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 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.

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.

File copy speeds to CSV vs non-CSV

I'm working on bringing up a 2012 R2 cluster and doing a basic test. In this cluster, I have two adapters for iSCSI traffic, one for network traffic, and one for the heartbeat. Cluster node has all the current updates on it. Everything
is set up correctly as far as I can see. I'm taking a folder with 1GB of random files in it and copying it from the C: drive of a node to an iSCSI LUN. If I have the LUN set up as a non-CSV disk, the copy happens about three time faster than if
I have it set up as a CSV disk. All I'm doing is using FCM to change the disk from CSV to non-CSV (right-click, Remove from CSV, right-click, Add to CSV). I can swap it back and forth and each time the copy process is about three time slower when
it's a CSV. Am I missing something here? I've been through all the usual stuff with regard to the iSCSI adapters, MPIO, drivers, etc. But I don't think that would have anything to do with this anyway. The disk is accessed the same with
regard to all that whether it's CSV or not, unless I'm missing something. Right now, I only have a single node configured in the cluster, so it's definitely not anything to do with the CSV being in redirected mode.
I'm not trying to establish any particular transfer speed, I know file transfers are different than actual workloads and performance tools like iometer when it comes to actual numbers. But it seems to me like the transfers should be close
to the same whether the disk is a CSV or not, since I'm not changing anything else.

Which system owns the CSV? If the system from which you are copying does not own the CSV then all the metadata updates have to go across the network to be handled by the node that does own the CSV. If you are copying a lot of little
files, there is more metadata.
Actually, metadata updates always happen in redirected IO from what I'm reading, that has been the part that I was missing. This explains it.
https://technet.microsoft.com/en-us/library/jj612868.aspx?f=255&MSPPError=-2147217396 "When certain small changes occur in the file system on a CSV volume, this metadata must be synchronized on each of the physical nodes that access the
LUN, not only on the single coordinator node... These metadata update operations occur in parallel across the cluster networks by using SMB 3.0. "
So a file copy, even when done on a coordinator node, does the metadata updates in redirected mode. Other articles seem to say the same thing, though not always clearly. So it's still accurate to say that a file copy isn't the best way to measure
CSV performance, but there doesn't seem to be a lot of pointing to the (I think) important distinction regarding how the metadata updates work. From what I can see, that distinction is probably trumping anything else such as who is the
coordinator node, CSV cache, etc. For me anyway, it makes a 3X performance difference, so I think that's pretty significant.

Slow file transfer speed on OS X / Windows LAN

I have a Mac Mini with OS X Server (Yosemite) on a network of 5 Windows 7 PCs, the server hosts FileMaker Server 13 and also some files in a shared folder.
I notice the file transfer speed when copying a file from one PC up to the server's shared folder is around 350KB/second, is this an acceptable speed? how could I improve it?
Thanks for your help.

I'm having the same issues.. I recorded a bunch of video with the 4s.. now i'm copying them to my windows 7 pc with it peaking out at 900KB/sec. My corsair thumb drive in the same port gets 5-10x this speed. any luck getting faster speeds?

Very slow file download speeds

Whenever my computer is trying to load movies or download files, the speed at which they download is extremely slow.
On a file I'm currently downloading, the average speed is around 120 kB/s, and I'm lucky if I can get it up to 20. Also, movies, like in YouTube, take at least ten minutes to download, even if the movie is only a few minutes long.
Obviously, this is very frustrating, especially because I haven't always had this problem.
My surfing speed is fine, it's a bit slow but I'm not complaining, I just hope someone has a solution to this slow downloading problem?

I was going to agree and say, yeah let's blame it on Vuze or the file, but that doesn't explain why the YouTube videos, along with any videos on any other site, download so slow.
How would I go about restarting the modem (I have 2Wire at my house)? And is there a chance that would help? I wasn't sure because of the fact that my other computers are fine, but it's worth a shot.

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 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 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:

IDSM-2 slow file copy

Hi, I have FWSM and IDSM/2 module on 6500 switch in my network, and we have issue with file transfer between some machines. When server is behind IPS, transfer is very slow, 40x lower then in situation when server is only in VRF/FWSM - without IPS. Any idea? Thanks in advance

an overworked sensor can certainly be a cause of problems. The easiest way to determine you sensor's health is to look at the % missed packets and CPU utilization from the CLI:
sh int (%missed pactets)
sh stat host (CPU)
If those don;t look like the cause of your problem, a likely cause is the normalizer engine sigs. These sigs will drop packets it doesn't like and not give you an alert. Check what sigs are fireing when you're experiencing this problem:
show event past 01:00 | include (whatever you're looking for)

Slow HD Copy Speed

Hi i have a MSI Neo 925X, my primary drive is a 200GB SATA Maxtor, then i have one 80 GB Segate.
When is connet the 80 GB to the Blue plug, and even if the boot order is selected to boot from the SATA, it just doesn't boot from it, it keep on saying Please insert Boot disk. Thus i have connected the 80 GB 2 one of the yellow IDE ports, now only my DVD Writer is conneted to the Blue port.
I Windows Xp Pro SP2, i takes my about 30 - 40 to copy stuff from a dvd, and it take about 2 - 4 hour to copy about 10 GB worth of data, please help, i have checked, and i have check, Auto detection for DMA is enabled, and DMA is selected.

well wat speed is the 80 gig ata 66 ata 100 ata 133. If it was say 66 i can see it taking 2-4 hrs to send 10 gigs. You can only go as fast as your slowest hd. A trick that might let you connect the 80gig to blue is copy your boot.ini to it from your other drive and it should boot my boot.ini is stored on a 30gig were my os is on a 160 but if i delete the 30gigs boot.ini i get problems like you with booting.

MacBook slow Wifi (file copying)

Hi there,
I'm running a 802.11n 2,4GHz Wifi at home. My Mac Mini (2011) and Macbook (2007, white) connect to my network using it. My server is connected through gigabit LAN.
Using my Mini I get very decent speeds copying files, a 700MB file takes just a few seconds to copy. But using my Macbook speeds are incredibly slow.
The same file takes minutes to copy.
I've tried changing the Wifi channel and also the router without success. It seems to be a problem with my MacBook. It's running 10.6.8. Had 10.7.4 installed before, wasn't better. The Mini of course runs 10.7.4.
I also remember connecting the MacBook to a friends Wifi in 2008 who already had 802.11n and it was ultra fast. So it should be able to handle it.
Any ideas on how I can get better speeds?
Tried several channels, no interferences, signal is full bars on both machines which are sitting next to each other by the way. So no physical objects blocking the MBs wifi. Also did a clean install on 10.6.8.
Help!?

Thank you for your reply.
I think we have the very same Macbook.
As yours mine is maxed out with 4GB of installed RAM, where 3GB can be addressed. Same specs as you see.
Also I'm not running anything except Finder when testing. Currently there's plenty of RAM free. With Safari, Mail and iTunes open I still have 800MB free.
I'm going to install Leopard or even Tiger on a spare partition, just for testing..
By the way, did you try Lion? Even in 10.7.4 I had Wifi drops on wakeup plus the same slow file copying speeds..

Errors and slow performance copying lots of files between large hard drives

After upgrading to Snow Leopard, I have VERY slow file transfer speed with external eSATA drives. While trying to upgrade from a 1.5TB drive to a new 2TB drive, the copy took almost 24 hours and then failed on a large Fusion virtual OS file.
So I removed my eSATA card from my Mac Pro and connected the drives via FireWire 800. Same issue. I have the 10.6.1 update and reset the PRAM with no improvement.
Tried doing the copy with SuperDuper, and I have the same speed issue, but checking their log I see some of the files that Finder tried to copy, SuperDuper found another way to copy. Others it fails on. Here's a log of one of the files it could copy (but Finder couldn't):

There is indeed plenty of space left on the device... over 1.5TB in fact.
Not sure what is going on here. I have 4GB of RAM, and heard Snow Leopard needs twice as much as Leopard. Am I running out of RAM due to the large amount of files? Or is it some incompatibility with large drives and Snow Leopard? I did not have these problems with Leopard, and I was using these same drives.

I, too, am experiencing extremely long copy times (17 hours on 5GB) when copying numerous (200+) files from an external HD via FW 400. The same happens when I try to copy files using FW 800.
Is there anything I can do to reduce the copying times?
