Slow file copy

My mac is almost unusable when copying large files and the spinning
beachball keeps on appearing. It took me 18 minutes just to copy a 1.7gb of music. I tried resetting PRAM, VRAM and SMC and nothing happened.

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.

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 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

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.

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)

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?

Webutil_file.copy_file slow in copying files

Hi All,
I've read about this problem previously and I'm finally suffering from it myself.
It took between 5 and 10 minutes to copy a 500k file between two network drives connected to my client. How slow is it going to be for the 100Mb files we will want to copy?
Has anyone found a solution? IS the only speedy alternative to use client_host and the copy command? I was hoping that the webutil_file.copy_file was a more elegant solution to the file copying process!!!
TIA
Tony

Hello Tony,
That would be fine if I wanted to transfer from the AS to the client.
But I want to transfer between two network drives on the client,
these drives are not visible to the AS at the moment.My understanding is that the functions are executed on the client and therefor the network drives have to be visible to the client and not to the AS.
But currently i'm working in the OC4J and my server and client are the same.
So it is not really tested.
Is the AS to client copy much faster than the copy_file on the client?
Why would that be? Is it access to network drives on the client that is slow?Yes it is faster. The procedures use different implementations. Files don't get divided in chunks when webutil_file_transfer.AS_to_Client is used.

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.......

KDE4 File copy really slow

When I copy a file, using KDE 4.6 and dolphin (or konqueror even), from a remote location (ssh, smb) the download tops out at 220KiB/s.
From the commandline, I'm getting 4-10 MiB/s. Any idea's as to what can be happening?
I thought it was my wireless at first, but then I thought, if it was the wireless, the problem would happen on the commandline as well.

Hi The RealBlood,
Please provide more information for better analyzation:
1.Does this issue occur when you transfer large file like .zip? Will this occur when we compress the video file to zip file?
2.Does this issue only occur when transferring file from Windows 7 to Windows 8.1 or also in the other direction?
We could set Large Send Offload v2 (IPv4) and Large Send Offload v2 (IPv6) disabled, and then check if the issue exists.
For more information, please refer to the following thread.

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?

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...
