New router fixed my slow my data transfer speeds

I've been living with a relatively slow internet connection for over a year without knowing it. When I moved here I had FiOS 50/50 installed. I didn't realize a big boost in speed compared to what I had before. But up until a month ago, I had been a light user. Only occasionally connecting a tablet or phone through Wi-Fi. I got a new computer lately and started transferring files via FiOS from a very fast and reliable remote server. I knew right away something was wrong.
To make a long story short the problem turned out to be the wireless router. At the time of installation, the router was actually an old model. I had no way of knowing this because the Verizon "My Services" page said I had a more capable piece of equipment. Besides being dated hardware, it evidentially wasn't working as well as it should have. Here, we willl fast forward through the processes of rectifing the issue to receiving the new router.
I am happy to report that considering the variables, I am getting the speeds I was expecting. To confirm this the speed and diagnosic reports are awsome. Doubled the download speed of the old router connected by wire from <25 to >50. Better than 7X the speed connected by Wi-Fi from <7 to >50.
It took considerable effort to resolve but it was worth finding out if these incredible speeds are achievable. And, they are.
Thanks for reading.

So what router did you get? Was it the Fios Quantum Gateway?

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.

Internal Disk to Disk Data Transfer Speed Very Slow

I have a G5 Xserve running Tiger with all updates applied that has recently started experiencing very slow Drive to Drive Data transfer speeds.
When transferring data from one drive to another ( Internal to Internal, Internal to USB, Internal, Internal to FW, USB to USB or any other combination of the three ) we only are getting about 2GB / hr transfer speeds.
I initially thought the internal drive was going bad. I tested the drive and found some minor header issues etc... that were able to be repaired so I replace the internal boot drive
I tested and immediately got the same issue.
I also tried booting from a FW drive and I got the same issue.
If I connect to the server over the ethernet network, I get what I would expect to be typical data transfer rates of about 20GB+ / hr. Much higher than the internal rates and I am copying data from the same internal drives so I really don't think the drive is the issue.
I called AppleCare and discussed the issue with them. They said it sounded like a controller issue so I purchased a replacement MLB from them. After replacing the drive data transfer speeds jumped back to normal for about a day maybe two.
Now we are back to experiencing slow data transfer speeds internally ( 2GB / hr ) and normal transfer speeds ( 20GB+ / hr ) over the network.
Any ideas on what might be causing the problem would be appreciated

As suggested, do check for other I/O load on the spindles. And check for general system load.
I don't know of a good GUI in-built I/O monitor here (and particularly for Tiger Server), though there is iopending and DTrace and Apple-provided [performance scripts|http://support.apple.com/kb/HT1992] with Leopard and Leopard Server. top would show you busy processes.
Also look for memory errors and memory constraints and check for anything interesting in the contents of the system logs.
The next spot after the controllers (and it's usually my first "hardware" stop for these sorts of cases, and usually before swapping the motherboard) are the disks that are involved, and whatever widgets are in the PCI slots. Loose cables, bad cables, and spindle-swaps. Yes, disks can sometimes slow down like this, and that's not usually a Good Thing. I know you think this isn't the disks, but that's one of the remaining common hardware factors. And don't presume any SMART disk monitoring has predictive value; SMART can miss a number of these cases.
(Sometimes you have to use the classic "field service" technique of swapping parts and of shutting down software pieces until the problem goes away. Then work from there.)
And the other question is around how much time and effort should be spent on this Xserve G5 box; whether you're now in the market for a replacement G5 box or a newer Intel Xserve box as a more cost-effective solution.
(How current and how reliable is your disk archive?)

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)

NI8451 SPI data transfer speed and SCLK setup time adjustment

I'm using NI USB-8451 SPI bus to do communication. I can not reach the speed of communication 4MHz (NI USB-8451 module advertises speeds up to 12MHz). Actrually the data transfer speed is much slower than 4/8 Mb/s. The 16k*16bit data cost around 800ms while it should be 128ms if the data transfer achieves 4Mhz speed. In the manual there is a SPI timing clock figure like this:
In the 4Mhz communication case, the t2 should be 0.25us. I wonder whether the low data transfer speed is due to t1,t3 and t4 since they occupy too much "dead time". If my guess is right, is there any method to reduce the t1,t3 or t4, espetially t3? I know that in the advanced API there is a way to add delay while I did not figure out how to reduce delay(t3). If my guess is wrong, what is the exactly maximum data transfer speed NI8451 can support? (not the clock rate)
Thanks for help.

Hi everyone. Im using the SPI communication with 8451 and Im having the same situation., since the serial flash memory I need to program is big enough, t3 (SCLK Setup time) and other "dead time" which I think is the time when buffer on the 8451 needs to be re-filled those are killing my expectation on the final results. I can't see a way to decrease t3 (~10uSec) and in the same way Im seeing something like buffering up to 100~110 bytes then, a ~1.5mSec delay appears on the signal waveforms. Did somebody have good results trying to avoid this?
Thank you.
Javier

NSS2000 - Data transfer speeds over gigabit ethernet

I've just installed a NSS2000 on a gigabit network. I'm aware that some of the promised features (like support for jumbo frames) are not currently supported by the current firmware (version 1.13).
However, even without jumbo frames, I'm puzzled of why I am seeing data transfer speeds of only 50megabits per second, or about 5% utilization of the 1000Mb/s connection. I was expecting at least 20% utilization.
Is this another limitation of the current firmware version, or is there a setting somewhere on the NSS2000 which I need to to tweak to increase data transfer speeds?
More background - it is the only significant traffic on the network during test, the ethernet controller driver on my PC is the latest available, and the NSS reports that it is connected at 1000MB/sec. The unit has two 1.5Tb SATA drives in it, which are configuered as RAID1.
Also - does anyone know when the next firmware version is going to be available, and which of the current known issues it is likely to address?
thanks
Graham

I should mention that the volume I am writing to is encrypted - is the answer simply that this is the fastest that the onboard CPU can decrypt the content?
An experiment to an unencrypted volume increased the LAN utilization to around 10% - so an improvement, but still not as high as I had hoped.
thanks
Graham

Significant slowness in data transfer from source DB to target DB

Hi DB Wizards,
     My customer is noticing significant slowness in Data copy from the Source DB to the Target DB. The copy process itself is using PL/SQL code along with cursors. The process is to copy across about 7M records from the source DB to the target DB as part of a complicated Data Migration process (this will be a onetime Go-Live process). I have also attached the AWR reports generated during the Data Migration process. Are there any recommendations to help improve the performance of the Data transfer process.
Thanks in advance,
Nitin

SuperDrive slow Data Transfer Speeds

I have several home movies DVDs I would like to loadback onto my mid-2011 27" iMac but it is taking for ever to complete the transfer. One DVD disk takes 6 hours because the transfer speed is crawling. I read up onthis and info says my HL-DT-STDVDRW GA32N (FirmwareVersion KE06) is made by HLDS and they have implemented riplock which slows the data speed way down to preserve SuperDrive life expectancy anddecrease noise level. How can I disable this riplock to restore the data speed. I bought this fast/expensive machine and the SuperDrive of all things is slowing medown. Completely unacceptable.

I was having a problem ripping store bought CD's to ITunes and opened a case with Apple for suspected hardware issue. Turns out the problem was Norton AntiVirus by Symantec which was blocking my external drives. Even though the CD is internal it was killing it. Once I shut off Norton everthing started working.
The way I came to figure out it was a Software and not hardware issue was that the Superdrive worked perfectly under Windows 7 inside of VMWare Fusiion.
If you have any sort of AntiVirus, try shutting and down and using the Superdrive.
My machine is the same , late 2011 with Firmware KE06

Slow VPN PPTP Transfer Speeds vs. Windows XP

I recently switched my father to a new unibody MacBook after years of Windows XP heartache. He uses a VPN (PPTP) connection to access files on the Windows 2003 server at work.
*On the Mac (10.5.5), the file transfer speed over VPN is so slow that it is unusable.* Leopard can connect to the SMB server easily enough but clicking on a volume shows nothing until, after a 2-3 minute wait, the file list finally populates. The old Windows XP machine loads the volumes far quicker and is noticeably faster.
We are using the same credentials and settings as on the old machine, but nothing we do will speed up the connection so that it is actually usable.
Any thoughts or suggestions? At this stage I am extremely disappointed in the Mac's ability to integrate with enterprise. I was so sure the transition would be seamless but Leopard is making basic tasks much more difficult. It's egg on my face!
Help would be much appreciated!
Thanks, jd.
P.S. My apologies if this has already been discussed. Searching didn't give me many relevant results...

Hi Joe,
College networks can have a lot of unusual security monitoring systems in place, so it's conceivable that they limit non-PC speed, but as you said, you've checked that.
There is a known issue with some Gigabit Ethernet capable Macintosh systems and some switches. This problem can be fixed by software configuration, so it's possible Windows automatically does it, but MacOS doesn't. Have a look at the instructions specified in this Apple article and see if it helps: http://docs.info.apple.com/article.html?artnum=303660

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.

Ridiculously slow airport disc transfer speed

I just set up a new AirPort Extreme on my existing network, and the airport disk feature is unbearably slow. The finder locks up for nearly a minute just connecting to the disk, and then again when i open a folder. It took over a minute to copy a 60k file.
I'm using a MacBook Pro (2ghz Core Duo)
Wireless Card Type: AirPort Extreme (0x168C, 0x86)
Wireless Card Firmware Version: 1.1.8.5
Right now the APE is set up to extend an existing network but I initially set it up as a new network and had the same problem. Is this really the best transfer speed i can expect?

No.
Depending on which network settings you have, you should be able to move 150-400 Megabytes to an Airdisk in a minute.
You are probably seeing either a network problem, or disk errors causing the AEBS to retry.

Limit data transfer speed

Hi,
How could i limit the transfer speed of a standard URLConnection InputStream.
Explanation would be appreciated.
Thank you very much.

I'm not sure if i understood you correctly, whether the following is a bad idea or good, but this works for me, the os BW monitor shows around 25kbps:
        try{
            URL url = new URL("ftp://ftp.sierra.com/pub/sierra/tribesvengeance/demos/tribesv_mpdemo.exe");
            URLConnection conn = url.openConnection();
            InputStream in = conn.getInputStream();
            BufferedWriter out = new BufferedWriter(new FileWriter("tvd.exe"));
            int c;
            double now = 1.0;
            long startTime = System.currentTimeMillis();
            long written = 0;
            double maxBw = 25;
            int sleepTime = 0;
            while ((c = in.read()) != -1){
                out.write(c);
                written++;
                now = ((System.currentTimeMillis()-startTime)/1000);
                parent.putSharedValue((written/now)/1024);
                if(parent.getSharedValue() > maxBw){
                    Thread.sleep(sleepTime++);
            in.close();
            out.close();
        }catch(Exception e){
            e.printStackTrace();
        }I will perfect this to ensure it doesn't eventually slow down to 0kbps and then implement the concept into my app.
Thanks for your help.

Data Transfer Speed

I inserted a data CD and copied & pasted a file from the CD to my MacBook hard drive. I could see that the speed of file transfer was about 2mb per sec. I also tried to copy and paste a file from a data DVD, and the result was the same. Has anyone tried moving files from a disc to MacBook hard drive? My optical drive is HL-DT-ST DVDRW GS21N.

same problem here...
burning speed is fine..when reading from the same media, the transfer speed hardly hits 1mb / sek
this affects DVDs and CDs...

Data transfer speed question

I am consolidating all of my old back up drives onto a single 1tb TC. I am surprised at the transfer speed however. I have the TC connected via ethernet but it is taking hours to move even a couple of gigs. At this rate it's going to take all week. I feel like I must have done something incorrectly.
Is it the write speed that is so slow?

WGulliver,
Consider these points, see if they have any bearing on your situation.
*Anti-Virus Software*
Are you running anti-virus software. Disable it and see if network speeds improve. The discussion boards are filled with users who are experiencing degraded network speeds due to their anti-virus software.
One poster observed: “I had the exact same problem 5 mins ago, it had taken 2 hours to back up 2GB, I realized I installed Sophos anti virus a couple of days ago. When I turned that off my back up is speeding through.”
Another contributor stated, “I am doing the first backup to my time capsule, about 71 Gb, It seems to be going about 1 Gb per hour. is this seem OK? I tried the ethernet connection and the speed was about the same. It has been going all night and after 12 hours it is at only 12 Gb of 71….I found the problem, I uninstalled Norton and the problem went away. It backed up in about 3 or 4 hours”
*Wireless Security Issue*
Some who have experienced degraded network speeds have isolated the problem to their wireless security setup. Try this:
Launch Airport Utility
Select your Time Capsule on the left.
Click “Manual Setup”.
Select “Airport” in the toolbar.
Click the “Wireless” tab.
Change “Wireless Security” to “None”.
Click “Update” in the lower right hand corner.
Wait for the Time Capsule to restart and then see if your network speeds improve.
Granted, this is far from desirable. But it does help to isolate the problem in you instance.
Let us know if either of these procedures helped.

Slow Data Transfer Speeds Between Macs.

Hello Can anyone please help?
When I transfer data between my MacBook and iMac it is taking ages and never used to be this slow a couple of months ago.
A 1 GB file is taking 2 hours. I am using an Airport Extreme 802.11n router on 5GHZ Wide Channel and when I check my connection using Network Utility it says 270 MBit/s.
Any help would be appreciated
Thanks
Shaun

I am having a very similar issue. I am copying iTunes music to a USB flash drive formatted to FAT32. It is very slow - not as slow as you have indicated, but still very slow. Someone mentioned it could be Spotlight indexing the USB drive. I am going to turn indexing off and try again - although it is taking a long time just to stop the current copy that I had in progress.
