TC slow wired file copy

Hello,
I am trying to copy files to my TC connected with ethernet. It takes about 15 minutes to copy a 500meg file. The transfer rate will speedup and slow down dramatically during the copy. Has anyone seen this behavior? The TC is almost useless as an network storage device with this slow transfer speed. Thanks

I am having a similar problem here with the new dual-band TC on 7.4.1. My speeds are way below what I expected. I heard that the new firmware causes slowdowns, but I wasn't able to find TC 7.4 anywhere to roll back to. For me, the speeds of file copying vary between 1-4MBs on wireless and 6-8 on ethernet. And if I copy from TC to an HFS+ formatted USB Disc directly connected to it, the speeds are between 1-2 also, sometimes even slower (and I thought I'd get full USB speeds this way!). This seems terribly slow. Sometimes the HDD in TC shuts down when I am copying between it and the USB disc connected right to it (you can hear the sound of the HDD slowing down and stopping) - and I have to wake it by opening a file already on it for the copying to continue.
I will try to backup all my files on TC somewhere else and erase it from AirPort Utility, as there was an advice somewhere that formatting the disc might help. I sure hope that my device is not broken, as I'd truly hate to have to make warranty rounds...

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..

File Copy Dialog box hangs in mid-copy; Cancel does nothing.

Hi all,
I'm having the aforementioned issue fairly often with Windows 7. It seems to happen when copying to network shares. It is more than annoying--it is literally stopping production at our company. I would really appreciate an realistic fix
for this--that is, one that isn't the catch-all "Reinstall windows".
Let me further state that it has nothing to do with hardware--I can reliably copy the same files in XP. It is a Windows 7/Explorer thing.
It also seems to be size-related--but I haven't had the time to do scientific testing to verify this. I know that if I'm copying an Access .mdb file from my development machine (Windows 7) to a client machine (mostly windows XP) with a mapped drive,
it seems to hang. But if I compact/repair the .mdb file and bring it from, say 25 meg to 12 meg, it seems to copy fine.
Worse, is that when it hangs, I'll finally hit "Cancel" after a few minutes, and then the entire Windows 7 locks!! I can't do anything until I ctrl-alt-del and kill the Explorer.exe process, which wipes out my desktop, etc, until Explorer.exe auto-starts.
This is such a huge problem that I have to think there's a fix upcoming.
Thanks,
--Jim

Hi,
May I know how it works if you copy files between local drives? Please also boot the system to Safe Mode with networking and check this issue.
In addition, may I know more information about the machine which hosts the share folder you mapped is located, a Windows based computer? Please also
let us know the operating system.
Based on my research, I would like to suggest the following:
1.
Try disabling Receive Side Scaling, Chimney Offload, and NetDMA support and see if it works:
Information about the TCP Chimney Offload, Receive Side
Scaling, and Network Direct Memory Access features in Windows Server 2008
2.
Also run the following commands in Windows 7:
netsh interface tcp set global autotuninglevel=disabled
netsh int ip set global taskoffload=disabled
3.
Try Robocopy:

TC wired file transfers of small files unusually slow

Wired file transfers from my MBP to my TC are unusually slow (several hours for a home directory of a couple of GB's).
When transferring a single large file, the transfer does seem to go fast (less than a minute for a 500 MB disk image).
Is this a known problem?

File copy over AFP / SMB very slow on Mavericks

Hi guys.
I have a retina macbook pro (early 2013) and a mac mini (late 2012).
Both are running 10.9.1. The mac mini has OS X server installed and 2 USB 3.0 harddisks attached to it in RAID0.
I have a Thunderbolt display hooked up to my MBP. I have a 1gbit wired network between the two machines.
Now comes the problem: file copy from the USB 3.0 RAID array to the macbook pro over AFP or SMB is slow, I only get around 8 MB/sec.
First I thought it was a wiring issue (I created my own ethernet cables). However, I tried copying the file via SCP (i.e. SSH) and then I get 50 MB/sec. Still not close to the maximum for gigabit, but at least a lot higher than 8 MB/sec.
I tried googling if anybody else has the same issue, but couldn't really find definitive answers.
I have tried everything with both jumbo frames of and on. Both give the same results.
What's even stranger is if I connect my MBP over 5 GHz to my airport instead of wired, I get 20 MB/sec over AFP....
As far as I know the problem did not arise in the pre-Mavericks time.
Does anybody have any suggestions or solutions? 8 MB/sec is not really that nice

Have you checked your ethernet speed/duplex settings on the ethernet port and XP machine?

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.

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

Simple Bundle file copy slow and inconsistent

We are running ZCM 11.2.3a and are experiencing slowness with some bundles.
We have a simple bundle to copy a small file to the workstation.
Sometimes the file copy is abnormally long and other times it's instant for the same bundle.
Any ideas why this would be happening.
Thanks

Try enabling Debug Logging and ZMD-Message logging to see if that helps.
Also -
Try setting up a test Location for a Device and only point that location
to Server1 for everything. Then Server 2.....
Look to see if one server is giving u issues.......

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.

File copy slow, extremely slow

Hi everybody,
I'm facing a strange situation where file copy from an external drive (USB) to my hard drive (a macbook pro late 2008) is extremely slow.
I'm trying to understand what is happening and got here to get some help from experts ^^
The problem arises on some files only and is not specific to the external hard drive I use.
Once a file start to copy slowly, cancel the copy and start it again does not help. It's like the system finds it hard to copy this file.
It is generally very large file (over 5Gb).
I've used the disk utility to check the hard drive but every thing is ok.
I'm currently trying to copy a 35Gb file. The ETC is 74 hours !!!
Can somebody help?
Thanks
Pascal

Thanks Chris for your answer.
I did rest the PRAM but it does not help. I just tried to copy the same file and the ETC is 305 hours
An other idea?

ThinkPad USB 3.0 Dock and X1 Carbon SLOW wired network speeds

Got my X1 carbon, like it don't love it. However using it on our wired network I'm getting around 20MB speeds copying files and my carbon becomes very copy when doing large 2GB file type copies.
On my T420s with a "real" docking station I get around 150MB speeds copying the same file.
No errors on our Cisco switches, seem speeds are locking in fine. Is that simply the best I'm going to to over the USB 3.0 connecting to the SS port? I can almost live with slow speeds but copy video during copies, no way.
Am I missing something, doing something wrong, or this is what it is? Sure hope not...

I'm seeing the same issue with a ThinkPad W520. When I connect my ethernet cable directly to the laptop, my internet speeds are on par with my service provider of 18 Mbps. When I move that cable to the dock, I will only see 1.5 Mbps. I have two displays attached to the dock and I'm running Windows 7. I've updated the dock firmware and have installed the latest system drivers. Is there anything else to try?

File Copy times

My newsreader is acting funny and dropping posted messages, so I
apologize if this shows up twice.
My comments on the file speed are that the times posted by other just go
to show how difficult it sometimes is to make good timing measurements.
I suspect that the wide variations being posted are in large part to
disk caching. To measure this, you should either flush the caches each
time or run them multiple times to make sure that the cache affects them
more equally.
Here is what I'd expect. The LV file I/O is a thin layer built upon the
OS file I/O. Any program using file I/O will see that smaller writes
have somewhat more overhead than a few large writes. However, at some
size, either LV or the OS will break the larger writes into smaller
ones. The file I/O functions in general will be slower to read and
write contents than making a file copy using the copy node or move node.
Sorry if I can't be more specific, but if you have a task that
seems way to slow, please send it to technical support and report a
performance problem. If we can find a better implementation, we will
try to integrate it.
Greg McKaskle

Maybe this is because of the write buffer?
Try mounting the media using the -o sync option to have data written immediately.

File copying problems

Copying some files using the Finder results in a dialogue box error message: "The Finder cannot complete the opeeration because some data in +(file name)+ could not be read or written. (Error code -36). The same files copy without error when using SilverKeeper (v.2.0.2) backup program.
I am also experiencing a problem when quitting SIlverKeeper. A second or so after selecting Quit, and after the program has actually quit, a system dialogue box appears saying that the program has unexpectedly quit and offering choices of Reopen, Report to Apple or Close.
The system also seems somewhat sluggish.
Can anyone offer suggestions?

Hi John, At this point I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files!
Disconnect the USB cable from any UPS so the system doesn't shut down in the middle of the process.

Is it possible to have media files copied to a new location as you import them into a project?

I have roughly 800gb of footage i've taken over the past 2 years of traveling, and I am making a single video montage... The files are located on an external drive, making them slower to work with. I have a 1tb ssd but not enough free space to copy all the files to it for sorting. What i want to do is have the files copy over to the SSD as i add them to the project, so that only the footage i'm going to use gets copied over to the SSD. The only way i can determine if i am going to use the footage or not is to scrub through and mark Ins and Outs in premiere...
So i guess my question, in the simplest terms i can ask is, Is there a setting in Premiere, like the project manager tool which allows you to consolidate used media files to one destination, but one that will consolidate files as you add them to the project? or could i do this manually by repeatedly using the project manager tool to consolidate files periodically?
Hope that makes sense...
Oh, and yes, i have considered other methods to my madness, like reviewing the footage outside of premiere before deciding if i will use it or not, frankly, i have over 4000 pieces of footage and it's just much faster to scrub through them in premiere than to open each one in vlc to review. It's also much more convenient to mark my ins and outs as i review the footage, so premiere is my only option.
Thanks!

You can easily (and better, IMHO) do what you want in Adobe Prelude. It's part of the CC subscription, and may have been included with CS6.
Open the Ingest panel, navigate to the external drive where you have your source clips, make the thumbnails in the Ingest panel comfortably large, click a video clip to enable scrubbing, and use the J-K-L keys to navigate playback through the clips. Put a check mark on the clips you want and be sure to select and set up the Transfer option on the right side of the panel before ingesting. Don't select the Transcode option.
Cheers,
Jeff

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.
