? This is starting to become a thing. Really annoying for those of us who rely on low latency connectivity when working from home!

High latency and poor speed tests lately

For the past 4-5 days, I've been working with various Verizon techs to resolve a high latency/slow Internet problem. Their ultimate solution was that they have no idea why it's doing this, and since I can reach a few websites at full speed and their line tests show I'm operating at full provisioning, it's not their problem. "We can't control traffic outside of our networks." Well, my results are also showing problems with the Verizon servers, so I would think they should be more concerned. Most websites, however, exhibit the problem. So I'm stuck, looking for a better answer than "go away." Maybe some of you are experiencing a similar problem with latency or sporadic speeds?
My provisioning is 20M/5M. I'm in the L.A. area. (In the traceroutes below, I masked Hop 2 for privacy.)
I've experienced this problem with 2 computers (1 desktop, 1 laptop), both using Ethernet ports; one test using wireless on the laptop. I've plugged the router directly into the ONT coax to eliminate my house wiring as the culprit. Westell 9100EM router.
A few websites seem okay, and speedtest.net results always show provisioning at full speed to the L.A. server, but the problem persists when using the non-L.A. server. With speakeasy.net, even the L.A. server exhibits the problem. The latency gets worse as the night goes on, sometimes over 1000ms for some traceroute hops. In the morning, it seems to be back to normal.
Thanks for any help....
Jeff

MisterJefferson, your problem looks to be with hop #3. That is a Verizon router just after the gateway router for you. This will need to be addressed by a Verizon Network technician. Your hops to your router and your hop to the gateway look fine. Verizon will need to reboot that second router or re-route your hops.
Chernabog, yours is more difficult, you dont have any obvious big issue. However you do have a moderate jump at hop number 8. this is off the verizon network and is out on the internet. on one of the ATT routers. Unlikely you are going to be able to do anything about this. And as it is off the Verizon network, there would be nothing verizon could do about it either. Usually though, if it is a router needing rebooting, it will generally self correct after a few days. Or you could be unlucky enough to be going through a system that is overloaded or just plain old. This can be frustraiting. I myself play a lot of online games and if the server is in Washington DC (I'm in California) one of the hops I have to go through is in kentucky with sprintlink and their routers constantly give me a 500ms ping and I havent been able to get it corrected in over 4 years. Something we sometimes have to live with when it is out of our control.

Updating to 10.6.7 Destroy's WiFi...(Very High Latency)

Updating to 10.6.7 seems to have made my wireless connections useless. everything was fine at 10.6.6... After upgrading to 10.6.7 I noticed terrible latency and lag while playing an online game. I looked at the server list for the game and did a refresh, all the servers normally listing 30-90ms were now in the hundreds. 500ms...800ms...etc... I thought it was nothing.. tried basic troubleshooting steps and determined that it wasn't just the online game. I started looking at the connection.
Ping reply's online were returning very bad response times.. so I said OK, I'll ping the gateway here and see.. cause that I know I should be getting <1ms or slightly higher... it was also extremely high.. 345...800...750 etc....
After some more basic troubleshooting I determined that it had to be the recently installed OS update... finding no solution to the issue online I decided to do a backup and reinstall OS X.
I did a fresh install of OS X the network was back to normal... I downloaded 10.6.7 combo update and installed it... wireless was destroyed again...it has to be the update....
I did yet another fresh install of OS X.. this time I installed the 10.6.6 combo update and all the other software updates except for 10.6.7... the wireless is perfectly fine!
I am left with the only conclusion that the 10.6.7 update destroy's wifi from a latency standpoint.. making it useless to me for the most part.. even for basic surfing... I had no issues with connecting to the wireless.. just that it was basically useless after 10.6.7. I am on an iMac 24" Intel Core2 Duo model.
Anyone else having this issue or know a solution? For now I will just be leaving 10.6.7 alone.

Welcome to Apple Discussions!
10.6.7 does nothing to my WiFi latency. My suggestion is to check if your router's firmware is up to date, and known to be 10.6.7 compatible. Just because it is 10.6 to 10.6.6 compatible does not mean it is 10.6.7 compatible. I have Apple's airport extreme base station with 802.11n. Check also if you are proxies, or have certain firewall ports enabled on the System Preferences -> Security & Sharing that might interfere with the router's own firewall ports. If you have stated DNS numbers in Apple menu -> System preferences -> Network, make sure they are also stated on the router's own setup page, or remove DNS numbers from both, as those can contribute to latency under certain conditions. I have an iMac 5,1 and my WiFi is doing great, even when running a VPN over VirtualBox with Windows XP. Double check the games in question have been tested with 10.6.7. They may have their own configuration issues. If the game uses Flash, make sure the version of Adobe Flash you are using has been tested with 10.6.7 by contacting Adobe.

Disconnects and Low download speed

We've had BT Broadband for over 10 years. We had a few problems at the start and had to stop using any of the telephone extensions when it was installed to get it working. Since then we've invested in numerous filters in an attempt to cure connection drops and bought an i-plate when the speed was suffering. Every so often, I get fed up with the time it takes me to deal with connection drops and ring the call centre. They are very sweet but all I get is a temporary solution at best and then it all goes poof again.
For the last year or two so resetting everything and waiting hasn't always been good enough to get a connection again. By accident, I found that if I made a telephone call, the broadband would come back again without me having to reset. This proved an expensive option until I discovered the quiet line test (for which I thank the helpful members here lol). My trouble is that its taking quite a long phone call to get the connection going now and it used to be worse when it rained but its now as bad if its sunny.
A possibly related issue is that our download speed has declined enormously over the years. I've not been able to watch the iPlayer since last year sometime and even YouTube pauses for ages every 10 seconds. i've had two Openreach engineers out recently and there is another fault report in progress atm. The trouble is, they don't seem to have made much difference so I'm despairing at the thought of another fruitless visit now.

I've been reading about resistance faults and wondered if our ancient telephone lines round here could be causing one? We're still on overhead lines I'm afraid and nearly 2km from the Batley exchange.

Just a quick update this morning. I emailed the mods yesterday so I have hopes.
On the 'normal route' side, the phone call from BT techies that the call centre booked me in for between 8am and 10am didn't happen and there was nothing updated on the online fault progress report since the call centre folk updated it yesterday. I rang the call centre again to tell them it hadn't happened so they are in the loop and its been escalated again. Had to go through their standard script etc but, hey, I'm reconciled...

Very High Pitched and Super Quiet beep/sound from DV6

They seem to make a new DV6 every year but This one is mine.
I've had this notebook since September and its awesome. But there is a very annoying issue I have always had with it. When I'm using it in a very quiet environment I can hear it emit a high pitched beep type sound every second. Its extremely quiet but its one of those sounds your brain suddenly notices and you can't stop hearing it - like when some old CRT monitors and tube TV's are left on. I usually only hear it when the PC is idle or doing very basic tasks like I'm doing now typing this. I thought for sure it was something else in my home for the first month until I was using the notebook someplace else and heard the same annoying sound. When I put my ear up to the notebook I can hear it better and that its somehow tied with the fan. I can hear the fan barely slow down by probably 5%, then that beep and the fan speeds up again. This happens continuously until I'm not idle. Anyone else notice this? My motherboard was replaced a month ago (It randomly died) but nothing changed.

Seems to be normal "CPU whine". Nothing can really be done about it. I've just been lucky with my notebooks in the past not having a whine. I set my networked storage a little closer to where I sit and it cancels out the CPU whine.

V04 and maximum download speed - how do BT get awa...

I have been a BT Vision customer for only 1 week and all seemed well at first.
I moved to where I now live on the 1st November and my Total Broadband service was implemented on that date (I have had Total Broadband for many years at my previous address).
Today I have the dreaded "V04" message and a line sped check reveals a download speed of only 1230 kbps (with an apparent line maximum of 2000 kbps). What the heck is that about? Is this the 21st century or not?
I live in the middle of a state of the art city development literally next door to the new MediaCity in Manchester (soon to be home to the BBC) so I would have expected line speeds here to be as high as you could have got ANYWHERE
In addition, how does BT justify selling a product they must KNOW (based on the maximum line speed figure the speed test has thrown up) will not be useable
If there really are BT people on this forum, I would love some answers and not from someone in a Mumbai call centre who, whilst trying their best, is really just going through the scripted responses
Another day like this and frankly, BT can shove their box up their nearest junction box!

I take it from your post that On Demand was working?
If so and your line speed has now dropped then you need to report a line fault.

I've extended my Time Capsule wifi via Airport Express and the download speed is still super slow

I get an average of 80Mbps download speed when close to the Time Capsule. When I got upstairs in the house the download speed drastically drops. So I decided to extend the wifi range using an Airport Express. See image below. I've placed the Express router upstairs in the house and when I stand close to the Express I get a very slow download speed. About 7Mbps. Even slower than when I hadn't "extended" the range. What's going on...?

I've placed the Express router upstairs in the house and when I stand close to the Express I get a very slow download speed. About 7Mbps. Even slower than when I hadn't "extended" the range. What's going on...?
Well, the first rule that you need to remember is that when you "extend" using wireless.....you will have a drop in the potential speed on the network. So, while you might have more "range" for the network, the network speed will drop. Nothing that you can really do about that other than connect the Time Capsule and AirPort Express using a wired Ethernet connection. There will be no speed loss over the Ethernet cable, so the Express should deliver approximately the same speed as the Time Capsule.
The next rule is that when a device "extends" using wireless, it can only extend the quality and speed of the signal that it receives. A speed "boost" will not appear.
Try locating the Express about half way between the Time Capsule and the area that needs more wireless coverage. Anything that you can do to minimize obstructions between the Time Capsule and Express and on to the other area will help.....but you will never get close to the performance of connecting the AirPorts using an wired Ethernet cable.
Unfortunately, Apple really doesn't tell you very clearly, if at all, about important things like the two rules above.

RDP traffic and upload/download speeds?

I would monitor your bandwidth at both edge devices.
RDP in my experience is typically more latency sensitive than bandwidth sensitive.
Most Internet providers will push you more bandwidth but that will not help the time it takes the data to get back and fourth.
If you are maxing you connection out in Houston than more bandwidth may be something to consider. Also depending on the cost of the Internet service upgrade.
You may also look into filtering unwanted traffic from the Houston office. Such as Youtube or recently I found a receptionist watching Hulu.

I'm having a difficult time understanding how upload/download speeds factor into RDP session speed. I have a company in Houston that hosts an RDS server that has a remote app that uses a local SQL server to get data from. We have a remote office in Dubai that accesses the RDS server to use this SQL app.
In Houston we have 20/20 fiber. In Dubai they have 100/28 cable. The Dubai office complains about speed. The Houston office is thinking of upgrading to 40/40 connection. Will that help Dubai's user experience?

Low bandwidth and slow download speeds

On a normal day, our router (a BT HomeHub 1.5) reports about 1700 kbps downstream bandwidth, and downloads at around 100-180 kBps from most websites. On Saturday, after it reset itself several times repeatedly, the downstream bandwidth dropped to about 400kbps, and download speeds dropped to 20-30 kBps. I did the usual of resetting the router (power off, wait 30 seconds, power on), with no effect.
After about an hour of these speeds with no change, I gave the BT hotline a call. We did the usual checks (plugged into the master socket, all phones in the house passing through filters, line attenuator/accelerator attached to the master socket) and then she did a line test and couldn't find any faults. I have since also done a quiet line test (17070, option 2) and couldn't hear any significant static.
I was advised to leave the router on for 24 hours without resetting it so the line could be reprofiled. The router managed to reset itself overnight for Sunday morning, but has now been on for over a day, with no change in connection quality. We've done reprofiling once or twice before, and generally it fixes itself in a few hours.
Today, I ran btspeedtester and checked the ADSL Line Details page of the router. You can see the results at the bottom.
So, is there anything I'm missing on checking (I find it highly unlikely that 'leaving it alone' for 3/5/10 days is going to do anything other than waste my time; see almost every other speed problem topic in the last few weeks to notice that there is a trend of problems not fixing themselves if you just wait ), or should I go ahead and send in a customer support request for the mods here?

Very high latency in fetching static files

Problem : Really high latency in fetching static files upon first request.
Environment : Weblogic V8.1 App Server and Web Server running using jdk1.4.2_13
Mem Setting: -Xmx2048M -XX:MaxPermSize=1024M
Situaton: Restart the weblogic server, fetch a static file using " wget hostname:port/script.js". Comes back in around 100 ms for us. Then from browser we request "http://hostname:portname/Logon.do". Then again we do " wget hostname:port/script.js" and now it comes back in 400 ms. The above times are in our TEST environment. In PROD it is really worse 1300ms for one file !!!
Tests:
Wrote a servlet to handle all static file (CSS,js,gif,jpeg etc) and all requests would go through this servlet. Did not solve the problem, latency is still high.
Wrote a test servlet to load about 1000 classes explicitly (Class.forName) and then fetched the static file with out accessing Logon.do from browser. Latency was high after loading classes. This lead to conclusion that it is number of classes we are loading which is causing the problem.
Ran application under JProfiler, Took a heap dump right after starting server. About 1300 classes loaded. Took a heap dump after fetching Logon.do. About 2100 classes loaded.
Question :
1) Isn't 1300 too high for just the server to start? (there are some classes loaded because of our references in ejb's)
2) We use prototype factory to instantiate classes. All the interface and implementation definitions are specified in config file and it seems to load all the classes. May be we can change this. But what confuses me is that the response time was okay when we had 1300 classes loaded how come it became so bad when there were 2100 classes ?
If any body is using these same set of technologies, what is the average number of classes loaded on initial start up?
I am running out of options to test?

There's no way from what you posted that you could draw a conclusion that you are infected.
I totally missed that tracert, but from a ping response time, it looks healthy.
The packet loss, could easily cause your problem.
Does it consistently loose packets there ? Cause I've pinged it from here and got no loss.
Also remember that in this case, ping is also the time it takes the blizzard servers to response to your network message, so it could be local to blizzard, and ping might not detect that.
Have you tried a netstat -p tcp -b command too see whats active on your PC ? That could point you towards something local.

SLOW inconsistent download speeds

OK here's my story.
Currently paying 25 download/25 upload on my internet. Past few days noticed some lag on my
internet activity, ran speed tests on different sites and most numbers were similar and that I was getting
around 1-5mb download/ around 20 upload. But when I check Verizon's speed tests. IM getting an
amazing 30mps/30mps which IM sure is not the case.
called verizon. they said they dont see any problems at their end. did the basic troubleshooting. and reached
to the point that a new router could be the solution. got a new router. got a new IP. plugged it in and still
NO changes to my connections. Is anyone else having this problem? I have given up on verizon support. and if i cant
get solutions here. i think Optimum online is my next option.
I am in new york btw.
