Very slow lan!

Hello to all. first of all sorry for my bad english.
my configuration is:
Mac Pro 1,1
2 x xeon 2 ghz
7 gb memory
8800GT
Mac osx 10.5.8
the problem is that: my network perfomance are too bad, the lan transfer (internet traffic from router to mac pro, from mac pro to printer epson trough lan) is very slow and no linear, go like a AC (see this image: http://img194.imageshack.us/img194/4758/networkt.jpg )
when there is this problem using more than one hour to print an A4 photo
to restore and dab the problem must continually undertake a maintenance application (like onyx) and run script commands and maintenance of cleanliness of the various cache. done so, turn off and reboot.
thanks for attention. have a nice day.

the router is a Netgear ProSafe DGFV338, the Mac PRO and the printer are connect with a cable (no wi-fi). i haven't this problem when using the notebook, therefore rule out a problem to the router.
yes, i have tried to power off all component.

SCCM 2012 - Very slow LAN software deployments

Earlier this week I created a package containing office 2013 SP1 ready to deploy to our workstations
I have been installing the office 2013 package onto desktop computers on our LAN and it is being very slow on downloading the application from the DP.
The DP is on the same as the workstation and it appears to utilize less than 1mb of the 100mb local NIC card. I have also checked and the boundary config is set as a fast link. Has anyone come across this before?
When looking at the NIC on the DP server it is using 2% of its 1GB connection. I have also checked the distribution log and it is downloading from the local DP.

Thanks for your quick response :) That seems to be exactly the setting.
One question if you know the answer, If you define a boundary as having a slow link what happens to the traffic? Does this no longer do this slowly using BITS.
I can see this would be why this setting was set as we also have slow link sites without a DP

Very slow LAN connection on my Tecra M1

Hi all,
I use a Toshiba Tecra M1 1.6 GHz, Win XP.
I found that there is something wrong with the LAN connection. It is very slow. I takes about 5 minutes to download 1 MB. It is really time consuming if I want to download and update some software through internet.
I also have one desktop. it is a bit quite old but LAN connection is much faster than my laptop; for instance, I downloaded Windows Mediaplayer 10 - about 12 MB by using desktop and latop at the same time to compare, the desktop took 2-3 minutes while the laptop ate more than 20 minutes. I have exchanged the cable between the desktop and laptop but it did not help.
Does any one know the potential problem and solution?
Many thank.

Hello
Nick is on the right way. Who knows what runs in the background and which applications wants to access internet. I recommend you to use tool called Zone alarm. On this way you will have the whole control about applications who want to access the internet.

Very slow LAN speed

I have a "MI424WR" router. Various pages say it has speeds up to 12 mebabyte/second transfer rate, but I am only getting no more then 3mb/s ever.
I have 1 desktop that is wired and 1 laptop that uses wireless
Help is apprecitated

Since you refer to slow LAN speeds, I assume you're referring to a transfer between the wired desktop PC and the wireless laptop.
Any transfer between the two is going to be constrained by the slowest component, which is your wireless connection.
You said you're getting "Mob/s". I'm not clear if you're referring to megabits or megabytes.
If that number is megabytes, that's about average for a wireless-G connections.
MOB/sec (note the caps) * 8 bits/byte = 24Mbps
If you meant 3Mbps, then you're probably dealing with a wireless interference issue and should look at the usual wireless troubleshooting issues, such as changing the channel, eliminating sources of interference, etc.

Very Slow lan speed at WRT54G v8

Hello folks,
I'm very sorry to bring this issue to you, but I've checked all the information avaliable at the forum and was not able to solve my problem. Here it is:
I have in my house total of 4 devices:
2- PC (P4 2.0 Gh 1 gb RAM) running Windows XP SP2 (hereby Pc 1 & Pc 2)
1- Notebooks (Core 2 Duo) running Windows vista (hereby Note 1 / 2 & 3)
1- Playstation 3 (hereby PS3)
Before I buying my Linksys router I used an Thomson Speedtouch Modem as router, and all conections were wired. I had no problem at all. Upnp at this modem worked very fine, and wired transfer files on my network worked very fine (transferences at 9 mega bytes per seccond)
Now, I've changed my router to wireless WRT54G v8.
PC 1 & PC 2 are using cables
Note 1 and PS3 are using wireless conection
The internet conection works very fine. I have an assymetric internet (very commom in brazil) and I get 400 kbytes per seccond downloads, which mets my desire (speed is ok)
But I'm having a hard time with the wired conections...
I'm using PC2 as a download center. So, I download everything using this PC 2 and then share through the other computers on my network.
But, if I try to download things FROM PC 2 to PC 1 I get about 30 kbytes per seccond speed (previously it was 9 megabytes per seccond)
If I try to download things FROM PC 1 to PC 2 I get 9 megabytes per seccond speed (which is fine)
If I try do download things from PC 2 to Notebook 1 I get 1 megabyte per seccond speed
If I try to download things from PC 1 to Notebook 1 I get 3 megabyte per seccond speed
Since I havent changed the cables from the previous instalation, the only responsible for the problem, as far as I can see, is the WRT54G router.
Things I've tryed so far
- Configuring firewall for correct IP authorization
- Changing MTU to 1400
- Changing the network card speed to 100 mbs full duplex on both computers
But the problem did not go away.
I would be very happy if any of you could provide me ideas to solve my problem.
Thanksa lot!

Sorry to bump this article, but my problem is not solved...
I've tryed several things, but the problem cannot be solved...
One thing I could figure out is that I cannot ping the PC which sends files very slowly.
This could indicate that the problem is firewall related, but, checking Norton configs, it seems that everything is OK. Even if I desable completely, the problem still occour... Windows firewall is also desabled...
I'm considering the idea of removing Norton firewall completely, because I think is related to it.
Any thoughts??
I've also tryed:
changing network cable
changing network card
and the problem still occour...
Help??

ARD 3.7.2 very slow connection on Lan

I'm running ARD 3.7.2 on MacBook Air (OSX 10.9.2) to connect mac mini (8gb / osx 10.9.2) very slow connection on LAN.
Mini connected to LAN 100Mbit Ethernet, MacBook connection is wi-fi

Ok, I solved it after doing some extensive Google searching. Still not sure why ARD went bonkers, but here's my fix.
1. Download the ARD 3.7.1 client drom the Apple downloads page and install it manually on the client machine.
2. Go back to the administrator machine and delete the computer client from the computers list.
3. From the scanners list, find the now visible client machine (it will probably say "no user name or password" next to it) and drag it to the computer list.
4. When you drag it over it will ask for the username and password. Fill in an administrator user name and password for that computer, click OK and you're done.
Still a mystery as to why ARD software itself will not create new client packages. I still haven't figured that part out. Downloading the standard client package from Apple is the only work around I know of so far. Good luck.

Exchange 2013 - outlook in LAN environment very slow upload but fast download - not using 'use cached exchange mode'

Hi,
I have Exchange 2013 setup in a new environment (no migration) and it is working great except I just realized there is a big problem.
I notice the following
Problem 1:
Outlook 2010 with sp2 with cached exchange mode on: when I import the pst into outlook, it imports fine but the sync is extremely slow. It uploads to the Exchange 2013 mail server at 20-70KB/sec (bytes) via LAN.
Problem 2:
Outlook 2010 with sp2 with cached exchange mode off: when I import the pst into outlook, it imports extremely slow. It uploads to the Exchange 2013 mail server at 20-70KB/sec (bytes) via LAN.
More info:
-user1 has 1GB of mail and when setting up the user on a new pc with outlook with cached exchange mode on, it downloads the mail very fast. It downloads at 40-80 Mbps/sec (bits).
-I have Exchange 2013 with CU3 with win2k12 non r2.
Why is the download so fast from Exchange 2013 but the upload to Exchange 2013 is extremely slow? How do I fix this?
Thanks

I did some more testing.
I setup a test environment with:
-Exchange 2013 SP1 on win2k12 r2
-Outlook 2010 SP2 on windows 7 sp1
-Outlook 2010 SP2 on windows 8.1
-Outlook 2013 SP1 on windows 8.1
Both windows 7 and windows 8.1 have the very slow upload issue to Exchange 2013. Windows 7 upload to Exchange 2013 is around 20-70KB/sec (bytes) via LAN. Windows 8.1 upload is a bit more responsive at around 500-600KB/sec (bytes) via LAN.
I changed the TcpAckFrequency to 1 for windows 7 and 8.1 and the problem went away. The upload on both Windows 7 and 8.1 was going at megabytes after the change.
I hope Microsoft fixes this soon.
PowerShell script to have this automated via GPO:
http://community.spiceworks.com/topic/571571-outlook-slow-after-migrating-to-exchange-2013
PowerShell Script:
$strGUIDS=[array](Get-WmiObject win32_networkadapter -filter "netconnectionstatus = 2" | select -expand GUID)
foreach ($strGUID in $strGUIDS) {New-ItemProperty -path HKLM:\System\CurrentControlSet\services\Tcpip\Parameters\Interfaces\$strGUID -propertytype DWORD -name TcpAckFrequency -value 1}

Very slow network connection via LAN or Wifi problem

Hello,
I am running Windows xp MCE version on my Macbook 2.2. I have a very bothersome problem with my network speed at work.
When I run Windows on my Mac and connect to the network of my workplace using LAN or Wireless, I can surf the local websites and Email by a very nice speed but when I try to open any page outside the companies website, it is very slow or sometime it does not even open it. In status bar it says "Waiting for www...".
I tried almost everything. The problem does not come from my firewall(I even unistalled it). My network setting are like everybody else. I dissabled the auto Comunication speed. nothing seems to help.
It seems to me that this is a problem with windows on Macbook.
I was wondering has anybody a similar problem?
Does anybody has any solution for that?
Thanks

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.

Exchange 2010 performance is very slow

Hi Team,
One of our Exchange 2010 server is running very slow,
My problem is when i remote desktop do my Exchange servers, everything is so slow.
Any idea's what could cause this?
Thanks,
Sivakumar Thayumanavan

Hi Jatin,
Please find the answer for your question.
1. Server is virtual or physical - Virtual
2. If virtual then RAM is static or dynamic - Static
3. Is the RDP only slow or when you log on locally also - RDP only slow as the server is virtual server
4. If only RDP and its a Virtual machine then by any chance you have a broadcom lan card..??
what task manager is showing.. can you share the screen shot.

My internet speed suddenly went VERY slow on all browser

I am running on a Mac OS X Lion 10.7.5, 2 Ghz Intel i7, 4GB Ram DDR3.
I am experiencing very slow internet speed after some system update some time ago.
I have tried using wireless and LAN cable but both results the same.
I've tried resetting routers in both my office and home but it is still as disappointing.
Kindly advice on what to do? I've forgotten which update is it as it is some time ago already.
I have installed bootcamp in my macbook and tried the using from windows but there isn't such issue. The internet was smooth and great.

Try these basic troubleshooting steps.
1. Quit all app scompletely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
2. Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
3. Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

AFP Directory Listings via VPN very slow in Finder

Hello all!
I recently exchanged my existing Apple iMac Core2Duo (with Mac OS X 10.6.8) to a brand new iMac 27" i7 (10.9.4). Besinde to this new iMac I´m using a MacBook Pro 15" (with 10.6.8). WLAN/Airport is turned off; only Ethernet / LAN is used.
My problem right now is: since the upgrade to OS X Mavericks we are experiencing server problems, browsing AFP shares on remote servers (VPN). The Directory Listing is very slow an can take up to 30 minutes for large listings. I can't browse network folders with Finder because it's too slow. It takes forever just list all the subfolders. If I try to transfer or open a file, everything is fine and I can do it at the right speed.
Here's the setup
2 networks are connected thanks to a VPN connection.
All clients, in all connected networks can communicate to a common fileserver (MacPro with OS X 10.6.8 SnowLeopard Server) in Network A
Firewall is not an issue between those networks
The clients authenticate via OpenDirectory and Kerberos to the fileserver
So the problems occur if i want to connect a client on network B to the server on network A. Connection, authentication, ... all good. Even the performance over the VPN, to tranfer files is OK. But browsing subfolders is catastrophic. I used AFP , results are the same. I also made tests on older clients, to see if the fileserver is the problem. 10.6 and 10.8 clients can browse normally, speed is OK.
So my question: What can I do to accelerate the browsing of my AFP/SMB shares for all my Mavericks clients? What can I do to speed up the Directory Listing? And yes: i know about solutions like PathFinder, TotalFinder, .... but i'm more interested in a native solution to this problem.
Thx!!
OS X Mavericks (10.9.4), 10.6.8 Server

This has been a major issue in Mavericks all along. SMB has been a total disaster for anyone who works with MACs on a corporate network, causing admins night terrors, anxiety disorders, and general sadness. 10.9.4 + some server side fixes (smbcreditsmax and smbcreditsmin) fixed many of the issues, but the slow finder listings over VPN connections is still unusable. the only workarounds i know of are:
- switch to windows
- downgrade to mountian lion
- use FTP or webDav protocols
- use a 3rd party finder replacement: mucommander (clunky additional app but works!)
I will be testing Yosemite beta this weekend, i have heard reports that some of this nonsense is fixed.

Photoshop CS6 - Very Slow Brush Speeds...

Hi:
I thought CS5 was bad, but brushing with CS6 all brush strokes are very, very slow. If I make a brush stoke I have literally have to put my hand on my chin and wait for the brush to catch up. I cannot work like this. Any suggestions on what to do to speed up the brushes? Forget about adding anything else to Photoshop, please work on speeding up exisiting functions.

[SOLVED] Network speed very slow, no apparent reason

Hello, recently I switched from Windows 7 RC1 to Arch on my home machine (I have used Gentoo, Ubuntu, and Fedora 10 on the same machine in the past), and for some reason network speed is very slow.
I have Verizon's 20mbit/5mbit package, and I have always gotten that speed.
Using speedtest.net and 100mb.test from cachefly on multiple computers I have come to the conclusion that it is infact my Arch install that is causing the problem:
- All other machines on my network are getting 20/5 (both wired and wireless)
- I ran a speedtest from 2 other machines using the ethernet cable that this PC is on. Again, full 20/5.
- scp transfer of 100mb.test from this PC -> other Arch box: ~2.8MB/s.
- scp transfer of 100mb.test from other Arch box -> this PC: ~2.8MB/s.
- scp transfer of 100mb.test from this PC -> UK VPS (100mbit line): ~539KB/s
- scp transfer of 100mb.test from UK VPS -> this PC: ~76KB/s
- scp transfer of 100mb.test from this PC -> Chicago Server (dual gbit lines): ~563KB/s
- scp transfer of 100mb.test from Chicago Server -> this PC: ~91KB/s
speedtest.net result:
Upload speed seems to be unaffected.
I have tried disabling TCP window scaling, and appending my hostname to /etc/hosts.
What is weird though is that the other Arch box has an identical network config, I don't see any reason why it shouldn't work.
My NIC is an integrated Realtek something, I can get the exact model if needed.

Hi, whipsch
Can you try ethtool to see if your ethernet card is actually negociating and using a 100Mb full duplex link on your LAN ? If not you can try to force the link parameter with ethtool. Also maybe the driver of your NIc has options related to link negociation.
Hope this helps,
JF

Time Capsule VERY slow ethernet back-up on my iMac

Hi anyone who can help....I'm getting really frustrated with Time machine
It seems quite afew people are experiencing problems with TC....
BUT they all seem to have different issues. Mine is simple.
As a wireless network it works just fine, last weekend i had some friends over and we had 4 laptops going at once - speed was fine
Backing up - My G4 powerbook works FLAWLESSLY, backing up wirelessly.
BUT...My G4 iMac (connected directly via ethernet cable) hasn't been able to do a back-up since got it. It gets stuck on preparing or takes day's (Yep DAY's) to do a few 100 MB.....
Obvoiusly the TC is working, but not the wired connection. I can't try my iMac wirelessly, as it doesn't have an airport card
ANY suggestions? Oh and I don't have any virus software installed

Andrew,
*_Slow Time Capsule Transfer Via Ethernet_*
*Disable Anti-Virus Software*
“Using virus scanning software can make Time Machine backups very slow. If you use Norton Antivirus 10 AutoProtect or a similar product, try turning it off during backups.” [http://docs.info.apple.com/article.html?path=Mac/10.5/en/15140.html]
*Create An “Ethernet Only” Location*
While you are physically connected to the Time Capsule via ethernet you may still be experiencing slow data transfer speeds because your Airport network is still active and taking priority.
Connect one end of a Cat-5 Ethernet cable into one of the LAN ports of the TC (<•••>) NOT to the WAN port (wheel icon). Connect the other end to your Macs ethernet port.
Next, go to System Prefs --> Network.
At the top of the window note what “Location” you are currently using, as you will need to return to this setting later.
Now, change “Location” to “Edit Locations”.
Click the “+” button and create a new location named “Ethernet Only”.
Click “Done”.
In the Services Pane on the left, eliminate all other services using the “-” button leaving “Ethernet” only. If you choose to leave other services listed then al the very least move Ethernet to the top of the list using the Action Menu (gear button) at the bottom and "Set Service Order".
Verify that “Configure” says “Using DHCP”.
Click "Apply" in the lower right.
You should be seeing an assigned IP Address and the Status should say “Connected”. The dot beside “Ethernet” should be green.
Now begin your backup or transfer of files.
You should still have internet access during this period.
Once the backup/transfer is complete, remember to change the Network Prefs “Location” back to “Automatic”, or whatever setting it had originally been, to restore Airport connectivity.
*Adjust Ethernet Speed*
Open Network Preferences.
With Built-in Ethernet selected on the left, click "Advanced" in the lower right.
Click "Ethernet" tab on the far right.
What is selected beside "Speed"?
Try changing this setting and see if it makes a difference.
Next launch Airport Utility.
Select the Time Capsule on the left.
Click “Manual Setup”.
Select “Internet” from the toolbar.
Click “Internet Connection” tab.
Near the bottom verify that “Ethernet WAN Port” is not set to a slower speed. Either choose “Automatic” or the fasted speed available.
If you have made any changes, click “Update”. 
*Slow Full Backup After Restore*
Try either deleting the “old” backup disk image or copying it to another disk. Then start the “new” full backup again. Some users have experienced improved speed when the “old” disk image was removed from the backup disk.
Let us know if this was helpful.
Cheers!

Very slow lan!
