Extremely slow file copy

Have a NAS and copying a file to it is taking forever! I saw a 258 GB copy start up and register 480 days estimated time!

are you connecting to the NAS via ethernet or WiFi?

Extremely slow file copying over airport extreme network

Hi,
I have an Airport Extreme Base Station (10/100) network, also connected to the internet. When copying files from my MacBook Pro to a USB drive connected to the base station, OR when copying files to another computer (a windows machine) the throughput maxes out at about 700 KB/sec which is 10 times slower than when copying to the USB drive connected directly to my MacBook Pro. Although I have updated everything to the latest and greatest versions, I still have very slow file copy speeds. It's always been this way. I've read dozens of threads for potential fixes but none of them have helped. I am using Activity Monitor to measure the throughput and also timing the copy of a 10GB file. At these speeds, that file takes 4 hours. Useless.
My base station is within a few feet. I've tried different channels, 2.4GHz, 5GHz, getting rid of WPA, you name it. At first I thought it might be some issue with the USB drive connected to the base station, but copying to another computer on my network is the same. It is very frustrating.
Any insights would be greatly appreciated.

Thanks. I thought about buying the TC but I'm worried that if my network is operating slowly, which it appears to be, that I'm not going to get the throughput. I also noticed that my windows machine which is on the same network accesses the internet faster as well. I'm wondering if it is something with my MacBook.
BTW - I went to school in Pittsburgh. Great great town.

Extremely slow file copy from USB 3 external Seagate on MacBook

I copied my iPhoto file of 20GB onto a new Seagate USB external drive from my 2011 MacBook in about 20 minutes over USB 2.0. I am copying up the same file from the same drive on my newer 2012 MacBook pro and it is taking 7 hours. The newer MacBook has a 750GB SATA SSD and is equipped with USB 3.0. Why would it take so much longer to copy from the drive to the newer Mac using a faster USB spec?

Well, I solved this myself with some searching on other threads. I turned off Spotlight indexing on the drive, and killed the copy job, disconnected and reconnected the drive, and the copy is now going quite fast. Will be done in lest than 5 minutes.
System Preferences> Spotlight>Privacy> Press the + and added the external drive.
Apparently, this is the default behavior of Spotlight, and the indexing was causing the bottleneck.

Extremely slow file transfer from wifi server to MacBook Pro

I am experiencing extremely slow file download speeds from my wifi server to my MacBook Pro. I have just carried out a test - transferring a 16.5Mb folder took 8 mins, 24 secs. Transferring the same folder to my iMac G5 takes less than 3 seconds. Also, copying the same folder from my MacBook Pro to my wifi server only takes 22 seconds. Any suggestions PLEASE!!!!!

Try getting it on the Mac using something other than iPhoto.
In Windows, it would simply be a matter of opening Explorer and copying the file(s). I'm fairly certain that Mac has a similar feature, but I'm not familiar with Macs.
Not really an iPhone issue... more of an issue with the application being used to import the file.

Slow Files Copy File Server DFS Namespace

I have two file servers running on VM both servers are on different physical servers.
Both connect with dfs namespace.
The problem part is both servers never have same copy speed.
Sometime very slow files copy about 1MBps on FS01 and fast copy 12MBps on FS02.
Sometime fast on FS01 and slow on FS02.
Sometime both of them slow..
So as usual I reboot the servers. Doesn't work.
Then I reboot the DC01 also doesn't work. There is another brother DC02.
After I reboot DC02, one of the FS become normal and another FS still slow.
FS01 and FS02 randomly. They never get faster speed together.
Users never complain slow FS because 1MBps is acceptable for them to open word excel etc.,.
The HUGE problem is I don't have backup when the slow FS days.
The problem since two weeks I'm giving up fixing it myself and need help from you expert guys.
Thanks!
DC01, DC02, FS01, FS02 (Win 2012 and All VMs)

Hi,
Since the slow copy is also occurred when you tried the direct copy from both shared folder, you could enable the disk write cache on the destination server to check the results.

Windows Explorer EXTREMELY slow at copying files from network, but robocopy works

Hi guys,
I'm having a REALLY BAD performance issue when copying files over from SAMBA 4 to any Windows 7 computer. To copy a folder containing 50 files with a total of 10 MB using the explorer it takes about 20 minutes (!!) at a rate of 3-5 KB/s, but when using robocopy
the same folder takes like 3 seconds to complete. Also, the issue does not occur with older versions of Windows, like Windows XP and Windows Server 2003.
Please please please come up with some ideas except the usuals like disabling Remote Differential Compression, disable autotuning using netsh, setting local security policies for NTML authentication or trying new switches / upgrading network drivers or windows.
I DID IT ALL, but nothing helped!
Thanks in advance!

Linking in your post over on Server Fault in case it gets resolved over there first ;)

Slow file copy speeds

Hello, I can't ul or dl files from client to me or vice-versa faster than 70kbs. Both connections are static, both are 7mbs up and 2.5+mbs down and both isps have assured me that no throttling is taking place. Ports are set correctly, encryption is off for file copy; I am only one guy managing one machine for my dear gray haired mother. The files are huge 300megs plus (.psds with necessary layers, etc.) but it doesn't seem to make any diff. if I copy 1 at a time or zip a bunch-- no faster than 70k and usually 50k. Routers on both ends say connected at 7up/2.5 down and any ftp client flies to and fro. It is just much more convenient to use ARD 3.2--
Gracias, Dennis

Welcome to the Discussions Dennis,
Are you using the Copy command while also Viewing or Controlling?
Things that I can think off of the top of my head that could be slowing things down (on one of the machines):
bandwith use from screen sharing
A FAT formatted drive
encrypted user or folder
difference in OS (10.5 to 10.4 - sad but true at times)
encrypted transfer (which you covered)
3rd party firewall / security sw
I've also seen where you may be able to do a good speed test, but due to router port forwarding using ARD to transfer files is slow, so that would be one other thing to check.
Sorry I don't have a know cause. I hope this helps, JD

Extremely slow file downloads from the 'net (Pavilion G5460uk)

We have an HP Pavilion G5460uk desktop with Windows 7 (64-bit) updated to SP1 and current, and use IE10 and Chrome. Protection is by Norton360 supported with Spywareblaster and Spybot S&D, and also access to Norton 'Eraser', ESET scanner and Sophos virus remover. The PC is ethernet-cabled into the router but with also use other laptops etc wirelessly (all all these are working fine, with the same antivirus setup etc, without the problems we have on the HP desktop).
Performance on the internet seems fine EXCEPT that the desktop is now extremely slow at downloading any files (to the point that it is timed-out on the servers). It is impossible to download anything large onto it directly from the 'net(we are using the other PC's to transfer files) - although MS updates seem to get on OK.
We tried HP 'Support Assistant' which recommends two updates: Ralink Wireless Network Controller (sp58084) & 802.11n WLAN (sp60924) updates. Of course we cannot download these directly but it is unclear whether these are relevant to the problem anyway.
It does not appear to be a network/internet, software currency or virus issue. Some setting somewhere? Please can someone advise on what now needs to be done.
This question was solved.
View Solution.

Matter now resolved! We thought that we had covered everything before bringing it here. But just one dodgy router port connection is all it takes. Thanks for your time.

TRUE CHALLENGE-Extremely Slow File Navigation

I have not been able to find any information on this topic. When I open a file from Acrobat, navigating through folders is EXTREMELY slow. It is also slow when I scan documents to Acrobat;not the scan, but navigating to the folder I want to save it in. I only have this problem in Acrobat. All other programs are instant click.

Thank you for trying. Unfortunately, the box is already unchecked. It is strange that when I access a different Acrobat/Reader on a terminal server it navigates extremely fast. When I try to "save as", or when it ask me for a file name, or when I scan someting to a PDF and it ask for a file name, it takes forever to get to the folder to store the file.

Lenovo Thinkpad X1 - Extremly slow file transfer through e-sata

Hi there! I have got another issue with my notebook - the file transfer through e-sata is extremly slow (about 5MBpS). Using Windows 7. Where could be the problem? Thanks.

Hi Gabbi,
thanks for posting. You might want to check in your control panel which Lenovo preloaded software are installed. One software which I've seem has caused this issue is the Lenovo Rapid Shield and and Lenovo Airbag Protection.
Could you try disabling them and check for the changes.
do let me know..

Extremely Slow File Menu Office 2013 (Word, Excel and PowerPoint), but everything else is perfect

I have Office 2013 installed on my Windows 8 (now 8.1) computer. For about three weeks, all programs in the office suite ran perfectly. However, an extremely annoying problem suddenly appeared, which has been plaguing me for the past two weeks: The file
menu is EXTREMELY slow consistently across all programs in the Office 2013 suite. There's a very noticeable delay, about 2 or 3 seconds, between when I click the FILE button, and when the file menu actually appears. Similarly, all options within this menu
are laggy. Typically, the program will enter an unresponsive state for those few seconds and then promptly recover. I haven't lost any data to this issue yet, but it wastes my time.
I don't have much more than the essentials installed on my computer. Drivers for my motherboard, NVidia graphics card, Office, web browser and about 6 other trusted programs.
Any and all help appreciated. Thanks.

TC Extremely slow when copying files from an external HDD

I have a new TC, everything works well. Now I am trying to copy my iTunes library from an external HDD that is hooked on the USB of the TC. The directory is well over 300GB, the estimated time of completion is 70+ hours, that can be?!
Last week I copied all my pictures from the same external HDD to another drive via USB connection on my laptop and the directory was about 200GB, it took about an hour.
Is there anything wrong or is this normal?
Thanks in advance,
Ilias

Thanks for the quick answer. I was not clear enough though, I want to copy my iTunes library onto the TC from my external USB drive. The iTunes library is to stay on the TC so that I can always access it without the need of having an external HDD always connected to the TC.
What I do not want is the library on my MacBook.
DOes that make sense?
Yes, that's what I thought.
However you connect things, the copying process is done +*by your Mac,+* not the TC.
As I said, connect the USB drive directly to your Mac, and your Mac to the TC via Ethernet if at all possible. That will still take a while, since Ethernet is much slower than USB, but at least you won't have the data going back and forth through the TC. The data will go from the USB drive to your Mac, then to the TC via Ethernet.
If you leave the USB drive connected to the TC, the data will be copied from the USB drive, through the TC, to your Mac, then back to the TC's internal HD.

Extremely slow file transfer speed

Hello,
Has anyone else had problems transferring files between computers over a 802.11g network? Recently, I found that transferring files via wireless has become incredibly slow. This morning it took about 10 min to transfer a 25MB file from my MacMini to my MacBook Pro. This was not the case several weeks ago.
In terms of updates, neither have the notorious Airport Extreme 2007-001 update installed. Though, I did have to reinstall OS X on the Mini to roll it back. The MacBook Pro does have the Security Update 2007-001 installed where as the Mini does not.
Specs:
Wireless Router: Linksys WRT54GSv4
MacBookPro - 2GHz Core Duo
MacMini - late 2006 - 1.66GHz Core Duo
Thanks

is there a way to find out why "a file is in use" / what process is using it, and kill that process?
Yes. Launch the Terminal utility and enter this command:
sudo lsof | grep "sometext"
That character after "lsof" is a "vertical bar", which should be on the far right of the row with "P". The first character of "lsof" is a lower-case letter "L". The text "sometext" should be replaced with at least part of the name of the file that seems to be locked. The quotes aren't necessary unless there's a space (or one of a few other odd characters) in the text you put in the command. After you type the text, press <return>. You'll be prompted for your administrative password.
If the culprit turns out to be Finder, try clicking on the Finder icon on the Dock while you hold down an "option" key, then choose "Relaunch".
how can I find out if some process is accessing the Time Capsule hard drive, keeping it busy and making the transfers slow?
That's a little harder. You could launch Activity Monitor and click on the "Network" tab in the lower part of the window. I'd also check the quality of the signal to the Time Capsule
If you have an Apple AirPort base station, I'd use the advice in this thread to investigate the signal and noise levels that each Mac sees, as described in this thread:

Slow File Copy from Local MacBookPro HD to Synology 270+ NAS Station

Hi,
I have been reading through a similar problem from BO, but his problem was making copies between 2 external drives.
My problem, is using Finder, copying 90Gbs from the local iTunesMusic folder, to a Music folder on the NAS, by draging 'drop. It's not a slow copy, it's... endless. I was not able also to cancel the copy by clicking the "x" on the window.
I have tried to use iTunes with the Library\Import option, it was fast at beginning, but then it gets very slow. There were around 15000 files to copy, and during 2 full days, it has copied around 7000.
I have canceled everything, shutdown and reboot, and tried to copy them through Finder by d'drop, also very slow.
It really looks that when a directory/folder has too many subfolders, Finder has to run through all the FAT, every time, and then try to make the copy.
Please help, I am a 1 year hold Mac user, I have heard that Mac didn't manage very well with "tons of files", but this is hard to accept.
Regards,
Gi

Ok, I think I've figured out the solution, to a large extent.
Apparently there is an attribute for SMB protocol that controls send buffer size and receive buffer size, on the server. On FreeNAS that is set to 16384 as default for both. I've upped it by 10x to 163840 for both, and looks like that solved the speed issue for "downloading" from NAS. Now my speed over WiFi for NAS to MBP transfer is peaking at 130mbps, and around 100mbps for "upload".
But one thing it did not solve is the consistency of the speed, while "upload" to NAS stayed rather consistent (around 80-100), the "download" transfer jumps A LOT, I'm talking a range of 500 kbps to 130 mbps, and everywhere in between. Seems to be completely random, it will sustain ~100 for some time, but at times will drop to 500 kbps, jump around for some time and then go back up to peak. Just plain random.
But at least I can now transfer 200MB file in about 15 seconds or so, on average, over WiFi.
Hoping the SMB consistency will be improved in the next OS release, but then again, I heard people were hoping for that for the past year or so. We'll see.

Extremely slow file server performance

I have a Time Capsule (1TB, late 2008) which I use as a file server. The client of interest is a Mac mini, slightly newer. The connection is 802.11n at 100+ MB/s. I can see no evidence of interfering networks.
Anyway, dragging largeish (350MB) files from the file server to the Mac mini using finder is sometimes incredibly slow (1hour +). Tranfering the same files using firefox, a file:///Volumes... URL and "Save link as" takes perhaps 5 minutes.
General network connection and wider internet access is fine.
Any ideas what the problem is?
Everything is fully updated.

Hi Dennis,
From the description a lot of open files exist which seems to be the cause. Instead of reboot, please test to manually kill these processes in MMC - Share Folders - Open Files and see if the performance will back to normal.
If so, try to find out the exact process which locked these files. Meanwhile please help collect a screenshot of open files for helping us understand the current situation.
Meanwhile we have a forum FAQ which provided most general steps to troubleshoot network performance related issue. Please see if it could help.
If you have any feedback on our support, please send to [email protected]
I tried to kill all of the open "\msftewds" files. They disappeard and then came back again. I was
unable to kill them.
How can I find out which process is locking an opened file? I'm sorry but at the moment I can't give
you a useful screenshot because at the moment we are fine with the fileserver. As soon as the problem will be back I'll upload a screenshot.
