Skype Desktop - very slow transfer speeds

Hi. Ever since 6.x was released, it became almost impossible to send files. What changed, and what can I do to fix this issue?
Please do not redirect me to that same "catch-all" thread for this issue. I am well aware that others have had this problem. Yes, I have the "Send anon usage/performance info" setting enabled.
I am getting speeds ~1-3KB/sec for every transfer, no matter the person or group
Info:
Windows 8.1 x64
Skype Desktop v7.4.0.102
Core2Quad 2.8ghz / 8GB RAM / Geforce 550 GTX Ti
75/75Mbit ISP connection
As you can see, I have MORE than enough resources to send files at my highest connection speeds (10.1MB/sec). I have tried setting static ports for skype and allowing them through my router, tried different combinations of Skype connection settings, turning off my OS firewall, and even tried setting my machine in the DMZ. Nothing has increased Skype's ability to send files quickly. So, what is going on?
EDIT :: Just uploaded my DXDiag results in ZIP archive

Did you get a reply to this? I have been having similar issues with extremely slow file transfers. It seems independant of who I am sending the files to. Also I notice when I am sending a file not only does it go slowly it slows downmy whole internet (so it seems to be using a whole lot more bandwidth than just the data of the actual file I am sending). I have the latest skype and IE and never had issues previously.

Very slow transfer speeds with external hard drives through Firewire and US

Hi All,
My external drives transfer very slowly on my MacPro. I've been searching for answers and have turned up very little. Apple support suggested I post my issue here. Just to make a note, I measured my disk speeds with both AJA System Test and copying files between drives and reading the Disk Activity in Activity Monitor.
I have 3 external drives, all MyBook Premium or Professional, 1x 500GB, 1x 1TB and 2x 1TB in RAID 0. I had them on Firewire 400 and the RAID 0 2TB one on Firewire 800. My transfers on FW were all around 24MB/sec on all drives (much less than what I should be getting with FW400). I then read somewhere that the FW bus on the MacPro uses the slowest speed connected for all FW connections. So I unplugged everything but the FW800 Raid 0 drive and my transfer rate jumped to 40-60MB/sec. This is much better, but still about half or so of what I expect it should be producing from an external RAID 0 setup.
To keep my FW800 backup drive faster, I've plugged the other two into USB2.0. The transfer speeds on both drives are now hideous, around 10-15MB/sec. This is so slow, but I'm not sure what to try to fix my speeds.
The HD's in the external drives are all 7200rpm, and all should be transferring at a higher rate. Do you have any suggestions or ideas? Ideally I'd like to get everything transferring at rates they should be transferring at, but I'll settle with my current FW800 speed of 40-60MB/sec if I can get my other two drives transferring at a non-snail pace.
Is this a common issue? I can't believe I'm the only one plugging multiple external hard drives into their Mac Pro. I hope someone has a fix or solution for this. I'm all ears!
Thanks in advance.

Hi Kappy, thanks for the information.
So I rejigged my setup a tad. My RAID 0 is still FW800, the second drive is back on FW400 on the back port, and the third is USB 2.0 on the back as well.
It's interesting to note that I saw the FW800 taking a bandwidth hit if the FW400 drives was being read/written to. For example, if I was averaging 50-60MB/sec on the FW800 drives and copy something large to the FW400 drive, each drive averages out to about 30/MB second, roughly half the FW800 speed I was getting. The USB while the slowest didn't cause any slowness on the FW drives.
Here are my Xbench results. These results are from each drive being benchmarked individually with no other drives being tested at the same time.

Very slow transfer speed between 2 computers in the same network

I recently bought a new laptop (Lenove G510) with win 8.1 pre-installed.
When i download files of the internet, my speed is ok, for wireless, but when tranfering files between computers (The other computer is a win 7), the transfer speed is really slow (2-4 MB/s). The transfers takes forever, and are relly unstable. It bounces from 1 - 4 Mb/s all the time and will not stabilize.
The same applys when streaming to other devices (Media Center). The video being streamd will just go frame by frame, and it is no fun watching...
Why is my transfer speed in local networsk so slow?? How can i fix this?
I use AVG Anitvirus, and I have tried disabeling it before transer, whitout results...
I have also updated BIOS, Chipset and the driver for the wireless network card...
I can also mention that when I turn my computer on, the internet connection is lost to all other devices... I then need to reset the router, and then the connection is fine again. This was never a problem before I got Windows 8.1, and is not a problem while the computer is turned of.
In advanced, thansk for any replys/tips
Regars, Morten

Just to be sure it's set up properly, please work through the steps on this page:

HARD DISK replacement because of very slow transfer speed

i own HP G6-2005AX, i got it with TOSHIBA HARD DISK,Model - (MK5076GSX) my problem is that while transferrig data from C drive to any other drive, the speed is very vety low (6-9 MB/S).is there a problem in my laptop? i have bought it on 22 0ct 2012, i still have 1 year accidental warranty, can i get it replaced?,can i get hard disk of some other company?(same capacity)
i can post scrrenshot if required.
thanks

Hi,
If you weren't using USB, then were you were transferring data between partitions or to a multimedia flash drive?
Have you mistaken a partition (primary or logical partition) for a physical drive?
Your notebook has four partitions, unless you have changed the original factory partitioning scheme. C: D: System and HP_Tools.
The following image shows how my loaner Envy17-3002ea is organized. It is a bit different as it has two physical 750 GB hard disks. Everything as showng inside Disk 0 is a partition.
What software did you use to determine the transfer speed?
Which CPU is installed in your notebook?

Very slow transfer speeds with Airport Extreme and MacBook

I have been using a new Airport Extreme without problem at my home for the past six weeks. The speed and range was excellent with both my MacBook Pro and the MacBook which I purchased a few weeks ago. I came out to Greece with both laptops and a new AP Extreme box for my home network here. After set up I noticed that internet access was lethargic on the MacBook and file transfer between the two computers was extremely slow. The problem seems to be with the new MacBook (although it was working well in London). I've done some speed tests and the internet download speed is only 48 kpbs! I also notice that the range is very poor--in the room next to the router I am down to five bars. If I connect to the AP Extreme with cable I get the full 1Mbps I would normally expect here in Athens (ADSL nominal 2Mbps). The MacBook Pro has no problems with wireless access speeds or range, so I am assuming this has to be a problem with the AP extreme card in the MacBook. Is there anything I have overlooked? Perhaps something to do with setting up the new AP Extreme here in Athens?

By process of elimination I realised that the only cause of the sudden slowness must be software that I had installed recently. The only software I had added was a wifi utility to detect available networks--open or protected. Unlikely as it sounds, quitting the utility (which I had set to load on startup) made a dramatic improvement in performance.

Very slow download speeds with ATT U-Verse

Hello,
Experiencing very slow download speeds with Macbook Pro 2011, on Lion, and ATT UVerse Max, which should allow for an avg. 11-12 MBPS speed. Instead, I get a fluctuating 60-370 kbps speed. I am not experiencing this problem on my Windows machines (Laptop running Windows 7 and Desktop on XP), it is only affecting the Macbook pro. I wonder if this issue is a known problem with ATT U-Verse and Macs, I spent hours yesterday with their support online and they couldn't help me, stating that from their side all settings were OK; the first representative from ATT re-booted the router remotely and that seemed to work for about 10 minutes, and then it went back to a crawling speed...
Any suggestions welcome!
Thanks

Do you have QOS enabled in your router? Did you try plugging the win7 laptop directly and check the speed?

Very slow broadband speeds

Hello
My first post, and I'm hoping that someone will be able to help me with this.
For a few days now, I've been experiencing very slow broadband speeds (100kbps or less), in contrast to the 1.5 - 2Mbps that I would usually expect to get. I've been on hold to BT technical support for some time, and have got through twice, on both occasions being told that this is a widespread issue and to wait until the next day. However, I'm not seeing any improvement. I'm aware of the problems in Edinburgh and the North of England,but I'm in East Anglia.

Deej.

Once a line is stable and working well, it's best left running 24/7
Interventions like resets, replacing accelerators, unplugging the router etc. will cause line "flapping"
And the dslam sees this as instability, and in turn the BRAS lowers the IP profile ....
This is done to achieve stability, and decrease throughput purposefully, all done automatically.
What you have to do, is cure any line noise, plug directly into the master or test socket behind the NTE
faceplate, leave it connected and wait for the throughput to increase.
Very often a rock bottom IP may need a kick to get it out of the doldrums.
Eventually the noise margin will decrease, sync will increase, and IP profile go up.
Depending on how long the line has suffered impulse noise, will determine the time for SNR to come down.
Regardless of which type of phone you used to test quietline ... hum or crackle is a no-no.
It may be the cause of the problems. It could be REIN on the network portion of the connection or dslam
crosstalk, either way it needs to be reported as line noise before you can count it out of the equation.

External firewire hard drive reverts to slower transfer speeds

This is the strangest hardware problem I've come across. I'm running a unibody mbp (June 2009) with an external WD 2.0TB Caviar Green drive mounted in a firewire 800 enclosure made by icydock.
Lately, I've noticed that after an unknown amount of uptime, the speed of file transfers to the WD external drive slows down dramatically. I figured this out by watching my time machine transfers take a bit longer after awhile, and I verified this using aja system test and speedutilities.
When I boot my mbp in the morning, file transfers and time machine backups to the external WD transfer at a rate of about 67-75MB/s. This is the speed the drive should always be working at since it's connected via firewire 800. Aja speedtest verifies the speed is as it should be as well.
Then, after a couple hours of using my mbp, or even later in the day, I'll transfer a file to the external WD or run a time machine backup and find that the transfer will only run at a max of 29-35MB/s. This is exactly half the speed the transfer should be going at. Subsequent transfers stay at this slower rate no matter what I do.
However, I've been able to fix this problem by unmounting and remounting the external WD or restarting my mbp. After doing either of these actions, the WD external goes back to contant transfers at 75-80Mbs. So something is happening where the longer the mbp is running, or after some sort of disk activity, the external WD reverts to a slower transfer speed (closer to FW400). I can't isolate whether it's an issue on the mac os side or the hard drive or the hard drive enclosure because I can make the hard drive go back to optimal speed again merely by unmounting and remounting it. This works consistently until a few hours later when the drive begins to handle transfers at half speed again.
I run hourly time machine backups to the drive. The time machine backups can't be the culprit because the drive remains running at optimal speed after the backups (verified with aja system test and speed utilities)
Any possible ideas as to why the drive cuts down to half its optimal transfer rate after a bit of time? I can't figure out the cause of this, and the consistency of the drop leads me to think this is an issue with the power management on the drive since it reverts to full fw800 speed when I umount and remount the drive or restart my computer. Could this be an OSX issue where for some reason the system isn't negotiating the fastest speed?
Any help appreciated.

From the SoftRAID manual:
Fire hubs and disk drives. FireWire hubs are notorious for introducing errors and instability onto the bus.
Make sure that all of your consumer electronic devices (iSight, cameras, scanners) are connected to a separate FW bus. These devices are not built to the same standards as storage devices and known for introducing errors onto a FW bus.
Cables. While most cables work fine with a single device, many cables will introduce errors when 2 or more disks are connected to the bus.

Help : very slow connection speed with AEBS and iMac

I connect to the internet using my newly purchased AEBS. I have a MacBook and an 24" iMac ( purchased in Nov 2007). My iMac showed very slow connecting speed of <1 MB/s download; with my MacBook placed just 1 foot from my iMac, the MacBook showed an amazing download speed of 20MB/s. If i connect the iMac to the AEBS using ethernet cable, it can get a very high speed.
So, where is the problem??
I am new to wireless, please help. I use iMac more than my MacBook at home.
Actually, i did not touch the any of the advance setting of the AEBS.

You know, I am experiencing the same problem. My wife's PC and iPhone are blazing fast, but my MacBook is accessing the internet at about dial-up speeds. Very frustrating and I haven't yet found the culprit.
Anyone???

Very Slow Download Speed

Hi,
I am experiencing very slow downloading speeds, when I am just normally downloading something in Safari, or downloading a torrent with upto 100 seeders.
The maximum download speed I have seen on my computer is 80kb/s, which is painfully slow for downloading the Adobe trials, when they reach about 1gb.
I have a router, connected to 2 computers, and speedtest.net has told me that my download speed is 1mb/s.
It seems like download speeds are being restricted to 80kb/s, so is there any way to 'unlock' full potential downloading speeds?
Any help much appreciated!
-Ollie

I think you're making the same mistake a lot of people make.
The maximum download speed I have seen on my computer is 80kb/s
Safari reports downloads in kiloBYTES per second, not kilobits, so that 80KB/s translates to about 640 kilobits per second.
downloading the Adobe trials, when they reach about 1gb
Really? 1 gigabit per second? I assume that's a typo.
speedtest.net has told me that my download speed is 1mb/s
therefore your downloads are progressing at about 64% of maximum. That sounds about right - you won't get maximum throughput for every download - it will vary based on server location, network load and more.

Very slow upload speed via infinity 2 (business) u...

Very slow upload speed via infinity 2 (business) unlimited after phone line fix (street cabinet) ?
Had my line fixed today by engineer (no dial tone).
Download rate near normal but upload = 0.73Mbps!?
I reset modem and router after he left and appreciate my profile is probably in need of some TLC after a weeks line fault, but is this normal in this situation? I heard it can take some time to reprofile my line and before it was fixed it was even worse at 0.10Mbps
Just seems very low considered the line is now operational again.

48Hrs+ on from residential line reconnection my business infinity 2 broadband upload speed is now approaching normal speed levels.
What a 10 days that was all because some ass disturbed the cabling in the street cabinet!
Yes I'm aware I have business broadband and am talking about it in a residential based forum, but my actual phone line is still residential that it is supplied over and the business broadband product is much the same animal as that supplied to residential customers i.e. Infinity 2 Unlimited. Only the mail and option of static i.p. appear different - that is all.
Jeez.

I'm with Sky, and have had very slow broadband for a while now. Above are the statistics from the test socket. Sky seem to think there is a problem with the line. I've now plugged the router into the main socket.
Any help would be appreciated.
**EDIT** My phone line is with BT, my broadband is with Sky. The problem Sky says is with the phone line it seems.

Hi Joe,
Try sticking your telephone number into this line tester page and let us know if it finds a fault. If it comes back clear, you'll need to go back to Sky as there'll be no issues with your telephone line. If it comes back with a line fault, we can get it progressed towards a fix

E1200 router: very slow download speeds, ok uploady got

I recently set up a new E1200 router to replace my old one. We are having problems with very slow download speeds (often <0.10 Mbps) even while the upload speeds are OK (8-10 Mbps). Our previous download speed over wifi was 10-15 Mbps.
When I first set it up, the download speed was very poor on the initial computer. After fooling around, it was fine. I don't know what I did that made it speed up. However, my wife's computer has had very poor download speeds. After rebooting my computer, the download speed has also dropped bak to <0.10. I was able to stream Hulu on my Wii just fine an hour ago.
What could the problem be?

So we could have this isolated, check how much speed you’re getting straight to the modem so we’ll have some point of comparison that from your internet provider. If through the router, you have struggles with not getting an acceptable value for download speed especially if it only happens with the wireless connection, you can try these: change the wireless channel and the wireless security on the router. If on the router, you have the channel set to auto by default change it to (3,6,9,11), just have to play around with it. Moreover, for the wireless security, select WPA2 Personal. If that doesn’t make any difference, update the firmware of the router, reset and have it reconfigured.
