Slow Network transfer

I've just added a second Time Capsule to my home network as my first one is now pretty full. Its extended my network fine and I've renamed the TimeCapsule fine. I left my Macbook pro to drop a 170Gb TimeMachine backup onto the new Time Capsule overnight. And it completed in 7 ish hours. So I know the access is ok.
I have a number of files I don't back up as part of Time Machine (iso images) and VMWare images of my dev PCs. I was planning on copying these over onto the shared storage on the Time Capsule but the file transfer rate is shockingly slow, even for a single file. Just starting the copy of a single file (they are pretty big at a couple of Gb each) takes a couple of minutes and stopping it takes a good 5 minutes to close the progress dialog.
A single 0.7Gb file was listed as taking 39 hours. Now I'm not sure what the data rate is but its obviously pretty slow. This is all via a wired 10Gb connection using a 3Com switch as the hub.
Now copying the same file from the same Mac to the old Time Capsule completes in under a minute. So what have I done wrong to end up with this rather odd situation? Has anyone got any pointers as to what I might look at or poke/prod to sort this out?
many thanks
Steve

That is slow if that is over 10GB ethernet. The TC should do around 60GB/hr for backup.. so something isn't right even with what is apparently ok.
A single 0.7Gb file was listed as taking 39 hours.
That is very bad.
I know it is a pain.. but I want you to pull the New TC out of the network.
Plug it directly into the computer by ethernet.
Do a factory reset on it. Very little else.. you are doing a file copy in full isolation from the network.
Make sure you are copying the file to new directory you create under the root..
Tell us the speed of transfer. (Also check that ethernet connected at gigabit.. you will see connect speed in network preferences or ifconfig in a terminal) And you can use activity monitor to check the file transfer speed.
Super slow.. take the TC back.. it is faulty. There seems to be a lot of it going around.

Very slow network transfer (AFP, thunderbolt, nas, gigabit, lan, lion)

Hi,
When copying large files (100GB) from my macbook air to my Qnap NAS the transfer is very slow (100kB/s). It becomes immediately much faster (10MB/s) when I lock my session.
The MBA is connected via the gigabit port of the thundrbold display and a gigabit switch to the gigabit port of the NAS.
There is negligible other network activity shown when monitoring NAS or MBA bandwith usage.
So what can limit bandwith of a mac while in unlocked session?
Is the a bug in thunderbolt display dramtically deminishing bandwith when used? Bandwitdth is already high when locked and display shows login screen. It does not need to fall asleep.
Thx

I want to thank you for your help but I think I have to give up. I've been trying for days to get the MBP just to recognise the NFS share. I've tried adding a server in Finder with no luck. I tried Directory Utility with full R/W access setup on NAS, then tried accessing root NAS folder, then the specific share folders, then with specific user enabled on the specific share folders but whatever I try I get nothing. I've changed my local username and password and UID on the Mac to exactly the same one I use for my NAS but it still won't find it and none of the command line options that people suggest do anything at all. I've tried SMB and AFP but they're both sluggish and nowhere near the performance of XP on the same hardware. For an OS that supposedly 'Just Works' I've had a very complicated, tedious and fruitless experience (pun intended). Maybe it's just me because others seem to report no problems accessing their NFS shares or transferring at high speeds with AFP or even SMB but I've had no luck whatsoever. Very frustrating indeed.
Again, sincere thanks for your time and I'll tag the post as answered because for all intents and purposes you answered my question very well. Unfortunately, this Mac just doesn't like me and I don't think I'll be spending money on one anytime soon.

[solved] Intel 5300 slow network transfer speed

Heya,
I'm having trouble with my WiFi card Intel 5300 AGN and i hope you can help me.
It's the transfer speed in linux that bugs me. While I get 9 MB/s in Windows I can't for the life of me get more than 2.5 MB/s transfer rate in linux. And this is only if I use NFS4 and turn off the wifi power saving feature. Samba/CIFS gives me transfer speeds of no more than 0.4 MB/s.
The problem has to be somewhere in my linux software/configuration. But where?
I don't have much experience with WiFi configuration in Linux so mine should be pretty vanilla. No manual change of frequencies, channels and the likes. I simply use netcfg to connect and sometimes iwconfig to toggle the power saving feature.
Here's what iwconfig shows me right now while copying a big file:
wlan0 IEEE 802.11abgn ESSID:"bett"
Mode:Managed Frequency:2.412 GHz Access Point: 00:14:D1:C7:43:C4
Bit Rate=243 Mb/s Tx-Power=15 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=61/70 Signal level=-49 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:11922 Invalid misc:2 Missed beacon:0
As you can see, power management is disabled. The link quality is very good and the bit rate is at 243 Mbps (which should give me about 15 MBps right?). Yet the transfer rate is only 2 MBps, sometimes dropping as low as 0.7 MBps, sometimes spiking to 4.5 MBps for a second or two.
What can I do to improve my network speed?
Any help is greatly appreciated.
Regards,
demian

Thanks for the reply zvxy.
I'm running the most current from [core], version 2.6.37.5-1.
Disabling the N mode improved transfer rates for CIFS/SMB shares. They are the same as with NFS now which is around 2.5 MB/s. Transfer speed for NFS stayed the same.
I'll try the kernel from [testing] and report back later.
// I've tested 2.6.38.2-1 a little bit now and as long as i don't disable wireless N i get transfer rates of up to 12 MB/s with NFS4. That's more than enough for me and i hope it stays that way. The downside is that transfer rate for CIFS is only 1 MB/s.
If i disable wireless n mode NFS transfer rates drop to ~2.8 MB/s while CIFS transfer rates go up to ~2.4 MB/s.
Guess I'll just have to stick with NFS (not that i don't mind but it's already thrown me some "stale" error messages with the new kernel ... i can't seem to catch a break ).
I'll consider this issue solved. Thanks!

Slower Network Transfer Speeds with .7

Since upgrading to .7, I've noticed slow transfer speeds. For example, when transferring one large file, I get 11MB/sec on average. When transferring a bunch of smaller files, I get about 1 - 1.5MB/sec. I remember is being faster in .6
This is transferring files from my Mac Pro to my Time Capsule, using Gigabit Ethernet.
Can someone let me know what speeds you are getting when transffering a large file from a Mac Pro to a TC and also a bunch of small files from a Mac Pro to a Time Capsule. (or any NAS drive)
I used Activity Monitor to test the speeds. Thanks.

Does your PC have a FireWire port? you can use IP over FireWire for better throughput than the wired ethernet.
You can't use link aggregation in this case since it requires multiple interfaces of the same type (e.g. two gigabit ethernet cards), but you cannot mix media such as AirPort and Ethernet.
The alternative would be to install a gigabit ethernet card in your PC. You'd at least then get gigabit ethernet speed between the two devices which is also a step up.

Slow network transfer on 10.5.8

Hello we have about a dozen machines running 10.5.8 and we have one windows file server running Grouplogic Extreme Z IP. The connection type is AFP. On one of the machines, although it appears to work well, it tranfers files very slow from the server. It takes 5 minutes to transfer a 2mb file. The machine is a dual processor Mac Pro with Gig ethernet. All the other machines work perfectly and transfer files very fast.
When I transfer files with SMB from another windows server machine, the transfer is normal. I would love to think its the server but the other 11 machines work fine and they are all same hardware and software. All machines are joined to our Active Directory system.
I tried almost all the troubleshooting I know, there are no errors on the switch, no dropped packets. Verified with Netowk Utility. I tried to unbing and rebing the machine to AD.
Any help would be appreciated.
Thanks
Aristotle Zoulas

That's correct the backup drive has 2 partitions one for the MBP and one for the powermac. I thought of that also, the drive is brand new and when the problem started I repartitioned the drive and switched the MBP and the PM partitions with no effect.

Windows Server 2008 R2 Slow LAN Transfer (Receive)

Using Windows 7 Ultimate and Windows Server 2008 R2
Two machines, connected via 1GB 1000base-T LAN, with a 1Gb switch between... and yes, I've tried swapping cables and ports. Server has two RAID5's, a 6 platter and an 8 platter. Workstation has two RAID5's, a 3 SSD and a 4 platter. Both sides using Intel
CPU's and a RealTek 8100C chipset Gb LAN, same LAN drivers.
Using Windows Explorer to COPY a 20GB file:
Server Disk1 to Server Disk 2: >250MB/s (Server disk I/O isn't an issue).
Server Disk2 to Server Disk 1: >250MB/s (Server disk I/O isn't an issue).
Workstation Disk1 to Disk2: >150MB/s (Workstation disk I/O isn't an issue).
Workstation Disk2 to Disk1: >150MB/s (Workstation disk I/O isn't an issue).
Server Disk1 to Workstation Disk2: 91MB/s (near 100% LAN utilization).
All looks good so far:
Workstation Disk2 to Server Disk2: 25MB/s declining to 17MB/s; occasionally as low as 9MB/s.
Some of the changes listed above appeared to work for a few moments. I've seen as high as 90MB/s for a few seconds, but it declines rapidly under 30MB/s... so no fix that has lasted.
It appears there is something in Windows 7 that prevents fast transmits; or something in Windows Server 2008 that blocks fast receives. I have set the server-side receive training to disabled, normal, highlyrestricted, and experimental and the Win7 side
to off, normal, and highlyrestricted in various combinations. Again, nothing concrete to report as an improvement.
What would the MS Gurus suggest I do with NetMonitor as far as capturing something worth their time to diagnose?

I've tried disabling auto tuning on the clients with no appreciable effect. The throttling feature however appears to have had an effect - changing the setting from default 10 to 70 has slowed the transfer from 20MB/s down to about an initial 6MB/s that
has slowed even further, and is now at 3.2MB/s (3% network utilization according to Resource Monitor at both ends of the wire - WS2008R2 and W7).
Question: What does the 10 (0x0a and 70 (0x46) represent: Mbps on the LAN, or 10% and 70% reserved, or?
I'll try the "off" setting of all FF's and add to this.
In any case, having a backup server that can't be utilized due to client "entertainment media" issues is a little painful... there should be a straightforward and published method to set the network to "normal".
UPDATE:
I've tried settings of 0, 10, 70, and FFFFFFFF. 10 might have been best, but only marginally better than 70. Range of time to copy was under 7 minutes to over 8 minutes. Very small difference.
But I also tried this using Windows Explorer and a Dataset of one folder containing 12.5GB of miscellaneous folders and files - and was surprised.
- Dataset is at \\WIN7\Dx\ = = Client physical RAID5 drive D:\Dataset
On WIN7 Client: Share drive D with Everyone as Dx
On WSvr Server: Share drive D with Everyone as Dx
On WIN7 Client: Map \\WSvr\Dx to Z:
On WSvr Server: Map \\WIN7\Dx to Z:
On WIN7 Client, using Windows Explorer:
-- Copy Dataset from Local Drive D: to Network Drive Z:
-- Took about 8 minutes, with 20% network utilization.
On WSvr (2008 R2 Server), using Windows Explorer:
-- Copy Dataset from Network Drive Z: to Local Drive D:
-- Took about 3 minutes, and 70% network utilization.
Why does running the copy from the server allow better network utilization and net throughput?
UPDATE2:
I am NOT using HOMEGROUP; I have a dedicated workgroup network the client is a member of, and the server is a DC. I'll eventually try joining the client to the domain and see if that changes anything, but doubt it will so haven't taken the time yet.

Slow Network Speed with MacPro

I just received 4 MacPro's with the dual quad processors. I have configured 3 for our workplace and have moved them into production. We are experiencing very slow network speeds, a test file on our server of 100mb takes 2 minutes 20 seconds to copy to the desktop. I have manually set the ethernet port to 100baseT with full duplo. The old machine is running the same OS 10.4.10, and only takes 12 seconds to copy the file. I should mention that we use DAVE to connect to our servers, both machines are running the same version of DAVE, and using a third machine I connected to both drops and the file copied in 12 sec, showing that the network is physically OK. The only difference between the two machines is that one is the intel version? Can anyone offer any thing to try?
Thanks

I am 99% sure someone else had 'slow transfer' in another thread.
Sometimes a router needs firmware update to be compatible, or upgrade the cables to cat6e, or look for a new router or switch which helped my own setup. Just look for one that says that it is "Vista compatible" actually.

Huge data on slow network

Hi All!!!
I have a client which connect to the database through slow network (2Mbit/s) with slow response time:
PING (10.6.0.5) from 10.1.9.24 : 56(84) bytes of data.
64 bytes from (10.6.0.5): icmp_seq=1 ttl=124 time=115 ms
64 bytes from (10.6.0.5): icmp_seq=6 ttl=124 time=109 ms
64 bytes from (10.6.0.5): icmp_seq=7 ttl=124 time=108 ms
Once per day client exec sql query which take 15Meg of data from database.
It's take a lot of time, much more if I transfer this data through FTP.
Why it's happend?
May be server can compress data before transfer?
Help me please.

Contact the carrier.

Slow file transfer - ethernet + firewire issue?

Here's the setup -
Win98PC > ethernet (direct cable connection) > iMac G5 > Lacie d2 FW drive
Connection (100BaseT) works, logins work fine, browsing folders & files is fine. But when I transfer files from the WinPC to the Lacie drive through the iMac G5 it is unbelievably slow. Same thing if I use one of my other Macs in place of the WinPC, so it looks like a network or iMacG5 issue, not a WinPC issue.
On the other hand, if I use Airport to connect a WinPC, eMac or MacBook to the iMacG5, the file transfers are blindingly fast.
Is this perhaps because the FW & ethernet controllers in the iMac G5 are the same PHY chip? Is this some kind of contention for bandwidth through the PHY chip? (The Airport card in the iMacG5 is on a separate bus, not connected to the Ethernet/FW PHY chip, which makes me suspect something is up with the ethernet/FW controller.)
Anyone else encounter a problem like this with slow file transfer through your iMacG5 to an external FW drive?

Martin, that's really interesting. I've noticed slow network transfers in the past but always racked it up to overhead and parity errors inherent in the OS's. Never thought it might be the PHY chip, though it certainly could be. Apple has a broadband tuner which might help you by increasing packet size (but you probably knew that as a Level3). My stopgap is to do the file transfers with firewire, but your laptop may not have that option.
You could maybe copy to the mac over the network, then copy a second time to the LaCie. Not elegant or clean, but will save you time. Kinda like taking the backroads to avoid rush hour traffic - it's farther to go but you get there faster.
I'll look into the controller question. Let us know how you're doing,
Ed

XP to XP slow data transfer - WRT54GP2

I have two XP sp3 machines in my network. Data transfer between them caps at 1Mbps. This is very odd since both machines have tested at speedtest.net at 15M down and 1M up. Why is my network transfer so slow? What can i try.
A little about my network. All cable is new cat 5e. There are 10/100 NIC's in each machine set to auto negotiate. I have tried setting the NIC's to 100 Full Duplex with no success. Both machines have static IP's assigned. All anti-virus and firewalls are off. Both machines are on the same workgroup and can see each other.
Cable modem connects to a Linksys WRT54GP2 router with built in 10/100 switch. I assume it "auto negotiates" since i cannot find a setting for it.
Machine "A" connects from router through a set of Netgear HDX101 Powerline HD Ethernet Adapters then to the machine. I have also tried bypassing the Powerlines and transferring the data over WIFI. I only get up to 1.5 MB/s transfer speed. My WIFI says im getting 54 MB/s. I was hopping to see near 25 MB/s at least.
Machine "B" connects directly to the router via cat 5e.
I also have a MacBook on network too. It's wifi also suffers from the same transfer rate. If the xp-xp fix doesn't also fix the MacBook i will open a new post about it.
I have read ssoooo much about similiar issues to what im having. im really hoping on of you can help. thanks.
Cesar

The Internet Speed Test and the Data Transfer Speed are the 2 different Things, You Internet Speed is nothing related to your Data Transfer Speed between your Computers. As GV suggested you, connect the Cross Over cable between your computers and assign a Static IP to your both the computers and then transfer the data between your computer and check at what speed the data transfer speed is going on.

Slow network printing on Windows 7, fast on Windows XP

My system is dual boot. I can either boot in XP SP3 (32 bit) or Win 7 (64 bit). When I print an 8MB file to my CM2320nf over the network through XP, it takes 5 seconds to transfer the data from my PC to the printer. When I print the exact same file using Win 7, it takes 45 seconds to transfer the data.
Since both times they are printed from the exact same PC, this rules out stuff like settings on the printer, or router/switch settings, etc. It must be something in Windows 7 causing the slow data transfer.
I've compared settings in XP and Win 7, and the only difference is the Print Processor used. In XP, HPZPP5k4 is used. On Win 7, it's hpcpp03. Could this be the cause for the slow printing in Windows 7? How can I add/install a print processor in Windows (and where can I find/download HPXPP5k4.dll anyway)?

Slow Data Transfer on Server 2012 R2 Essentials - Can't Disable SMB Signing

I've seen several solve their slow file transfer rates by disabling SMB signing (that is, workstations connected to the server can move files from folder to folder, but it takes forever, whereas if one is logged onto the server through a third-party client
(like TightVNC), one can easily move files from folder to folder--no delay).
I thought I'd do the same as one of my clients is suffering this problem.
Unfortunately, the necessary items ("Microsoft network server: Digitally sign communications (always)" and "Domain member: Digitally encrypt or sign secure channel data (always)") are greyed out and I can't disable them. I'm logged in
under the administrator account.
Is there another work around?

Hi MarKomus,

Unfortunately, the necessary items ("Microsoft network server: Digitally sign communications (always)" and "Domain member: Digitally encrypt or sign secure

Based on your description, I understand that you want to configure those two group policy settings in client
computer, and then find that they were greyed out and can't be disable.
Just addition, please logon your Windows Server 2012 R2 Essentials via Administrator account. Then open Group
Policy Management Editor and follow the path: Computer Configuration-> Policies-> Windows Settings-> Security Settings-> Local Policies-> Security Options, then please check if that two policy settings had been defined and configured in the

Slow network with Time Capsule

Hi There!
We have a network at home consisting of a Time Capsule (to provide wireless to the house as well as to hold all of our iTunes content and use as a file server), two Mac Pro towers, a MacBook Pro, an iMac, and two Windows-based notebooks, and an Apple TV. We are NOT using the Time Capsule for backup.
The problem we're having is that the network is incredibly slow. Trying to copy a large file over the network can take hours when it should only take minutes. And we can't stream shows/movies in iTunes from the Time Capsule because it pauses every one or two seconds to catch up. We also have business grade cable modem service but we can't do iChat videoconferencing without the audio/video completely dropping.
We tried purchasing an Airport Express to extend the range of the signal (and even purchased a second one!) but those didn't help, either. The firmware on all devices it up-to-date. And the network is closed (no one is leeching).
Are there any tools, either built in to OS X or another source, that can help us diagnose what's wrong with our network? What other things can we try to diagnose the slow network?
Thanks!

First of all, be aware that the more devices you connect to a wireless network, the slower it goes. In addition, if you have devices that only work at B or G speeds, all devices on the network slow down to the slowest device.
For example, when you have a 300mbps N device and a 11mbps B device connected to the same network, they'll both go at a maximum speed of 5.5mbps. You are limited to 11mbps because of the B device and then further limited to 5.5mbps because there are two devices sharing the total (11mbps) bandwidth.
As far as testing out your current connection, try these:
1. On a mac, you can hold down Option and click on the airport/wireless icon. This will show transmit rate and other information. The maximum transmit rate for N devices is 270, G: 54, B: 11. If the transmit rate is very low, this indicates a poor wireless signal
2. Change the wireless channel used by your time capsule to something else. Try them all to see what gives you the best wireless signal
3. In the airport utility, select the time capsule, go to manual setup, go to advanced, click on Logs and Statistics, then click Wireless Clients. This shows the transfer rate, noise, and signal for each device connected to the time capsule.
4. Download iStumbler. This mac application will show other wireless networks in the area and what channel they're using. It is typically not good to set your network to use the same channel as others in your area.
5. Download some sort of application that shows transfer speeds (like iStat Pro). Test transferring large files between computers to see how fast it goes with different setups.
There's a few things you can do to improve wireless performance when bogged down with too many devices:
1. Turn off any wireless devices not in use. If it's on, it's using bandwidth space even though it's not transferring data.
2. Use multiple routers or a dual-band router to create separate networks. For example, you can make the time capsule make a 802.11N-Only network which will only the new N devices will connect to. Plug an express into it and make it create another network (G-only or B/G-only). Keep plugging in additional routers and make new networks as needed.
3. Replace older B/G devices with N devices if possible.

(Slow Network): iSight camera not working in iChat since Leopard upgrade

I have a different type of iChat video issue. My Power Mac G4, 867 MHz, 1 GB DRAM is a supported Mac for the Leopard upgrade. I've successfully installed OS 10.5.
Also my Power Mac meets the iChat Conferencing Requirements for 1-on-1 Video Chat per the OS 10.5 system requirements and the application note here:
http://docs.info.apple.com/article.html?artnum=301050
My iSight camera is connected via Firewire to an Apple Cinema Display, which feeds back to the Power Mac G4.
1) When I boot from my 10.3.9 Carbon Copy Cloner backup my iSight works in iChat (at least locally to see myself) without any issue. Green light comes on and shows me locally on video and audio sound bars. Before the OS upgrade the iSight worked fine for live video conferences with iChat 2.1.3 under Mac OS 10.3.9
2) Running OS 10.5 when I go to iChat 4.0's preferences video pane the following message is waiting "This computer does not support video conferencing."
3) With Leopard iChat 4.0 the Connector Doctor under "capabilities" says "(Slow Network)" for 1-on-1 Video Chat and won't even show video locally or turn on the iSight's green light.

Fixed!
My Power Mac Quicksilver G4, 867 MHz. problem with (Slow Network) in the iChat Connection Doctor, no video preview or video iChat since upgrading to OS 10.5 Leopard and iChat 4.0 has been solved with the following posted towards the end of the thread below.

IChat over slow network

Hello,
I'm not really good with network stuff, so I know very little about my problem here. I'm working on an offshore drilling rig and they've recently set up a wi-fi system for personal use. It's very slow and governed by the nanny Websense.
I know some people are able to use their IM chats and I was wondering if there is a way to set up my iChat to work on such a slow network. It won't connect at all when I'm here. I know I won't be able to video or audio chat, but I should at least be able to text chat, shouldn't I? Or is it possible that Websense has blocked certain IM's and not others?
Any suggestions would be appreciated!
Lawrence

Hi,
In iChat go to the Preferences > Account section
GO to the Server Settings tab
Whilst logged off of AIM chnage the port to 443
Log in to AIM.
This is because the regular Login port is 5190.
The AIM Application on a PC or in fact the AIM for Mac application will automatically try other ports including the web browsing port (80) to make a connection.
The port 5190 is above a Threshold of 1024 where ports have to be opened specifically. Using port 443 is below this and also used fro Secure Mail by mail applications so is likely to be open.
