Download speeds very low =ftp tests

Hey ,, i ran into a issue here,
few servers are connected directly to 6509 to gig ports with a speeds of 1000 full on either side and they are having a slow download speeds of 11 Mbps
if i try to download an ftp from any of these servers ,,,download speeds are at 11Mbps.
in the same switch speed is good between two servers and rest of the servers operate at low sppeds.
If i try to involve another server connected to another switch,,, it is 28Mbps.
can any one help me out figure out the issue.
I am not able to figure out the issue
Thnx

ok. if L1 is clear, try tcpdump on server and client side. maybe there are some errors in tcp communication, or something like this.

Very low ftp upload speed

run a dmesg to check if your hard drive's UDMA access has been enabled. What your network settings? (i.e. hub/switch/router/NIC(s)) etc.....

Mac App Store download speed very slow...

I have been trying to download the App Store updates OS X Update 10.10.3 and OS X Yosemite Recovery Update to my iMac for the past several days. When opening the Mac App Store, I click on updates and they appear. However, when I select 'download' my download speed slows to the point of less than 1 MB per minute.
I seem to remember this happening when Yosemite was first released, but after a few days, I had no problem downloading Yosemite from the App Store.
This only occurs when trying to download from the Mac App Store. When I download iOS App updates to iTunes I do not have the same problem so it seems to be only affecting the Mac App Store.
My internet speed is fine. I can download fine from other websites, just not the Mac App Store.
After searching online, I found one solution that looked promising:
Finder->Applications->Utilities->Keychain Access->Preferences->Certificates->Certificate Revocation List- Changed from Best attempt to OFF.
Unfortunately for me this had no effect so I changed the setting back.
I then looked for a way I could download the files from outside the Mac App Store & found this:
Apple - Support - Downloads
When downloading from Apple Support downloads page, my downloads were very fast. The Yosemite 2 GB Combo update took about 15 minutes, a far cry from the App Store which would have taken hours.
Is there some setting I need to change to increase the download speed from the Mac App Store or is it just overloaded servers? Why then can I download the files from the support page and not run into the same slow speeds? Updating iTunes was also giving me very slow download speeds, so again, I went to the Apple Support Downloads & clicked the link to download the latest version of iTunes. The file downloaded in about a minute.
Any suggestions would be appreciated.
Thanks!

Apple servers are overloaded. Instead of using App Store, use safari to download the updates manually from apple websites.
Here's a link for OS X 10.10.2 Combo Update.
OS X Yosemite 10.10.2 Combo Update
I had the same issue and downloaded manually from this link. It took me about 30-40 minutes. I'm using a 5mb connection. Your 40mb connection should be faster.
As for the iOS updates, you will have to download them from your iOS devices, because there are no standalone updates for iOS. Alternatively after you update your Mac, use iTunes to download iOS updates by connecting your iOS devices with your Mac. That should be faster than downloading through your iOS devices.

Upload Speed very low

I got bt inifnity about 2 weeks ago but while the download speed is working fine the upload speed is basically 0 and cant upload anything even a small file from a game. So any help would be great before i phone bt.

We were unable to identify any performance problem with your service at this time.
It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly.
If you continue to encounter a problem with a specific server, please contact the administrator of that server in the first instance.
Please visit the FAQ if you are unable to understand the test results.

Try to rule out the HomeHub.
First, power it off and on again (NOT the white modem) and see if that helps.
Then try a direct connection from the computer to the modem: a bit of a faffle I am afraid.
- connect from the modem LAN1 (that is usually connected to the HomeHub/router), to the standard ethernet port on the PC/Mac (that is also usually connected to the router.) So the HomeHub is out of the picture.
- Make a pppoe connection. On a PC it will be something like
- 'network and Sharing Centre',
- 'Set up a new connection',
- 'Connect to the Internet, set up a broadband or dial-up connection'
- 'Broadband PPPoE'
- Then enter username '[email protected]' and password 'bt'.
Detail may vary a little between different version of windows, and of course even more different on Mac or Linux.
Repeat your speed tests and see how they go.
That will help check out if the HomeHub is the problem.

Also do a test with firewall and antivirus turned (temporarily) off.
They can cause off speed problems.

Apple TV 2 Download Speeds Very Slow

I am using an Airport Extreme with ATV2. My ethernet connected download speeds are very fast yet my apple tv (and my other IOS devices - ipads) struggles to download movies from itunes. Most recently it showed over 2 hours to download a rented movie from itunes.
All equipment is updated with the latest software.
Any ideas about how I can see what the download speed is on my Apple TV?
Any thoughts on how I might be able to fix the problem wiht my apple TV

Welcome to the Apple Community.
The first thing to check would be your internet download speed, you can do this at www.speedtest.net.
1080p HD movies require a recommended speed of 8 Mbps, 720p HD movies require a recommended speed of 6 Mbps, while SD movies require a recommended speed of 2.5 Mbps.

Download speeds very slow

I've seen many other threads on slow download speeds, however most of those were last summer/fall after people upgraded to Lion. I bought a new iMac with Lion preinstalled (last summer) and have not had issues with download speeds until that last month or two. I believe the issue started with the Feb 1, 2012 system upgrade to 10.7.3. The iMac started to intermittently drop the wifi network. At this point the download speeds were also significantly slower. There was a patch that more or less fixed the dropping issue, however the download speeds are still awful. It still occasionally drops the wifi network, but not as often as before.
I've tried a few things to troubleshoot.
1) I have a Macbook Pro with Snow Leopard and I'm able to download a 2GB file in about 25 minutes wirelessly. On the iMac it estimates over 2 hours but takes longer.
2) I checked the firmware on my Qwest Actiontec modem, and it's up to date.
3) when I plug my iMac directly into the modem with an ethernet cable it's able to download the 2GB file in about 25 minutes.
Thoughts on how to resolve this?
Thanks!

Hi
I am in exactly the same situation with the ASA 5510 running security plus license, version 8.0(5) 512 MB RAM
going to try to upgrade the IOS tonight and upgrade the RAM to 1GB to take it up to version 9 will let you know if it helps,
cureently download speeds are very bad aroudn 14MB where as uploads are around 96 MB

Strange problem with broadband. Speed very low.

Hi all,
From last Friday I encountered really big problems with my broadband as the speed go dramatically down. I don't know what may be the reason, I'm using HomeHub and between it and computers in my household everything is fine. I haven't heard about any fixes round Aberdeen so have completely no clue what is going on.
Do you have any clue what can cause the problem, for more than 3 years everything was just great. Maybe my HomeHub is old and faulty, it is the 1st gen, white one.

Update.
First, do you always get reply from MODS? Today my connection dropped and after a while it was on again, I found my SN Margin reset to 6.5 and better bandwith 1205 / 19832 but the speed didn't improve at all. It is 24h since I've sent notice to MODS and I will wait another 24h before contacting them again. What really worries me is FEC Errors field in my ADSL Line details. Last time after 4 days it was 245'000, now after 6 hours I have more than 750'000. Is that normal after connection drop? I've checked speed using this speedcheck provided and my profile is still the same, 16000kbs
UPDATE:: 40 minutes past, 35 MB more dowloaded and 100'000 FEC Errors more :/

My internet download speeds very slow

Dear Sir or Madam:I changed my cable service plan on 3/6/2015. Internet download speeds should be 25Mbp/s. Unfortunately, Comcast never support this kind of download speeds rate to my service requested rate. I checked the download speeds rate ever day, without 3/6/2015—3/9/2015, the download speeds rate reached 5Mbp/s, otherwise, until now, there are no any one day , the download speeds rate up to 2mbp/s, sometime even download speeds is zero 0 bp/s ; most time download speeds only around 100Kbp/s. or under 100kbps.I bought new Gateway model Motorola SBG6580 that is working perfectly. I checked cable connection is good.I paid for 25mbps download speeds rate. Comcast given me only at 100kbps download speeds rate. This is too much overly fault service, I can’t accepted.I hope Comcast fix the problem immediately. Thank you.

I am getting 1.2MB currently.
Sometimes I get lot more.
I understand technically why you
think Apple resolution would put
more demands on bandwidth.
1080P for my TV.
As I said this worked for other
apple movie rentals in past.
I have been using same Dsl
service for many years.
I know you are going to say that
my bandwidth is too slow.
Which Dsl customer gets 6MB?
How much do they pay each month
to get that kind of bandwidth.
I pay $80/mo and get 5 IPs which
I need.

Re: Strange problem with broadband. Speed very low...

What is going on with my BT Broadband speed...?

I moved you post to start a new thread as previous one was marked as solved by originator
welcome to the BT community forum where customers help customers and only BT employees are the forum mods
in order for the forum members to help please can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester (MAC users may have problems). when first test completes then run diagnostic test and post the results .
are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
Someone may then be able to offer help/assistance/suggestions to your problem

Estimated FTTC speed very low

Hi
I am currently waiting for our newly installed cabinet to be enabled for infinity. We are 300m from cabinet and cable path is straight down road. BT wholesale checker give an estimate of 3.3mb for fttc speed. I am thinking this cannot possibly be correct? We currently get about 2mb adsl and we are about 5km from exchange.
Checker on BT retail site does not give estimated speed. Is this because wholesale estimate is so low?
Thanks
Solved!
Go to Solution.

take the estiamtor wiht a pinch of salt untill your fttc is actualy enabled it wont give accurate info, if its already enabled and the information propagated to the line estimator then it could be down to a lot of different things, including but not limited ot the type of metal used in the line, known High Resistence joints etc etc. if the retail checker isnt giving and estimate then chances are its still awaiting activation and is just giving out the adslmax rateing for your area.

Wifi download speed very slow comparing to ethernet

Hello!
I have very strange problem with internet connection in my iMac.
I have a linksys router and 6Mbps broadband (slow or not, it's Poland ).
I try to download the same file via wifi or cable (connected to linksys).
Transfer on cable: 600-800kBps, transfer on wifi 50-100kBps.
Why is that?
It's very strange because ma macbook pro connected via wifi to linksys downloads the same file with transfer as well 600-800kBps.
On iMac there is Leopard 10.5.5. Linksys was restarted many times. iMac - 24" inch model 2.8GHz.
Does anybody know any solution?
Thanks in advance
Christopher

hello anybody?
please

Wifi speeds very low

I feel that BT are leading a misleading campaign on "The best wifi speeds" on TV. I have just moved over from Talktalk where my speeds were great and the wifi was quick. BT wifi speeds come no where near the speeds I was getting before. If I'm cabled my line speeds are ok at 73mb BUT, wifi goes down to 2.8 down & .6 up. I have split the channels to see if this works and still no good. Speaking to the help desk was a waist of time as they only want me to factory reset my hh5 that is only 4 weeks old. I have been working as an IT employee for the last 10 years and in my experience this causes more issues than it resolves.
Please, has anyone got the same issue with the wifi speeds on the HH5 as this is killing me. If you advertise FASTEST WIFI SPEEDS then deliver these speeds or I will look at my contract and leave.

You really need to use wireless-AC to get the best speeds.

Very low broadband speed

Hello
I rejoined BT three weeks ago having spent two years with Zen. I was with BT prior to that and had moved to Infinity with sppeds of about 26Mbps - not great but adequate.
Nothing changed when I moved to Zen. Obviously the cabling and exchange was the same and no upgrade or modernisation has been carried out. The speed therefore remained the same.
I have had problems though since I moved back to BT with the broadband dropping out regularly. After about 8 calls to India taking up hours of my time and two engineer visits the fault has apparently been rectified.
Quite what was wrong seemed to chamge on a daily basis from a "missing port" in the Excchange to "noise on the line" to a "problem with the cabling on the telegraph pole".
The issue though now is the speed which has dropped to about 9Mbps. This seems bizarre if nothing has changed at the excahnge or with the cabling and is certainly nothiong ner the promised 30Mbps?
Peter Atkinson

I reported the faulot and they are noiw saying that it's the Router.
Bizarrely though I came home at 2 today and the internet is back up and running.
It has got even slower though. It's now just over 8Mbps which is nowehere near what Infinity should be.
I've done the Wholsale Speed Test and it tells me:

To add, this has happened about once a month for the past 6 months or so, with speeds dropping to around 0.14Mbps, usually returning within a week. However since it happens quite often, and since the speeds are so low it means that for about one week a month (or more) the broadband is practically unusable. It's starting to get annoying because we aren't really getting what we're paying for!
What can we do to stop it from being set so low, or otherwise how can we get it reset sooner when it happens?
Thanks.
