File transfer very slow with a SSTP VPN

I have a serer in the office and I connect from my house through a SSTP VPN. In my home computer (client) I add a new network folder, this networkf folder is in the server, that has a shared folder. I can transfer files, but is very slow.
For example, to transfer a folder that contain about 20 files, and in total are 11MB, it takes about 3 minutes. The server has a upload bandwidth of 890kbps. With teamviewer VPN takes about 1minute with 55 seconds.
The problema with the SSTP is that the transfer speed is not stable, bteween 0-200kbps. The problema is that when has to transfer a file, always the same, the speed drop to 0bytes/s and in this state is about 1-15 seconds and continue the transfer. Why?
So the total time at the end it's much more than the time that I need if the connection was stable and used all the bandwith. How I say, teamviewer VPN takes about 1:55 inteado of the 3:00 of SSTP.
Thank so much.

Hi ComptonAlvaro,
Please check if we have other program is connecting the Internet when we use the SSTP.
Additionally, we could contact the ISP to check the stability of network.
Regarding the slow SSTP performance issue, we could refer to the following thread similar to this issue.
http://social.technet.microsoft.com/Forums/en-US/8e8e4220-af25-4627-bed2-47db8c04d318/sstp-and-slow-transfer?forum=winserverNIS
Please take the following steps to fix this issue:
1. Add new registry key and value “ TcpAckFrequency=1 ” for all NICs on VPN server, so that we can reduce ACK delay.
2. Disable Windows 2008 SNP feature, and restart VPN server
3. Disable TCP Checksum offloading on VPN server
Hope it will be helpful.
Best regards,

Time machine file transfer very slow during OSX 10.7 re-install

I am using a macbook pro, and was running 10.7. (not sure exact version, and cannot look now, but should have been up to date) I tried the free upgrade to Mavericks, but it failed and said I had a disk error. At this point I could not boot back to 10.7 so I booted with apple-R. I tried to do a repair from disk utility but that failed so I erased my hard drive. Then I proceeded with an install of 10.7, which proceeded fine. I got to a point where it asked about transferring files, (forget the exact wording) and I said to use my time machine backup (from right before I tried the upgrade - backup was 80GB) and I started that. It has been 16 hours and it still has not finished. The external hard drive (Lacie) clicks / whirs, and I see signs of very slow progress... (seems to be at about 80% now judging by the progress bar) but it can go hours without any noticeable change. The "time remaining" information is variable -- going up and down -- and is clearly not correct-- has said 1.5 to 2.5 hours for the last 12 hours
Any ideas? should I just wait a few more days   should I abort and restart the file transfer (if so, what is the best way to do this?)
I cannot provide details on the computer since it is still busily restoring (I hope), but it is roughly 3-4 years old, lots of free space on hard drive (>100GB),

Apple File Sharing very slow with Mountain Lion

I've noticed since upgrading to 10.8 the transfer speeds over a LAN via AFP (File Sharing) are VERY slow.. in some instances. Based on the behaviour i'm guessing it has something to do with the amount of items.
for instance:
A folder that contains approx 122mb worth of 1500 small files takes me about 50 seconds to transfer while a long audio recording with a greater filesize of 125mb takes only 11 seconds.
using SCP from the command line the same 122mb folder took only 19 seconds while the audio took 10 seconds.
after performing the same operations on a computer running 10.6 I can deduce that the problem is on the receiving end. Audio file transfer times were the same, however the same folder of items took only 27 seconds when it was transferred to a computer running 10.6 regardless of which OS the computer sending the file was running.
apparently handling a greater number of files increases transfer time for both methods but AFP is painfully slow with 10.8 on the receiving end.
any thoughts or suggestions?
I've read a couple threads about people having trouble with Time Machine running slowly.. i wonder if this is related.

Same problem here. I just upgraded from Lion to Mountain Lion. I only got 19 GB of space, but Time Machine wants 10 hours, whereas in OSX Lion a full backup would take just under an hour, and incremental updates were lightning fast.
I even sat it up to do it overnight, but on 8 hours it was only half way through only 10 GB. I can't live with that in the future.
Im trying to backup on a SD card which seems to work very good in Lion. Im on a 2012 Macbook Air using a SSD.
My bite of the apple has been somewhat sour. I tried reformatting the SD card, well knowing that I would lose old backups. But still the backup is extremely slow. Now I can't install Lion or Mountain Lion from scratch without having to wait 10 hours for TM backup or installing tons of applications and settings again. Bummer. I'm never going to early adobt a OSX upgrade again.

Wireless File Transfer VERY Slow

Might not be the right forum but does anyone have any idea how to set up the wireless connection to be very fast? I thought it was something to do the 54mbs?? Is it something I need to change on all the macs?

No b clients just one mac plugged directly into the
router via ethernet cord, and then my powerbook which
connects wirelessy... to copy a 20mb file it took
10mins...
Which router do you have?

Saving files is very slow!!!

Since I installed (updated) from CS5 to CS5.1, saving files is very slow. It takes like 4 minutes save a 2048 X 2048 png file which used to take seconds in CS5.
I am not sure what changed... I completely uninstalled all versions of Photoshop. Re-downloaded from the website. Deleted my user preferences and the problem remains.
Why is saving so slow all of a sudden?
Using Windows 7 - 64 bit

Hm, that's kind of alarming. Is it happening with all files or just PNG.
If every file does that, it could be a possible indication that your disk is going bad...
Click Start and type view events into the search box.
When View event logs comes up, click it.
Navigate down into Windows Logs > System and see if there are any Error events there that indicate problems with your disk.
If this isn't the problem, it's possible that Photoshop is having to wait for a disk to spin up to be able to access it. Do you see the problem occur when you save again right away? Are you using an external drive for either file storage or as a scratch disk in Photoshop?
Lastly, you may have a stored printer or drive connection to a location on your network that does not exist now (or is not responding) and that has to time out before completing the operation. Have you changed anything in your network lately?

TC VERY SLOW with backup

Suddenly, TC is VERY SLOW with backup. In fact, I went in and discovered that it had not completed a backup since July 19th. I started one last night and when I checked this morning (about 10 hours later) it was 70MB into a 2GB backup. An hour and a half later it was at 100MB and an hour after that it was at 125MB. At this rate, it's going to take a couple of days so I cancelled the backup (it then went into it's housekeeping routine of "cleaning up"). BTW, I had quit all applications before I started the backup and TC said I had 454GB of free space. I'm not running any AV software and I have OS 10.6.8 I'm on an Ethernet network to the TC (I also have Airport active - could that be an issue? It never was in the past)
Any ideas would be appreciated.

So...I may have panicked when I saw all of those empty folders in my Document folder...however, when stopping the backup to TC (the 'cleaning up' process of stopping took more than 2 hours), my folder contents showed up. I guess that process takes the file index pointers offline or something so I couldn't see file contents during the process. I then did a permissions repair and a verify on my hard drive.
But the bad news is that my Time Machine is still showing EMPTY! I currently running disc utility 'verify' on my TM backup volume (it says the projected time to complete is 3 days!!!) The disc utility says that there are 4,000,000 files in the backup volume - I just can't see them. When I ran Time Machine, it only has 'today' - no prior backups - even though Time Machine Preferences reports that the oldest backup is August 1, 2010 (one year ago) and that the last backup was July 19, 2011. They are not there.
I've seen some other posts like this, so I don't think I'm alone with this problem.
The good news is that all of my folders and files on my computer appear to be intact. The bad news is that previous Time Machine backups are not there (or they can't be seen - even though the 1TB backup volume is in fact half full).

My macbook pro is running very slow with some strange mouse and window movements. The trackpad is very unresponsive and when responding the cursor moves on its own and/or very erratically. When on safari the window suddenly zooms in or highlights words.

I fee like I may have a virus or my laptop is perhaps being accessed remotely. All of the sharing options are unchecked.
HELP PLEASE
Very worried!!

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
     after the chime press and hold down the OPTION key until the boot manager screen appears.
     Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
     Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

Imac is very slow with downloading mail

My imac is the ast weeks very slow with downlaoading mail.
I am using mail 5.3 from apple
Nothing has recently been chanched in my internet setting or internet speed
Anybody an idea what can be wrong?

Hi, I worked out what you recommended, but I do not see any difference at speed.
Mail starts normal, though that is also somewhat slow,
Before it has finished downloading mail (even is there os no mail!) it takes sometimes 2 minutes!
Also there was no"boing"when starting up, with following your procedure, is it normal?

AE CS6 very slow with footage

Hi guys,
I am using AE Effects CS6 (11.0.4.2) on a new Macbook Pro with these specs:
2.8 GHz Intel Core i5
16 GB MHz DDR3
Intel Iris 1536 MB
The problem I am having is that when imported footage is visible as footage or a layer, AE becomes very slow with every click of the mouse on either the timeline or the footage in the viewer itself causing the color wheel to appear, often for 30 seconds at a time. Strangely, dealing with the composition has no issues.
Any ideas guys?
Thanks in advance

Try transcoding the footage to a production codec and see if that makes a difference.
Like, use the Adobe Media Encoder to make them something like QuickTime with the PhotoJPEG codec.
See if that helps with the performance.

Reading pdf files is very slow on my nokia 5800 mobile phone

Reading pdf files is very slow on my nokia 5800 mobile phone. I have Adobe Reader LE 2.5 and when i open any pdf file, it runs very slow and the scrolling is very slow in spite of opening pdf files which contain text only and in black color. I have tried also wrap text option and the problem persists. Is there anyway to reduce the quality of the pdf displayed on my mobile?? and What i have to do to make it run smooth and fast to make reading on my mobile possible???
Thanks in advance

I had the same problem and I culd not find the solution. I think it is a nokia issue, as I read it in several webs

I want to get a new iPhone to replace this defective phone. I am gonna be crazzzzzzzyyyyyyyy with anger,!!!,!,,,! I takes2 hours to go to Regent street apple stores for three times!!!!!. It is a lot of transport fees !
PLz tell me why! How to deal with it !

Unless it's confirmed officially that your phone is defective, then you can ask for a replacement. Or you have to live with you. However you can trade it for a new one if you don't care the price drop.

Ftp.belnet.be mirror very slow with updates

The mirror that is closest to my location, ftp.belnet.be , seems to be very slow with updates for AL.
XFCE4 was updated to 4.2.3 around nov 10 on archlinux.org.
11 days later xfce4 4.2.2 is still on belnet , and not replaced by the new version.
Since it's also a fast and reliable server, i don't mind waiting a few days, but more than a week is TOO long.
What's the use of a bleeding edge distribution when you can't get updates that have been available for more than a week ?
For now, i have fallen back on archlinux.org , but will look for another european server.

In contrast with the name, that server doesn't seem to have ANY arch packages anymore.
