Slow copying over network

I seem to have a major issue here. I upgraded to Leopard today using a fresh install on a wiped hard drive (I prefer it this way - I'm old fashioned ). Everything is going OK, apart from a few hiccups. One of those is to do with copying files off a network server.
I backed up all my files from my Mac Pro (totaling around 80GB) to my NAS Server (until now very reliable FreeNAS x86 box) over 100MBit Ethernet. In TIGER everything wokred dandy in both directions and the server worked fine. In Leopard it's a different story.
Over either NFS or SMB connections browsing a folder is ice-age slow, and often folder displays just fail to finish drawing. I've locked the Finder solid at least twice doing this (a feat considering AutoFS is supposed to stop it happening!). When I try to copy a folder of files it takes a very long time to collect up the files it needs, pausing often for several seconds every so often during the operation, then it starts to copy at a very slow rate, something like less than 2MB/s. It keeps pausing when it's copying and has on several occasions stopped altogether and the share has spontaneously disconnected and timed out. Copying has also locked the Finder solid on one occasion, and on several others I couldn't get the 'Copying' dialog to close at all.
Using AFP the connection is stable and works fine, browsing is instant, when you go to copy counting up the files still has a few sub-1 sec pauses, but copying is still ice-age slow. As a rough idea it's still sub-3MB/s.
This is a huge issue for me as I have all my data on the server and need to get i back in, ut every time I try to copy something I have to leave it for hours. As a good gauge, a 20GB pile of movies took about 5 hours to copy. According to my math it should have taken less than an hour. A 100MBit LAN connection should, in ideal circumstances, be shifting over 20GB of data an hour on a continuous copy operation. Mine barely manages 4-5GB.
I tried pinging the server and got a 0.2-0.3 ms response. I don't get any horrific packet loss (non at all in fact). Nothing has changed on the network since I backed up from Tiger. Again, I've been using the Mac Pro with this server and 10.4 for months copying to and from and it's been faultless.
Extremely frustrated. Hope someone can help!

After installation of Leopard I did have a lot of problems with reduced speed transferring files to and from other Macs on my network as well as to and from my Airport disk. All the way down to 0.5 MB/sec
Leopard sets AppleTalk to be active as default. Turn off AppleTalk in network setup and you will hopefully see a significant increase in speed on file transfers. I am back to 5-7 MB/sec to and from my Airport disk, which is okay.

Missing files when copying over network

I've had a good search for people with similar problems on Discussions, and there are a few mentions of similar occurences. Here's my summary though.
I have 2 Macs, and frequently transfer files from one to the other by sharing drives and using the Finder.
However, quite often, when transferring lots of files, they are sucessfully copied but do not show in Finder on the receiving machine. The files are there (using Terminal to explore the directory reveals the files in question), but Finder just doesn't acknowledge any existence of the "missing" files.
This problem can usually be cured by creating a new folder in one of the affected folders - this somehow kicks Finder into refreshing the folder's contents.
Removing the .DS_Store file(s) (again, via Terminal) in the copied folder also resolves this issue, leading me to believe that the problem lies with the .DS_Store files.
I cannot believe I am not the only user who frequently finds themselves having to do uneccesary Terminal work to reveal files which appear to be missing after copy over the network.
Is Apple aware of this problem? Does anyone else have any workarounds?

I don't think I have experienced that exact problem however, I am such a Unix geek, I typically do my in-network transfers between Mac machines using SCP at the shell prompt in Terminal.
Finder refresh on the other hand I have experienced before although I cannot provide a situation or example.
Usually if it needs a refresh, I believe all I ever do is navigate away from the folder, then back to it. Or if it is the Desktop in question, using Exposé to show it, a single click on an empty space there will make the newly copied items appear.

Finder freeze while copying over network

i have two mac on a network at home, both are now with 10.4.11 - but ever since i updated to this system version i am having a problem with the laptop. whenever i copy a file over the network from the desktop to the laptop, the laptop's finder freezes for the duration of the transfer - i can't open other apps, can't access anything else. the status bar of the copy doesn't change. if another app is open before the copy starts, it works fine. mouse works fine.
i can't figure out why this is happening... any clues?

Same problem here, I think: Finder hangs (beachball & Not Resopnding in activity Monitor) during file copy then comes back when copy finishes. Hang starts when I click in the finder to view another directory on the remote machine. When copy is done on PowerBook via Airport, Finder hangs. 100 Mb/s ethernet stutters but does not hang up, but 10Mb/s hangs up.
Same issue on this thread in Feb: http://discussions.apple.com/thread.jspa?messageID=6299419&#6299419
Some things I've tried to no avail:
Fixed Permissions.
New user does the same.
Reinstall 10.4.11.
Etehrnet 100Mb/s - No freeze, but finder still jerky.
Ethernet 10Mb/s and Airport 802.11g hang.
Other mac, wireless to laptop - ok.
Used file appleairports2.kext from 10.4.9, no help.
Deleted Finder.plist, no help.
Re-reinstall 10.4.11
Tried airport with no security settings
Trashed recent servers file.
When airport is faster, finder works slightly better, clearing freeze occasionally.
Activity monitor Finder not responding, sampling does not clear freeze.
I think it is interesting that Finder does better with higher data transfer rates. In fact, the problem is evident on an ethernet connection when I slow it down to 10 Mb/s, OK at 100. So it may be purely a Finder problem.
What I have not tried is going back to 10.4.9 nor a clean install of 10.4.11.
Has anyone figured this one out yet?
Thanks to UltraSoul for clear postings on this.

Faster copy over network? [Solved] Use Linux!

I'm wondering if there is a different way to copy files over a network that would be faster.
I'm running an updated version of ArchLinux, no gui, just command line.
I have samba working to see windows shares and have mounted a share.
I use "cp" to copy a file from the win98 share to my local harddrive. The file is about 670 megs. Every thing works great.
It takes 5 min 40 seconds to copy.
When I copy the same file using "copy" from a win98 computer it's done in just under 4 min.
Any suggestions?
smbmount //comp_lab_server/admin /mnt/winshare
cp /mnt/winshare/images/admin.zip /mnt/localdrive/admin.zip

Yes, not real clear, I wrote this real fast before running out the door...
jerem wrote:
* using cp : the copy uses the smbfs module in the kernel to retrieve the file from the win98 server.

generally faster... that's what I was looking for, but it just seams quite a bit slower
jerem wrote:
The two methods have different results because the copy goes through different processes, different layers, on different systems.
Using smbfs apparently involves some overhead(given your figures).
ok, that helps, I was just making sure I wasn't missing some other great tool that was known to copy files faster.

nope, same computers (dual booting), same disks..

Acrobat 9 Pro very slow open files over network in Windows 7

I have installed Acrobat 9 pro on my new PC. It's running Window 7 64bit. I use it for pre-press of high-resolution files for printing. Sometimes the file sizes run into the 100s of MB.The new PC has reasonably high specs, with 6Gb of RAM and a 2.8Ghz Quad core i7 CPU and gigabit networking.
Opening them when on the local hard disk is reasonably fast. For example a multi-page 400Mb file starts drawing the first page withing 3 seconds. But opening the same file when it's on the server of our gigibit network generates a very long pause. The application locks up and dispays a "not responding" message for 2-3 minutes. The bigger the file, the longer the pause. It doesn't completely crash -- eventually it starts to draw the pages and I can work as normal.
I used to have Acrobat 9 pro on my old XP PC which was a cheap low-end machine when bought 3 years ago. (has on-board shared RAM graphics card and only 1Gb of RAM). But what grieves me the most, is this slow old machine will open the same 400Mb file off the server so much faster than my expensive new machine. There is no lock up and it begins drawing the first page after only approx 5 seconds.
The problem doesn't seem to be simply related to slow network speed. I can copy the entire 400Mb file from the server to my hard disk in only 12 seconds. The old PC is actually slightly slower copying to/from the network. If the application was for some reason copying the entire file into memory or to a local cache, this should still only generate an extra 12 second delay -- not 3 whole minutes.
Adobe Reader 9 doesn't have the problem. I can open the 400Mb file off the network on either my new or old machine within seconds.
Acrobat 9 Pro doesn't have the problem on an old G5 mac either. It's somewhat slower than my old PC but will begin drawing the first page after a few seconds,
So what exactly is Acrobat doing for those 2-3 minutes?
I have already tried:
1. changing network ports/cables.
2. disabling anti-virus software
3. disabling "remote differential compression"
4. Patching Acrobat 9 to 9.2
5. Files located on Windows servers and Mac Xserves.
Not improvements from any of these.

I think I have isolated the source of this problem. It's the Pitstop Professional 9 plug in. I un-installed this, and everything opens quicker than greased lightning. I re-installed it and it's back to slowsville.
Unfortunately Pitstop is essential to my workflow.
Until recently I did my pre-press on a Mac G5 with Acrobat Pro 7 and Pitstop 6.5. I never had this problem with slow file opening. But it seems that the delays would occur when I used the plug-in with large complex files.. So it would open files as fast as you'd expect from an elderly machine. But starting to use Pitstop would result in a prolonged period of staring at a spinning beachball.
I wonder is there any way to stop the Pitstop plug-in from initializing until it is used? So the plug-in stays inert until you select the tool from from the menus.

Impdp over network: sometimes slow

Hello,
I've just made an experience, that impdp over network is sometimes slow and sometimes fast:
My configuration:
I have a "source" database (lets say A), with version 11.2.0.1, and two "destination" databases B (11.2.0.1) and C (11.2.0.3).
The data size is about 100 GB. Import from A into B needes about 4.5 hours, and import from A into C takes about 1.5 hours.
The data which is moved are identical. I've also checked the wait states, and we have found out, that database B makes a lot of log switches
during import, which is the reason, why database B is such slow. On database C there are almost no log switches.
B has log switches frequency about one in 2 seconds. C has aprox. 6 log switches in the first 30 minutes (during DATA load).
That database B has logswitches, and C not let me think about Direct Load versus External Table Load, which is described in the documentation.
But this seems different when using network_link: the trace of the DW process does not support this information (but should, as described in 552424.1).
I think, there are some bugs/features fixed/changed between 11.2.0.1 and 11.2.0.3 regarding load strategy over network_link.
There might be also a chance, that a initial parameter is different between B and C causing to different behavior, but
Does anyone have a similar observation? Does anyone know about this "change"?
Additionals:
The users have all the same grants, the data are exact equal (by FLASHBACK_TIME), remap_schema and remap_tablespace are used at both.
Ulrich

Hello,
Database A is in archive mode, B and C not.
The problem is in the data transfer, not at index generation.
For C, the data transfer is 30 min, Index generation is about 1h.
For B, the data transfer is about 200 min, Index generation in about 1h.
I have one new information: We have switched back after this to dumpfile transfer, and interesting: With dumpfile, the import is done with Direct Path.

Problem with permissions when copying files over network

This is my setup. Our design studio have several iMacs that the designers use for open projects, when they are finished I copy them over to a G4 which has a SATA raid in it which is used as a file-server for all closed jobs, photos and logos. The file-servers mount point was created using an app called 'Sharepoints'. The iMacs run 10.5.7 the G4 runs 10.4.11.
When I try and copy over a folder full of folders/files for a given project into the given clients folder. I keep getting the error, "the operation cannot be completed because you do not have sufficient privileges for "filename".
If I get info for the given file the owner, group and everyone have read & write access. The client folder on the file-server has the owner, group and everyone having read & write access. I can drag that file by itself over to the file-server and it will copy fine with out the error.
This is doing my head in, the quickest way around the problem is to archive the folder, copy it over and then un-archive it.
Can anyone shed any light on why this is happening and what I should to to fix the problem. Thanks

Playing footage over network - slow down after a while

Hi everybody, I have ProRes422 footage I work with stored on network. We bought a 12TB NAS and I found, that when I play the edited movie from timeline, it freezes after a while (2-5 minutes) - it seems to me there is some kind of network overload so that the data cannot be transferred fast enough to continue playback. I thought it is problem of the NAS, but I tried to read the footage from external HDD over network and the problem is the same. Would any of you have an idea how to fix this?
Thanks

For users like you who insist on ignoring the warnings and still want to buy cheap, I offer this alternative:
Buy Local Attached Storage, RAID 5, for each work station, a gigabit Ethernet switch, and CAT6 Ethernet cabling.
These days, you can buy 8TB of RAID 5 storage, including the RAID card, for less than $4,000US. The Ethernet6 switch is about $50US and the cabling is cheap.
Buy twice the storage as you think you need, then make file copies via the gigabit Ethernet network of all files on the storage on each computer onto the storage on the other computer. Now, you are maintaining a continuous back up of all data, which is a bonus benefit.
The real benefit, though, is speed. Modern RAID 5 storage systems achieve throughput in excess of 600 MB/sec, far more than 23 MB/sec.
Your investment in new equipment will be far less than buying a SAN.

Slow copy and install times with ARD 3.6.1

I have just this school year setup a new iMac lab with 23 clients and 1 admin iMac. All are 27 inch 3.2 Ghz. All run the latest Mac OS.
The network is running through a 100baseT Brocade switch. When copying files to all clients the transfer speed is really slow. I often need to copy over QuickTime movie files that students watch to learn steps for Photoshop and other applications. The file sizes can be well over 50Mb at times.
I used Migration Assistant to set up the Admin mac from a previous Mac. Could that be the cause?
What should take seconds is taking many minutes. I am frustrated and have asked the network admin's to help but the school is all PC except for my lab so they are manly PC guys. But they are trying to help.
Can anyone make some suggestions as to what may be going on?
I have requested a 1000baseT switch to see if that helps, but it will not be installed till next year sometime.
Thanks,
Ben

I believe this is bug with ARD that has yet to be fixed. If you copy the same file to just one computer using ARD it should be fast, but if you copy the same file to two computers or more in ARD it gets more than twice as slow. The more computers you try to do at once in ARD it gets magnitudes slower. For some reason ARD cannot handle multiple streams. It is so bad that even when working on multiple computers I still have to do them one at time if there is any copying involved. I can do 10 computers one a time via ARD so much faster than all 10 at once.
So give this a test, deploy your large file or application to all 23 systems and time how long it takes to get to 10% complete. Then stop it and have ARD send to just 1 computer. Do the math and you will see ARD ***** when it comes to copying anything to more than one system.
We are gigabit in our lab already and it did not help solve this bug.

Existing files on drive connected to latest Airport Extreme do not show up, however files copied over the air to the drive do. Any ideas?

I have the latest Airport Extreme with a Seagate drive connected. I copied files to the drive while it was connected to my MacBook Pro. The files do not show up when connected to the AE, but they appear when connected to the Macbook, Files copied over the network to the drive appear. The drive is formatted HFS+.

After playing with this for the last few days, I found a solution. Under the "Disks" tab in Airport Utility, the "Secure Shared Disks" drop down needs to be set to "With device password". Mine was set to "With acounts", which even after correct authentication, none of the files would appear.
Another interesting note: The files that I could see, the ones I copied over the network, do not appear now. I can copy over new files, and they show up, but the ones copied prior to changing the "Secure Shared Disks" option, do not.

Workaround for slow Bridge when network drive is inaccessible?

Hello all,
Hoping someone has some information regarding an issue I'm having with my workflow and Bridge. I have CS6 installed and am using the 64bit version of Bridge for file management. I work from 2 locations at the moment and have a portable drive that I take with me from place to place with my work files on it. In one location I can plug the drive directly into my system via USB, but in the other location (for various reasons) I have to plug it in elsewhere and access the drive through a network. This all works fine and I have no issues with getting to my files in general. Where I do get an issue however is when I start trying to add shorcuts to the drive within the "Favorites" menu in bridge.
The short of it is that as long as I have a shortcut to the networked drive in the Favorites menu, Bridge will run EXTREMELY slow when I am at the work location where I am accessing the drive directly. It appears that Bridge is trying to look for the networked drive on all the networked computers at that workplace every time I try to access a file or even use the menu system within Bridge (to right click a file for properties for example). I can alleviate the issue by removing the networked drive from my favorites or disconnecting form the internet (that one is not a practical option however), at which time Bridge stops trying to constantly look for the drive eveywhere and returns to normal speed.
This isn't a horrible issue for me, it just creaates a lot of repeat work of having to navigate to the network every time I open bridge again at the location where I access the drive remotely, or having to constantly re-add the networked drive back into the favorites every time... then having to remove it again before use at the other location and so on. Is there a way to adjust or change Bridge's behavior to basically tell it that if the specific drive isn't available after the first attempt to ignore it from then on unless I specfically click on the favorites link? Or in lieu of that, is there a way to have alternate "profiles" within Bridge that have seperate favorites etc. so that I can switch back and forth depending on the location I am at?
Like I said, not a horrible issue, but I really like having the quick, easy access to the drive that the favorite menu provides and would love to have a work around if one is possible. I realize that this setup is not common and so I might just have to deal, but if there is a super user solution or something I can tweak in a config file somewhere I would love to know! Thanks for the input and advice in advance!

Thanks for taking the time to respond guys! Yeah, I didn't think there would be any easy answer to this one. I actually have never had any issues running Bridge with any network I've been on with the exception of the lag when the network drive isn't present. Or to be more specific, severe lag when the networked drive is stored in favorites and then is absent in a situation where there is another different network of computers present. Don't know if it will help anyone who is trying to connet to a network drive etc. but all I do to get Bridge to "see" the network drive is navigate to the desired network drive or folder in Windows Explorer and then drag the drive or folder icon over from the Windows Explorer browser into my favorites area in Bridge. It drops the network link right into the favorites menu complete with a special network icon for the link. That has proven to be the fastest way for me to get a correct and functional connection to a network drive stored in Bridge. I was doing this with Bridge CS5 as well and it has always worked great for me.
For my network drive situation specifcally, I actually link to the entire drive as It's used solely for my design work. It's uniquely named with a title specific to me and my business so it definitely wouldn't be sharing a common name with any other drives or folders on another system on the network. I save the link to the network drive in my favorites and then I only ever have to click that to get to the root directory of the drive and navigate to whatever I need. Works great and super fast at the location where I need to use the network drive. Maybe I don't have hiccups like some because my computer has a reserved IP for that network tied to the MAC address of my computer so it is always the same IP every time.
The functionality I would like is actually very close in Bridge, with the only issue being that it insists on searching other computers on the network after every process it does if the network drive isn't present. The location I work at that doesn't use the network drive setup has 5 computers linked up to their network and so I guess it's scouring each of those every time I do any single thing in Bridge, looking for the long lost network drive lol! I have to confess this is strange behavior and really seems like a bug (albeit maybe a minor one due to the unusual workflow method) to me and Bridge is the only software I have that does this type of behavior. I can't really think of a good reason why you would need Bridge to look for a drive or folder in a location other than the one you have specified in the favorite path for it. I mean what if you have 2 copies of the same folder in different locations for backup purposes? You wouldn't want Bridge taking the initiative on it's own and accessing your backup folder without telling you, especially if there are legacy versions of a file you wish to retain in the backup location.
If anyone ends up having a solution for this I would love to hear it! Otherwise I'll just have to hope that Adobe eventually buffs up the network functionality of Bridge down the road and in the meantime add and remove the favorites path all the time. I would think smooth network functionality would be increasingly needful and important however. I mean Adobe even offers a cloud service version of their software... That implies to me that they are aware that more and more work will be done "in the cloud" and over networked scenarios. I have my fingers crossed! Thanks again for the info guys!

I'm buying a new Macbook Pro this week and am wondering what is the best way to copy over the software I have from my existing Macbook Pro to the new one? eg. Photoshop and Office etc. I no longer have the CDs.

I'm buying a new Macbook Pro this week and am wondering what is the best way to copy over the software I have from my existing Macbook Pro to the new one? eg. Photoshop and Office etc. I no longer have the CDs.

Ya know what I'm on a brand new MBP just about 24 hours old and you know whats been working amazingly for me. I have a 27inch iMac as well and i've just connected it to my network and been dragging files and apps across the network onto my new MBP. Its really working fast and its flawless. You could always do that option, Just go into sharing options and turn them on for both Macs. Then just click and drag. Of course they have to both be on the same network for this to be possible.
Look at my network.
Shared is what your looking at. I click on there see all my computers files and then drag the ones i want form its folder to my MBP folders. Hope that helps if your looking for a very simple way on a wireless network.

Very slow copy and rm speeds

I've seen other postings about slow copy processes upon upgrading to Snow Leopard. However, none of the replies seem to address the situations I am experiencing. First, copy times between my MacBook Pro (2 Ghz, 2GB, 100GBHD, 15" - the first MBP introduced), and external USB2 Lacie HD have become very slow (1 hour for 4-6 files totalling ~4GB). Curiously, sometimes the same size transfer occurs in 3-4 minutes. I recently upgraded to SL from Tiger, and the Tiger times were in the 3-4 minute envelop. The external HD is a 1TB Poulton Lacie, with over half the disc free. My MBP HD has about 20GB free, and only the Finder, mail, occaisionally xcode, and occaisionally a browser, (either Safari or Firefox) are running during the transfer. The same sometimes occurs with only the Finder and the activity monitor running. The USB is connected directly to the MBP. So, in summary, the ext HD is directly connected, half empty, there is room on the internal HD, and the memory is not particularly burdened with other processes. The activity monitor slows less than half the CPU capability being used.
Secondly, another problem occurs using the unix secure erase, rm -Pr. It is very slow since upgrading to SL from Tiger. The finder's secure erase is too slow to use.
Any thoughts about why on either? Right now, I'm wishing that I stayed with Tiger. Thanks.

I suggest looking at your logs in Console.app to see if anything unusual is happening during the long file copies.
The SMART status isn't that useful. If it says the drive is dead, the drive it dead. If it says the drive is "verified", the drive could still be dead. A good indicator of this is if file copies take an hour instead of 3 minutes.
Is this the original hard drive in that machine? If so, I'm surprised it has made it this long. Notebook hard drives typically start failing at three years of age. You might not notice it until you do a major reoriganization of your files' organization on the disk - such as installing a new operating system.
I compared Finder's secure erase with rm and they seem more or less equivalent.
I think your internal hard drive is just failing. That's all.

Photoshop CC OSX 10.9 - saving over network

Hi, I've done a couple of searches for this problem but havent found any similair situations.
I am having a problem with files which are 'dissapearing' when canceling a file from saving. For example - I am working on a large file and press 'save and close' but realise I don't need to save as the only change I have made since the previous save is something like turning a layer visibility on/off, so I press cancel. Then what I would of done is just close without saving, as I havent made any changes. However now the file has dissapeared.
System info:
Mac os X 10.9
Photoshop CC - latest update ( as of 19_3_14)
Saving to - HDD on a duplicate system over ethernet network.
I few tests I have done are-
Saving to desktop/internal HDD of workstation - File doesn't dissapear when cancelling a save.
Another computer in the same network on OS X 10.8 (PS CC) - File doesn't dissapear when cancelling a save.
(This makes me think it is a Photoshop CC/Mavericks issue.)
I've read that adobe does not support saving over a network, but I thought I would ask if anyone else has had/resolved this issue.
We have multiple workstations working in the same network folders, so saving files to desktop then copying over isn't a time effective option unfortunately.

Photoshop CC (internal version 14.2.1) does have a number of fixes that are better than Photoshop CS6 in regard to network saving. Be sure to choose Help -> Updates to get the latest version of Photoshop CC. If you are on Mac OS X, please be sure to at least be running 10.8.5 as there were also network save fixes at the OS level that will help customers.

Extremely slow Internet over Airport, good speed with Ethernet

I've been using an airport extreme router (802.11n) for a while and recently I've noticed an incredible slow Internet over wifi. When I do a speed test it shows numbers like 200 kbps and I have a 10 mbps cable Internet connection. When I connect the ethernet from the modem it's perfect speed. Obviously Airport is slowing down my Internet connection. I tried resetting the Airport by pressing the reset button at the back, and it worked perfectly for a while. But after a few days it got back to slow Internet. Anybody have any idea?

I don't know if this will help anyone else, but I came across some changes (purely by experimentation) that may help. I hope so, at least...
I opened the Airport Utility and I swapped channels. The default is channel 6, but every other WiFi router defaults to this channel, too. I changed my Airport Extreme to use channel 3 (as well as my Airport Express), and now things are back to what I would have expected for an 802.11g connection.
I will offer the suggestion that those of you with the same Internet slow-down observed on their iMac G5's try swapping channels. If you have an expanded WiFi home network vis-a-vis an Airport Express, be sure to update it first before you update your Airport Extreme.
Best wishes and good luck!
