AFP Browsing / Transfer Speed

We have a lot of remote workers connecting to our xserve through a domain name pointing to our network. I am wondering if there is anything we can do to improve the speed of browsing directories and transfer files? I don't know if it is the nature of how AFP works.
We are running more than AFP on our xserve. Are there other services that are known to compete heavily for priority? Also, we can turn discovery off, and possibly use workgroup manager to tell systems about the server. Would that keep the finder from having to do extra work locating things? I am not sure if that even matters. Especially since remote people connect with an Domain and IP. Does NAT translation have an affect?
Thanks for any help one can provide.

I noticed AFP is a lot faster then SMB. I also notice SMB on XP is slower then SMB on the mac. IF your server has dual Nic cards you can bind them together to form one nic and have 2GB uplink rather then 1 unless you need 2 IP Address?

How to increase AFP data transfer speed?

When I connect to our server from a WAN source outside of our facility the file data transfer rate is extremely slow. We just upgraded to a 10Mps fiber service and that has dematically increased our website data tranfer speed. I would like to find a way to access the file server from remote location and work, but the data transfer rate makes productivity impossible. I would appreciate hearing how other organizations are set-up and functioning with file transfer sizes at an average of 10 to 15 Mb.
Thanks,
Brian
OS10.6.8 Server,

If you don't have enough network bandwidth for your time requirements, you have little chance of success with the direct approach. Techniques such as file compression and such can only provide limited help. If you're transfering multiple copies of the files, then you can push one copy of the file to a hosted provider, and then serve additional copies from there.
As for your network, a ten million bits per second network connection is the speed of first-generation Ethernet. That Ethernet was a fast network, back in 1985. In the era of a one billion bits per second Gigabit Ethernet and increasingly commonly with the ten gigabit Ethernet links, a 10 Mb link is glacial.
A typical DSL network is asymmetric, meaning you'll have 10 Mb down (theoretically) and some fraction of that up. So you might not be getting that 10 Mb in the direction you're coppying files. And this is best case; various of the ISP network links around aren't providing their rated speeds.
AFP stinks on a network, and you're also opening up your file system to remote attackers.
As for WebDAV, read this. In addition to WebDAV, you can also try an sftp or other "simpler" copy command as a test, and see what you get for that. (sftp is also encrypted, which has benefits, though the encryption also requires more processing time.)
But beyond techniques such as data compression (and which may or may not be an option here) or incremental or "delta" changes to the data (which probably isn't an option here) or working locally and batching over the changes, there are few good ways to contend with a too-slow-for-your-needs link.

WRT350N - Transfer speed via Storage link

I have always been curious what the transfer speed others get while using
a USB 2.0 hard drives on their WRT350N.
Obviously there is going to be a drop in transfer speed using storage link but 2-3 Megabyte seems slower then I would expect. I don't thnk I have ever seen much about 3MB.
I see the same performance wirelessly (connected at 270mb) and hardwired into the gig ethernet port.
Just wanted to get some other peoples results.

It was on both systems. However, I did get it working. Not the way I liked, but it works. What I expected to see was the device hung off the network. That is like another computer. This *is* happening, but where I was confused was the access to it. On other shared resources I can open it at will with no special access rights needed. I'm talking about printers and files on other computers on the network. It turned out to access the Storage Link I had to actually provide a USER ID and PASSWORD before I could use it. Why I couldn't get access before was I had HTTP:\\192.168.1.1 already open in my browser so any other attempts via the web browser used the existing connection. Not until I saw a forum message that said use START=>RUN and enter the IP address or UNC name was I able to connect to it. Since I now know this, a simple bat file with some NET USE's should fix the problem of getting access. Compounding my problem is how I've chosen to manage the network and shares. I use Network Magic, and it can NOT see the Storage Link at all. Anyway, I now know how to access the Storage Link. I was using a Flash drive for testing. I'll next put a USB External drive on and try that out. My ultimate try will be a USB hub and 4 external drives and hopefully I'll have access to all 4 drives to all computers. Irv S.

Transfer speed of USB vs Gigaport attached drive WRT610N

I know this is a loaded question but here goes: Assumptions: eqivalent drive specs but one is connected to the USB port of a 610N and the other is connected to the gigaport of the 610N which drive should have the fastest throughput and approximately by what % margin?
The reason that I am asking this question is that I did a backup of about 40GB to a Seagate drive attached to the USB port and it TOOK FOR EVER!!!!!!!!!!!!!!
I have a gig capable drive on order and am praying that the performance will be much better than the USB drive.

What is the speed you are getting from the USB Port..?
I think you need to make some changes on your Wireless router, so the Download and upload speed improves.
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 Leave username blank & in password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab -
This settings are for 2.4GHz.
-Here select manual configuration...Wireless Network mode should be mixed...
-Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WEP, Encryption should be 64 bits.Leave the passphrase blank, don't type in anything...
Under WEP Key 1 type in any 10 numbers please(numbers only and no letters eg: your 10 digit phone number) and click on save settings...
Please make a note of WEP Key 1 as this is the Security Key for the Wireless Network...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect, and after this try Downloading and Uploading on your Storage Drive and check whats the speed you are getting
Same goes for your 5GHz Wireless Network.
Wireless Network mode should be mixed...
-Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network.
Set the Radio Band to Wide-40MHz and change the Wide channel to159 and Standard Channel to 161-5.805GHz...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA, For Encryption, select AES...For Passphrase input your desired WPA Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone and remember the key.
NOTE : Passphrase should be more that 8 characters...
Try and see how is the data transfer speed.

Slow transfer speeds between two macs

The general setup: an iMac Intel 20" and an iBook G4 1,2GHz connected via an Airport Express (newest edition), both computers running 10.4.7.
When trying to transfer files via AFP between the two on my local network, I get "tremendous" speeds of about 0.5-1 MB/sec. Why is this so incredibly slow? Is it because of encryption or something similar? I can download off the internet with greater speed than that!

i have exactly the same problem , using a macbook black g1 . slow network speeds and flakey internet . these were ok when I first got the machine . but are now slow as . using the network view of menumeters I see that if i try and shift files from my mac mini they are incredibly slow with menumeters show 0.0kb/s for seconds at a time .
to trouble shoot this problem I used another friends macbook configured with exactly the same settings on this network and the transfer speeds were as they should be which was about 1.5-2.5 megs/sec .
so i figure there is some preference corrupted but which one ?
I have experienced several crashes recently . because of the overheating bug I have the fix applied to my machine and the firmware update . Maybe the network preference got corrupted at that point .
any tips as to which preference to delete would be appreciated .

Ethernet transfer speeds??

Hi, when transfer files between my iMac(early 2013) and my Mac mini(late 2012, running windows 7 in bootcamp) via my wired network, I'm only able to get speeds around 20-25MB/sec, thou I'm using a gigabit wired network, with D Link gigabit switch and cat 5e cable....
Could someone please guide me, what am I doing wrong, because I should be able to have transfer speeds around 125MB/sec(theoretically)
kindly
Jan

Just came across this, maybe I should wait for the new OSX maverick.......
"Network File Systems
OS X includes a broad set of network file services—SMB, AFP, and NFS—for sharing files between Mac and PC.
SMB2
SMB2 is the new default protocol for sharing files in OS X Mavericks. SMB2 is superfast, increases security, and improves Windows compatibility.
• Efficient. SMB2 features Resource compounding, allowing multiple requests to be sent in a single request. In addition, SMB2 can use large reads and writes to make better use of faster networks as well as large MTU support for blazing speeds on 10 Gigabit Ethernet. It aggressively caches file and folder properties and uses opportu- nistic locking to enable better caching of data. It’s even more reliable, thanks to the ability to transparently reconnect to servers in the event of a temporary disconnect.
• Secure. SMB2 supports Extended Authentication Security using Kerberos and NTLMv2.
• Compatible. SMB2 is automatically used to share files between two Mac computers running OS X Mavericks, or when a Windows client running Vista, Windows 7, or Windows 8 connects to your Mac. OS X Mavericks maintains support for AFP and SMB network file-sharing protocols, automatically selecting the appropriate protocol as needed."

10.9.2/3.1.1 server terrible transfer speed!

Hi,
Just installed a brand new mini with 16GB mem and SSD disk. The transferspeeds, afp or smb are absolutly terrible. Anyone?

I'm going to guess that there's some sort of a network involved here, and that you've tested local transfers and those run at (much) faster speeds.
Slower network transfer speeds are usually some combination of WiFi interference, or problems with the wiring or the switch (some patch cables can really hinder performance), or a misconfigured speed or duplex setting with a wired network connection, or a slow network link somewhere. Older 100 megabit ethernet (MbE) switches are slow choices for storage access, and gigabit ethernet (GbE) networking is preferred here.
Start testing some different configurations, and see if you can isolate the trigger.

External hard drive, error -36, corrupt files and slow transfer speeds

This is a long post but stay with me.
I've got an external 250GB Lacie drive connected to my 24" Intel iMac via Firewire 800. I have approximately 80GB worth of files (including my iPhoto library) on the Lacie that I'm trying to move over to my iMac but have run into some frustrating problems.
Overall, transfer speeds are erratic – fine at times and SUPER SLOW (5 minutes to transfer a 3MB file) at other times. At first I was transferring entire folders, but after always getting errors (error -36 to be exact), I was having to transfer individual files. This works fine as long as the files aren't too big (which makes the transfer speeds SUPER SLOW) and not corrupt (which gets me an error -36). Is my Lacie crashing on me? Is there any hope?
Here's what I've done to try and salvage my sanity with no resolve to my problems (not exactly in this order):
1) Ran Disk Utility to repair Lacie. Everything came back OK
2) Ran Disk Warrior on Lacie. Found a handful of bad items that Disk Warrior was able to repair. Had Disk Warrior replace the old directory of the Lacie with the new directory.
3) Ran Drive Genius: Raired and Rebuilt the directory, did an Integrity Check (came back OK), attempted to Defrag but could not because of errors to the drive, did a Scan for bad blocks (which after running for 3 days! it was only 20% complete and had found over 150 bad blocks, at which point I quit to try something else)
4) Checked that my Firewire cable was properly connected and replaced the older one I was using with a brand new one.
5) Disconnected all peripherals except for keyboard, mouse and Lacie.
6) And at times, even viewing a file on the Lacie has caused my Finder to crash, requiring a restart of my iMac.
I'm sure I've left something off I've tried but you get the idea.
I've read that maybe I can transfer my files using Terminal. Yes/No? Does this bypass any corruption the files may have?
What about creating a second partition on the Lacie and moving files over to the second partition? Does this solve anything? I don't know anything about partitioning so maybe I'm talking crazy.
I've also read that iPhoto tends to corrupt files which makes me hate iPhoto, and myself for not backing up.
And I've read a lot about error -36's and none of it sounds good so I'm just hoping that someone might have other suggestions for me to try and save my files (especially my iPhoto files which include baby pictures that if I lose, my wife will kill me).
So if anyone has any ideas, let me know. Please. I'll try anything.

Hi Aaron Thompson-
I am fairly certain you have a bad power supply brick to the LaCie drive. This is a hard problem to troubleshoot as generally when the bricks go bad they do so slowly and the drive appears to power up and stuff but it just doesn't work.
If the drive is under warranty LaCie will replace the brick at no charge. Otherwise they sell them for around $20US on their website.

Problems with Photoshop performance and data transfer speed on iMac

Two months ago, I started noticing slow performances using Photoshop (above all using clone stamp tool) on my 27" iMac (late 2012). I did the AHT and I found that 8GB of 32GB RAM were broken.
I removed them but the problem didn't disappered, I also noticed that data transfer speed (both copy and paste from/to internal HD and from CF card/external HD) was really slow.
I tried many solutions suggested by Apple support, none of them worked out. At the end, I tried uninstalling and re-installing Photoshop: no more problems!!!
10 days ago, I received a new 8GB RAM module and so I installed it back... suddenly, the problem came back, I tried re-installing again Photoshop but the problem, this time, still persist!
Does anyone had the same experience? All other CC programs work well (LR, AE, Premiere...)

yes, it does!
what seems to be very strange to me is how data trasnfer speed could be affected!
(just to say, I've already tried reset of SMC and PRAM, I've tried with different accounts and I've also re-installed the OS, next step would be formatting the disk and installing the OS from zero)

Very slow network directory listing - but fast data transfer speed once listed?

Hello,
I have really tried to sort this myself before opening up to the community, however I have run out of ideas, and hope someone can offer the magic solution I have missed.
I am currently using the 3.4ghz i7 iMac on a 1GB LAN, running OSX10.7.2 - connecting to a Windows Server 2008 (Running Release 2) over ethernet.
If i go to a network directory that i haven't recently accessed it can take up to 60 seconds to show the contents of that directory. Once i have accessed that folder, if i come out of it and go back in it will be instant again - but the first time it lists the directory it looks like i have opened an empty folder - which after anything from 10seconds to 1 minute will suddenly show the files that are there.
Internet connectivity is fast through the network, and file transfers across the LAN are fast. (showing as approx 300mb per second) I can play and edit HD content across the network with no slowdown so I am confident that this issue is not related to the network speed itself, and is more to do with a setting on this mac.
Symptoms are very similar to this post: https://discussions.apple.com/message/12245148?messageID=12245148&amp%3b#1224514 8 - however i understand that in OSX Lion - SMB was removed - so i cannot find this file to edit.
I have tried bypassing additional hubs in the network by wiring direct cables to the switch that is connected to the file server, this made no difference.
I have also tried disconnecting the ethernet cable, and running over wifi. This fixes the listing problem, but when editing HD content over a network drive, this connection is not fast enough to carry the data without interruption (some projects are linked to up to 900gb of hd video content!)
Using ethernet, I have tried DHCP, DHCP with manual address, and manual mode. All reproduce this problem. i have tried using the windows workgroup, and tried without it.
I have also followed this suggestion: https://discussions.apple.com/thread/2134936?threadID=2134936&tstart=45 and used OpenDNS. this did not fix the issue.
For argument sake, I have also just tested a Macbook Pro running Snow Leopard to see if it was OS related. This reproduces the exact same problem, near instant directory listing on the wifi, a long and arduous wait on ethernet.
I cannot work out why directory listing is instant over wifi, but not over ethernet on 2 different macs, running 2 different versions of OSX. I also do not understand why if the network is having trouble listing the directories - the data transfer speed is 300mbps when i copy files across the wired network from the file server to the mac.
Does anyone have any other ideas as to what could be the problem here? We are about to start work on a very large project, where the content we are editing is spread out across around 200 different network folders (different shoots captured over the past 2 years). We really don't have the time to wait 60 seconds each time we need to access one of those directories to look for a file, and I am very close to pulling all my hair out!
I really look forward to hearing from anyone who can offer any insight.

If you are suspecting that the Windows update had something to do with your LAN going slow, then try the following:
1. Look for updates for your clients LAN NIC driver; or
2. Un-install the updates.

Very slow transfer speeds with external hard drives through Firewire and US

Hi All,
My external drives transfer very slowly on my MacPro. I've been searching for answers and have turned up very little. Apple support suggested I post my issue here. Just to make a note, I measured my disk speeds with both AJA System Test and copying files between drives and reading the Disk Activity in Activity Monitor.
I have 3 external drives, all MyBook Premium or Professional, 1x 500GB, 1x 1TB and 2x 1TB in RAID 0. I had them on Firewire 400 and the RAID 0 2TB one on Firewire 800. My transfers on FW were all around 24MB/sec on all drives (much less than what I should be getting with FW400). I then read somewhere that the FW bus on the MacPro uses the slowest speed connected for all FW connections. So I unplugged everything but the FW800 Raid 0 drive and my transfer rate jumped to 40-60MB/sec. This is much better, but still about half or so of what I expect it should be producing from an external RAID 0 setup.
To keep my FW800 backup drive faster, I've plugged the other two into USB2.0. The transfer speeds on both drives are now hideous, around 10-15MB/sec. This is so slow, but I'm not sure what to try to fix my speeds.
The HD's in the external drives are all 7200rpm, and all should be transferring at a higher rate. Do you have any suggestions or ideas? Ideally I'd like to get everything transferring at rates they should be transferring at, but I'll settle with my current FW800 speed of 40-60MB/sec if I can get my other two drives transferring at a non-snail pace.
Is this a common issue? I can't believe I'm the only one plugging multiple external hard drives into their Mac Pro. I hope someone has a fix or solution for this. I'm all ears!
Thanks in advance.

Hi Kappy, thanks for the information.
So I rejigged my setup a tad. My RAID 0 is still FW800, the second drive is back on FW400 on the back port, and the third is USB 2.0 on the back as well.
It's interesting to note that I saw the FW800 taking a bandwidth hit if the FW400 drives was being read/written to. For example, if I was averaging 50-60MB/sec on the FW800 drives and copy something large to the FW400 drive, each drive averages out to about 30/MB second, roughly half the FW800 speed I was getting. The USB while the slowest didn't cause any slowness on the FW drives.
Here are my Xbench results. These results are from each drive being benchmarked individually with no other drives being tested at the same time.

External firewire hard drive reverts to slower transfer speeds

This is the strangest hardware problem I've come across. I'm running a unibody mbp (June 2009) with an external WD 2.0TB Caviar Green drive mounted in a firewire 800 enclosure made by icydock.
Lately, I've noticed that after an unknown amount of uptime, the speed of file transfers to the WD external drive slows down dramatically. I figured this out by watching my time machine transfers take a bit longer after awhile, and I verified this using aja system test and speedutilities.
When I boot my mbp in the morning, file transfers and time machine backups to the external WD transfer at a rate of about 67-75MB/s. This is the speed the drive should always be working at since it's connected via firewire 800. Aja speedtest verifies the speed is as it should be as well.
Then, after a couple hours of using my mbp, or even later in the day, I'll transfer a file to the external WD or run a time machine backup and find that the transfer will only run at a max of 29-35MB/s. This is exactly half the speed the transfer should be going at. Subsequent transfers stay at this slower rate no matter what I do.
However, I've been able to fix this problem by unmounting and remounting the external WD or restarting my mbp. After doing either of these actions, the WD external goes back to contant transfers at 75-80Mbs. So something is happening where the longer the mbp is running, or after some sort of disk activity, the external WD reverts to a slower transfer speed (closer to FW400). I can't isolate whether it's an issue on the mac os side or the hard drive or the hard drive enclosure because I can make the hard drive go back to optimal speed again merely by unmounting and remounting it. This works consistently until a few hours later when the drive begins to handle transfers at half speed again.
I run hourly time machine backups to the drive. The time machine backups can't be the culprit because the drive remains running at optimal speed after the backups (verified with aja system test and speed utilities)
Any possible ideas as to why the drive cuts down to half its optimal transfer rate after a bit of time? I can't figure out the cause of this, and the consistency of the drop leads me to think this is an issue with the power management on the drive since it reverts to full fw800 speed when I umount and remount the drive or restart my computer. Could this be an OSX issue where for some reason the system isn't negotiating the fastest speed?
Any help appreciated.

From the SoftRAID manual:
Fire hubs and disk drives. FireWire hubs are notorious for introducing errors and instability onto the bus.
Make sure that all of your consumer electronic devices (iSight, cameras, scanners) are connected to a separate FW bus. These devices are not built to the same standards as storage devices and known for introducing errors onto a FW bus.
Cables. While most cables work fine with a single device, many cables will introduce errors when 2 or more disks are connected to the bus.

Output can be to any drive or partition. When you lauch iMovie it asks where to store your project.
I just bought a camera, and curious myself to see if I can take 10 minute clips and use iMovie/iDVD so that it will auto-play. I may end up buying Pogue's "iMovie Missing Manual" or something.

How do I fix the slow transfer speed over USB on my 24" iMac?

I am backing up/cloning with SuperDuper, and running Lion. The displayed transfer speed never gets past about 20mb per second. Painfully slow.... Any suggestions?

Actually that's pretty good for USB. USB is slow - there is nothing you can do about it. Firewire always has been faster. Personally, I only use external Firewire drives for cloning or backing up. Even then, if it's a fresh clone, it'll take moe than an hour for 160 GB.
So, I schedule it when I have other things to do and walk away until it's done.

Transfer speed and other minor bits

First off - I love my iPod (40g Colour) and despite my regular bouts of impatience when updated, loading etc I am very happy with the thing. I even bought my wife a shuffle and she likes that for when she's at the gym. I found the software/hardware to be very forgiving.
However I thought I'd post a query to see if anybody had any ideas on my minor problems.
1) When we loaded my wife's shuffle for he first time we had problems with the USB 2 convection. PC keeps saying "this item can run faster connect to a USB2 ....." but it is connected to a USB 2 socket. Now everytime I attach either iPod the same warning comes on (except if I connect before starting!). I know its a USB 2 because a new board was fitted a while ago and my 40g will synch and charge on the connection.
2) Slow transfer. I recently loaded iTunes 5.0 which didn't work for me (see 3). So I wiped it and loaded a copy of 4.9 (thanks to filehippo). Im up and running again but had to re-synch my iPod to iTunes. The tranfer rate is about 500 tracks per hour so to do the 8500 that my iPod takes needs 17 hours. When its done I should'nt need to do it agin for a while but could I speed things up a bit?
3)Should I go to iTunes 5.0.1? 5.0 loaded on my PC fine without all teh problems that have filled these oages recently but when in 5.0 I connected either iPod (shuffle or 40G I got an error somthing like "Ipod not recognised re-intall iTunes". I know some other people had a similar problem. iTunes 4.9 is working fine but is it safe for me to try 5.0.1 yet?
Sorry to go on a bit but I know from watching these forums recently there are some very knowledgeable and helpful people out there so I hope you don't mind my request.

I've had some news - most of it good. I got fed up with the transfer speed so I took my box into my local store to get it checked out. No visible fault on my USB 2.0! I know it happens but they couldn't replicate it so I went home. Plugged all my stuff in except USB devices. Plugged in my iPod and it worked. I was now thinking about power requirements etc. Plugged in my USB modem and the iPod still updated at USB 2.0 speed. Next I tried my wife's shuffle - so far so good. I then plugged everything in and the iPod defaulted back to USB 1.1!
Tried the shuffle in the spare USB2.0 socket and it worked. Plugged my iPod in and that worked - Now I knew what the problem was - I only have 3 USB 2.0 sockets (5 USB1.1)and two had faulted.
Next step will be a new card with a fire wire socket! Happy Days - although I still cant get an extension cord to work with my iPod.
While I was on a roll I took the bull by the horns and loaded iTunes 6.0. Works like a dream although it is a bit slower than 4.9 - probably considerably bigger but it works!!
My turn to be the lucky one this week!!! Maybe your turn next.
