Ridiculously slow airport disc transfer speed

I just set up a new AirPort Extreme on my existing network, and the airport disk feature is unbearably slow. The finder locks up for nearly a minute just connecting to the disk, and then again when i open a folder. It took over a minute to copy a 60k file.
I'm using a MacBook Pro (2ghz Core Duo)
Wireless Card Type: AirPort Extreme (0x168C, 0x86)
Wireless Card Firmware Version: 1.1.8.5
Right now the APE is set up to extend an existing network but I initially set it up as a new network and had the same problem. Is this really the best transfer speed i can expect?

No.
Depending on which network settings you have, you should be able to move 150-400 Megabytes to an Airdisk in a minute.
You are probably seeing either a network problem, or disk errors causing the AEBS to retry.

Airport Disk Transfer Speeds - Straw Poll?

I know there has been a lot of coverage around the speed of the Airport Disk (USB drive hooked up to the AEBS) but I just wanted to take a straw poll of the speeds people are getting.
From limited testing I seem to be able to get transfer speeds (copying to the disk) of around 1-2 MByte / sec. eg copying a 32Mb folder of Word docs took about 20 seconds. Trying to do a complete backup of my iPhoto Library (10 Gb) was going to take hours (or days!).
This is a fraction of the speed of the USB drive connected directly. My Core2 iMac is connected to the AEBS in 802.11n 5Ghz mode in case anyone asks.
What real-world speeds is everyone else getting?

AJA Kona have a utility for testing disk speed. It's pretty good. Enable network volumes from preferences.

Slow VPN PPTP Transfer Speeds vs. Windows XP

I recently switched my father to a new unibody MacBook after years of Windows XP heartache. He uses a VPN (PPTP) connection to access files on the Windows 2003 server at work.
*On the Mac (10.5.5), the file transfer speed over VPN is so slow that it is unusable.* Leopard can connect to the SMB server easily enough but clicking on a volume shows nothing until, after a 2-3 minute wait, the file list finally populates. The old Windows XP machine loads the volumes far quicker and is noticeably faster.
We are using the same credentials and settings as on the old machine, but nothing we do will speed up the connection so that it is actually usable.
Any thoughts or suggestions? At this stage I am extremely disappointed in the Mac's ability to integrate with enterprise. I was so sure the transition would be seamless but Leopard is making basic tasks much more difficult. It's egg on my face!
Help would be much appreciated!
Thanks, jd.
P.S. My apologies if this has already been discussed. Searching didn't give me many relevant results...

Hi Joe,
College networks can have a lot of unusual security monitoring systems in place, so it's conceivable that they limit non-PC speed, but as you said, you've checked that.
There is a known issue with some Gigabit Ethernet capable Macintosh systems and some switches. This problem can be fixed by software configuration, so it's possible Windows automatically does it, but MacOS doesn't. Have a look at the instructions specified in this Apple article and see if it helps: http://docs.info.apple.com/article.html?artnum=303660

Airport Extreme's AirPort Disk Transfer Speed

I have an AirPort Extreme (802.11n) with a USB drive attached. I have noticed that when the same drive is connected to another computer on the network my transfer speeds increases by at least 2x. In all cases I am connecting to the drive from a MacBook Pro over wireless with the AirPort Extreme as the network hub.
Is this due to a technical limitation of AirPort Extreme/AirPort Disk?

Go to /Library/Preferences/System Configuration.
Move all the files from the System Configuration folder to the Trash.
See if that helps.
If not, launch AirPort Utility. Select the base station on the left then click Manual Setup. Select AirPort from the menu then select the Wireless tab.
Try a different channel then click Update.

Slow large file transfer speed with LaCie 1T firewire 800 drives

I am transferring two large files (201gb and 95gb) from one LaCie 1T firewire external drives to another one (using separate connections to a PCI Express firewire 800 card in my Quad G5. The transfer time is incredibly slow – over for hours for the 201gb file and over 2 hours for the 95gb file.
Does anyone have any ideas why this is so slow or what I might try to speed up the transfer rates?
Thank you.

Very slow Ethernet & WIFI transfer speeds - MC340X/A

Hi.
I recently purchased an Airport Extreme model no. MC340X/A being used as an isolated standalone network with 3 gigabit ethernet clients and a couple of n WIFI clients, and no other base station or Hub/Switch in the network.
One of the problems I have is that I'm experiencing very slow network transfers between both ethernet clients and wifi clients of any combination. The maximum transfer rate I can achieve between ethernet to ethernet, WIFI to WIFI, or WIFI to ethernet clients connected to the MC340X/A is 2.5 MBytes / second, on both 2.4 and 5gig bands using n capable WIFI cards and gigabit ethernet cards.
I have performed a hard reset of the device with no improvement.
The firmware is version 7.5 and it appears there is no older firmware to revert back to for this model.
I have an older Airport Extreme n Gigabit model which achieves 7 to 12 MBytes / Second transfers over WIFI and at least 20MBytes / Second over ethernet to ethernet using the same clients, in exactly the same location etc.
Do I have a faulty unit and does it need to be returned? It is only 2 days old and want to sort it out within my 7 day return policy.
Thanks for any help.
Cheers
Cat

Sorry folks, I seem to have worked it out.
I found on another thread that saving the setup info as a profile and re-loading the saved profile has helped some people. This appears to have cured the slow transfers for me so far.

Very slow network file transfer speeds

We just moved and I've now connected our imac and macbook to our network. This time rather than running cables I thought we'd run the imac and the macbook off of our airport extreme. After a bit of repositioning and fiddling I've got a strong signal throughout the house and the internet connection is great. The problem I'm having though is network file transfers are really, really slow. I can't get anything over 2MB/sec on either mac, and it is way slower on the macbook than it was previously. From NetStat it looks like there are some bad connections and overflows, is there anything here that might point to a problem? Thanks in advance for any suggestions. NetStat results for tcp:

Very slow network file transfer speeds with WRT310 + Powerline PLS300

Hi guys-Thanks for looking!
I have Charter hi-speed (10MBS) with my wireless N router (WRT310). Connected to my router is the PLE300 Linksys powerline adapter. I have two PLS300 powerline adapters. One feeds my computer and my wife's computer in the den and the other feeds the playstation, xbox, NAS Black Armor media server in the media room.
In running speed tests online, I get >10 MBS on both ends of the powerline adapters so surfing the internet is very fast on both ends. I also have very fast file transfers from my wife's computer to my computer across the same PLS300 adapter
However, in transfering files to my media server from my computers, I get speeds of 500 kbs. If I try to stream video files (non-HD) to my PS3, the video stutters to where it is unwatchable. I have also tried to bypass the powerline adapter by just using a wireless N gaming adapter and that yielded similar slow results.
I am running Windows 7 on both computers. I have removed the firewalls and McAfee.
Again, thanks for looking and happy new year!

Reduce the MTU to 1350 on the router and check if that helps...

New router fixed my slow my data transfer speeds

I've been living with a relatively slow internet connection for over a year without knowing it. When I moved here I had FiOS 50/50 installed. I didn't realize a big boost in speed compared to what I had before. But up until a month ago, I had been a light user. Only occasionally connecting a tablet or phone through Wi-Fi. I got a new computer lately and started transferring files via FiOS from a very fast and reliable remote server. I knew right away something was wrong.
To make a long story short the problem turned out to be the wireless router. At the time of installation, the router was actually an old model. I had no way of knowing this because the Verizon "My Services" page said I had a more capable piece of equipment. Besides being dated hardware, it evidentially wasn't working as well as it should have. Here, we willl fast forward through the processes of rectifing the issue to receiving the new router.
I am happy to report that considering the variables, I am getting the speeds I was expecting. To confirm this the speed and diagnosic reports are awsome. Doubled the download speed of the old router connected by wire from <25 to >50. Better than 7X the speed connected by Wi-Fi from <7 to >50.
It took considerable effort to resolve but it was worth finding out if these incredible speeds are achievable. And, they are.
Thanks for reading.

So what router did you get? Was it the Fios Quantum Gateway?

Very slow and bumpy USB3 transfer speed

Hi all,
I have a WD external usb3 hard disk and I am experiencing slow and bumpy transfer speeds as you can see from the screen shot (it starts fast but then falls down to few KB/s ...this is really frustrating):
h t t p: //s10.postimg.org/abm42k1kl/usb3_slow.jpg
If I do the same thing on my older PC with USB2 it works just fine, I mean constant speed of around 70mb/s
My Specs:
Mobo: Z97 G45 Gaming
Source hard drive: WD Caviar Black 2TB
Windows 8.1 64 with all updates
intel i5 4670k
8gb ddr3 1333
I checked to see if there is a specific usb 3 driver for Z97 chipset but I couldnt find anything. Any ideas? Or maybe it is some settings in the bios which makes this problem?
Thanks in advance for your reply!

Homehub 3 Transfer Speeds

Hi All
My home setup has a Homehub 3, with a gigabit cable coming out of the gigabit port, into an old Netgear router that I'm using as a switch, and from that I have a media PC, and homeplugs coming out of the switch. The homeplugs link my network to a server, and 2 WDTV Live boxes around my house.
I've recently upgraded my Comtrend 200mbps to TP-Link 200mbps homeplugs, and upgraded my Dlink NAS to a HP server.
My transfer speeds have gone up from 6mbps to 8mbps, when I'm copying data from my media PC to my server and back.
I also bought a TP-Link Wireless N USB adapter last week, in the hope that I could get significantly better speeds between my PC and server, however, after changing every setting on my Homehub (N, mixed mode, manually shifted channels) I can only get 3mbps. The Homehub sits downstairs, and the server sits upstairs, probably about 15 feet away in a direct line - no major walls. I even went direct from PC to homehub via the gigabit switch, but the speed was unaltered. I finally turned off every other device possible to avoid interference, but it made no difference.
I've always assumed that the Dlink NAS was the weak link in my network, but I've upgraded that (HP Proliant server with 2mb of memory). I then assumed it as my homeplugs, but I've upgraded those. I therefore assumed it was my house wiring giving me poor speeds. However, now that I'm only getting 3mbps from a USB N adapter I'm starting to think that it's the hub.
Has anyone got any experience of hub transfer speeds via homeplugs and USB N adapters? Can anybody give me any suggestions as to how I could improve my speeds (new router)?
Thanks in advance!
Simon

Nobody?
Is the Homehub 3 releatively slow at data transfer speeds when copying files arounf my network? Would there be any benefit to me purchasing a new modem router to replace my BT HH3?

V. Slow transfer speeds with new dual band Airport Extreme

I have a new Airport Extreme (late 2009, dual band, full 'N' spec) which I am using to replace an older Airport Extreme (early 2008, 5Ghz, 'draft' N).
I have a USB disk attached and was interested in benchmarking the transfer speed of the new Extreme, compared to the previous version. The results are puzzling / alarming.
Shown below are transfer speeds (file copied to the attached USB drive) under different connection standards (2.4Ghz / 5Ghz & a/b/g/n)
'Old' Airport Extreme
5Ghz - 'draft' N : ~5-7 Mb/sec
'New' Airport Extreme
2.4Ghz - b/g : ~3-5 Mb/sec
5.0Ghz - a : ~3-7 Mb/sec
5.0Ghz - N : ~200 Kb/sec
Hence transfer speeds appear to collapse when I try to make use of the 'N' spec with the latest Extreme. I have tried altering items such as - wide channels (on / off), interference robustness (on / off), 5Ghz channel (manual, instead of auto), with no upside.
I seem to be at the point of concluding that either
1. I have a 'broken' Airport Extreme
2. The WiFi card on my early 2008 iMac (which implements I guess the 'draft' N standard) is 'incompatible' with new the Airport Extreme under a 'N' connection.
Any thoughts ?

Since all devices in my wireless network are capable of latest 802.11n protocol, I really do not need older and slower 802.11a/b/g protocols. To achieve above 200 Mbit/sec, 5GHz band with wide channel option turned on is really necessary. Thus I really wish I can turn off the 2.4GHz radio band (seems Apple has set this band as default) of my new dual band Airport Extreme to avoid unwanted bandwidth degradation. Unfortunately this is not possible with radio mode setting in Airport Utility.
The best I can do to force connection with 5GHz radio band (with quite consistent result) is as follows:
On Airport Extreme through [Airport Utility>Wireless] :
Radio Mode: 802.11n only (5Ghz) - 802.11b/g/n
More Options>Wireless Network Option>Transmit Power: 100%
More Options>Wireless Network Option>Use Wide Channels: checked
More Options>Wireless Network Option>5 GHz Network Name:
checked and same network name with extra suffix "(5 GHz)"
On 27" iMac through [System Preferences>Network>AirPort>Advanced>AirPort]:
Preferred Networks:
Create only one profile in Preferred Networks for the above network name with suffix "(5GHz)"
Uncheck the option [Remember networks this computer has joined] to ensure there is only one profile under Preferred Networks .
Once all above settings are done, restart Airport Extreme in Airport Utility. Your computer should connect wirelessly to the base station through 5GHz band after booting most of the time. Even when it is not occasionally, simply go to the Airport icon in main menu bar and click on the network name with suffix "(5GHz)" in dropped-down list to connect manually. With all these settings, I have achieved 300 Mbit/sec bandwidth on my iMac most of the time for fast Time Machine backup.
How I wish feature for better radio mode control by end user will be implemented in next update of Airport Utility. Apple should trust end user's brain better than artificial intelligence (or ignorance ?) in wireless network implementation. Wireless traffic between the two radio bands and among various wireless devices should be segregated specifically in Airport Utility by end users whenever dual band Airport base stations are in use.

Transfer speed to Airport Disk?

I have a 300GB LaCie connected to the USB2 port on my Airport Extreme Base Station. So far, this arrangement seems to be working fine in Leopard--but I'm wondering if the data-transfer rate is abnormally slow.
I have the Wireless Radio Mode set to 802.11n (802.11b/g compatible) (unfortunately, I can't go 802.11n only, or my TiVo can't connect), and the iMac I'm on is only a few feet away from the Base Station. I'm transfering a 3.5GB iMovieHD file from the iMac to the 300GB LaCie right now, and the total transfer time is about 42 minutes. Does this seem normal?

There's a bit of confusion in this thread about speeds.
Data transfer speeds are sometimes given in MegaBITS per second Mb/s and sometimes given in MegaBYTES per second MB/s. (it's easy to get them confused)
The Airport Extreme's wireless is rated at 270Mb/s.
That number does not reflect real world use (but all manufacturers use the theoretical value) What it means is that this is the maximum number of bits per second going in both directions including all the overhead stuff.
What is the maximum real world speed? In the real world the best speed you'll see copying a file from one place to another is 10MegaBYTES per second. This is very fast wireless very similar to wired ethernet. It can only be achieved when the Airport is set to 5GHz radio mode.
The USB hard drive does not achieve this speed. The CPU in the base station struggles to cope with files systems and the drive. So reading and writing you get between 3 and 6 MegaBYTES per second. The same drive would be 4 or 5 times quicker if it were plugged into your computer.
Using a NAS is faster. But this is plenty fast enough for streaming HD videos.
Jon,
Your speed is about half the regular speed for copying. Not massively slow but slower than I'd expect.
Try connecting at 5GHz n-only.
And use the graph device in Airport Utility to see if you have a poor signal strength.

Slower Network Transfer Speeds with .7

Since upgrading to .7, I've noticed slow transfer speeds. For example, when transferring one large file, I get 11MB/sec on average. When transferring a bunch of smaller files, I get about 1 - 1.5MB/sec. I remember is being faster in .6
This is transferring files from my Mac Pro to my Time Capsule, using Gigabit Ethernet.
Can someone let me know what speeds you are getting when transffering a large file from a Mac Pro to a TC and also a bunch of small files from a Mac Pro to a Time Capsule. (or any NAS drive)
I used Activity Monitor to test the speeds. Thanks.

Does your PC have a FireWire port? you can use IP over FireWire for better throughput than the wired ethernet.
You can't use link aggregation in this case since it requires multiple interfaces of the same type (e.g. two gigabit ethernet cards), but you cannot mix media such as AirPort and Ethernet.
The alternative would be to install a gigabit ethernet card in your PC. You'd at least then get gigabit ethernet speed between the two devices which is also a step up.

Slow transfer speeds between two macs

The general setup: an iMac Intel 20" and an iBook G4 1,2GHz connected via an Airport Express (newest edition), both computers running 10.4.7.
When trying to transfer files via AFP between the two on my local network, I get "tremendous" speeds of about 0.5-1 MB/sec. Why is this so incredibly slow? Is it because of encryption or something similar? I can download off the internet with greater speed than that!

i have exactly the same problem , using a macbook black g1 . slow network speeds and flakey internet . these were ok when I first got the machine . but are now slow as . using the network view of menumeters I see that if i try and shift files from my mac mini they are incredibly slow with menumeters show 0.0kb/s for seconds at a time .
to trouble shoot this problem I used another friends macbook configured with exactly the same settings on this network and the transfer speeds were as they should be which was about 1.5-2.5 megs/sec .
so i figure there is some preference corrupted but which one ?
I have experienced several crashes recently . because of the overheating bug I have the fix applied to my machine and the firmware update . Maybe the network preference got corrupted at that point .
any tips as to which preference to delete would be appreciated .
