4500EA LAN File Transfer Speed

My XBOX started complaining when I began using Windows Media Center to stream videos from my PC to my XBOX. I found out that I had a wireless G router provided by verizon which wasn't fast enough to stream videos. SO, I went out and purchased a 4500EA router expecting it to be the fastest thing I had ever seen.
Now it seems a bit slow when trying to stream video from my laptop to the XBOX and i'm a tad bit confused as to why. So I did a file transfer from a desktop wired directly to the router from a laptop in the same room wirelessly connected to the network and my speed is about 4mbps. 4MBPS!? This device is supposed to be capable of moving packets LAN side at 450MBPS.
Both of my PC's are quad core, newer model PCs. I've tried moving files now for several hours with the same results. I've toyed around with my wireless adapters, changed power settings, full duplex, half, changed mtu sizes, changed security settings. I'm out of ideas.
Is getting about 1% of the advertised bandwidth normal? Or is something wrong?

1. Without knowing the wireless adapters you use it's impossible to say how much you might get under very good circumstances.
2. The advertised 450 Mbit/s is as usual with networking the theoretical boundary which would be possible only under absolutely ideal circumstances not using 802.11. In reality a compatible adapter might get maybe 1/2 of that under very good circumstances.
3. In reality you often won't get a 450 Mbit/s or 300 Mbit/s connection rate (which is only an indicator for the signalling and encoding used) but only a 144 Mbit/s connection at least for the 2.4 GHz band because there is too much interference.
4. Toying around with settings usually makes things only worse, in particular if you don't carefully revert all settings back to the original settings.
5. What connection rate did you get with your desktop? What adapter is in the desktop?

LAN file transfer speed much slower than Internet file transfer speed

We have several Macs & windows machines on a Ethernet LAN with an X server. We also have an airport express and a repeater. The LAN will download an 85MB file in about 4 seconds but over the wireless network it takes 31 Minutes for the same file. What's the problem?
A wireless internet speed test yealds 1504 down and 1213 up and is about the same with the LAN connection.
Both the windows laptops and the imacs seem to have this problem. Any ideas?

Do you have any older wireless equipment that may be connecting at 802.11B, which would slow down your wireless network? For best results if you don't have have any 802.11B clients, switch your broadcast mode to 802.11 G only.
Just a thought.

Slow file transfer speed on OS X / Windows LAN

I have a Mac Mini with OS X Server (Yosemite) on a network of 5 Windows 7 PCs, the server hosts FileMaker Server 13 and also some files in a shared folder.
I notice the file transfer speed when copying a file from one PC up to the server's shared folder is around 350KB/second, is this an acceptable speed? how could I improve it?
Thanks for your help.

I'm having the same issues.. I recorded a bunch of video with the 4s.. now i'm copying them to my windows 7 pc with it peaking out at 900KB/sec. My corsair thumb drive in the same port gets 5-10x this speed. any luck getting faster speeds?

K8T Mstr2-FAR7 ---- File Transfer Speed

I measured file transfer speed between partitions, 1) both in the same physical drive and 2) each in a different physical drive. The measurements were made on WXP and WVT by using a file having 1048MB in size. Results are as follows:
1) Partitions in the same physical Drive
WXPx86 : 18.55 seconds
WVTx86 : 38.91 seconds
2) Each partition in different physical drive
WXPx86 : 9.31 seconds
WVTx86 : 19.13 seconds
Are the above results normal? Vista's speed appear way lower than the maximum allowed by SATA-150. The speed may be affected by many factors. My hardware spec is shown below. RAM is in single channel mode and is running as DDR333.
Could anyone shed light on the matter of file transfer speed?

It's because Vista is buggy, everybody knows this.
If you want speed, use XP.
And that isn't the only problem with Vista, also graphics is 3x faster under XP.

Local file transfer speed slow on E1200

On a local file transfer (computer to NAS or NAS to computer) my file transfer speed with the E1200 is way too slow. I would expect the Wireless N speed to be at least 54mbps (megabits per second), which would be equivalent to 9 MegaBytes per second.
In practice the speed of transfer appears to be at 8mbps (1 MegaByte per second). Here is a screen shot:
The speed is the same whether I copy from the computer (on a wireless N link) to the NAS, or from the NAS (on a 100Mbit ethernet port on the E1200) to the computer. The NAS is brand new, auto configured to a RAID-1 setup with two new drives.
Anyone know why this is? is the encryption (WPA2-PSK/AES) slowing down the transfer? The same problem occurred with copying a folder of photos as with copying this large file. I don't think I can upgrade the firmware on my device, as I have the first version of the E1200.
Solved!
Go to Solution.

Sabretooth --
There is no option to set the Qos to zero. I can set it to "auto" in which case the number has no effect.
I could set it to manual but it restricts me to a range as you can see from the graphic.
In case you are wondering, my internet speed is 10Mbps downstream, 5Mbps upstream. So I am getting the same speed for the internet that I am getting for a local transfer.
The next troubleshooting step is to bypass the wireless and hook my PC to the router. I will let you know if that makes a difference.

File transfer speed when on battery power

Hey there - I've noticed that my file transfer speed is ridiculously slow when i'm not plugged in to a power source. Even when my battery is fully charged it's super slow. This happens not only when I'm uploading files from a memory card to my computer but when I'm attaching files to an email, or even sending an email. I've asked other mac users and they say this is not the norm for their machines....any ideas?
thanks!
Sunny

additionally, you can disable power menagement for your wireless card completely through iwconfig's power option. I suggest you read the manpage for iwconfig, I have quotes the 2 related options for you.
txpower
For cards supporting multiple transmit powers, sets the transmit power in dBm. If W is the power in Watt, the power in dBm is P = 30 + 10.log(W). If the value is postfixed by mW, it will be automatically converted to dBm.
In addition, on and off enable and disable the radio, and auto and fixed enable and disable power control (if those features are available).
Examples :
iwconfig eth0 txpower 15
iwconfig eth0 txpower 30mW
iwconfig eth0 txpower auto
iwconfig eth0 txpower off
power
Used to manipulate power management scheme parameters and mode.
To set the period between wake ups, enter period 'value'. To set the timeout before going back to sleep, enter timeout 'value'. You can also add the min and max modifiers. By default, those values are in seconds, append the suffix m or u to specify values in milliseconds or microseconds. Sometimes, those values are without units (number of beacon periods, dwell or similar).
off and on disable and reenable power management. Finally, you may set the power management mode to all (receive all packets), unicast (receive unicast packets only, discard multicast and broadcast) and multicast (receive multicast and broadcast only, discard unicast packets).
Examples :
iwconfig eth0 power period 2
iwconfig eth0 power 500m unicast
iwconfig eth0 power timeout 300u all
iwconfig eth0 power off
iwconfig eth0 power min period 2 power max period 4
website with the current manpage:
http://linux.die.net/man/8/iwconfig
or simply:
$ man iwconfig

File transfer speed in Shared USB Hard Drive via Airport Extreme

I' am planing to buy one of this, but first I need to know what kind of file transfer speed I can expect when sharing USB drive via Airport Extreme 1000Mbps Ethernet.
Thanks.
Message was edited by: Robert81

most likely 14m/sec but normally 10.5 this is ethernet wired and usb attached. wireless would be about 8M/sec
Wired is good enough I use it for Finder copy frequently.

How do I see file transfer speeds?

Hey guys, does anyone know if it's possible for me to see file transfer speeds instead of just the time remaining in Finder?

Hi,
In song view, go to menu > view > view options and select bit rate, file type and size.
In preferences, you can change import settings to Apple lossless. When you use file > create new version you can now can now convert from aiff to lossless.
Create playlist based of file type being lossless.

IPhone File Transfer Speeds

I have two MacBooks and two iPhones and I'm seeing very different file transfer speeds between the two. Both have the backup option manually disabled to improve sync times.
Setup 1: iPhone 3GS with MacBook Pro (15-inch, Late 2008) model
Setup 2: iPhone 3G with Black Macbook (13-inch Mid 2007) model
The time it takes to sync video between the two is drastic with the newer model copying files in a few seconds, and the older setup copying files over 5-10 minute periods.
I have yet to swap the two iPhones on the two computers but from a technical perspective, I don't understand why one would transfer files faster than the other. Both are using USB 2.0 and I've already tried using the same cable for both. Anyone see similar behavior? Is this a facet of the older computer or older iPhone?

As an example, a USB host on a PCI bus will send or receive the data via the PCI bus; the stack will prepare the next data in memory and receive interrupt from the host. That's what I mean, how that's implemented.

New to MacBook - slow LAN file transfer problem

My new MacBook is painfully slow when wifi-ing to my house LAN.
I turned in my old G4 iBook for a MacBook (2GHz C2D, 2GB, 10.4.9, all updates). I have a LAN that consists of a wired 1G Ethernet backbone (a Mini and a Powermac G5 are wired in) and a Snow AEB that provides 802.11g wifi access to the LAN. The wired LAN connects to a D-Link GB Ethernet switch so the wired systems can exchange files fast. The switch connects to a D-Link EBR2310 router that connects to a cable modem to ComCast. The router has the latest firmware (1.05, it's an 'A' version router).
The Mini, G5, and MB are static IPs on the LAN. The D-Link router passes out DHCP addresses >100, with addresses <101 reserved for static LAN IPs. I use static IPs for network reliability when recovering from power outages and other unforeseen glitches. The LAN has worked very well in this configuration, with fast file transfers among machines and good stability.
With my old 802.11g G4 iBook, I was able to watch DVDs that are stored on an external FW drive connected to the Mini. No stalls, no pauses, no dropouts - MenuMeters showed an average throughput of about 700KBytes/sec on the iBook when viewing a DVD. I used both VLC and DVD Player with good results.
With my new MacBook, I can't view my DVD files. 802.11g network transfer rates to the MB (indicated by MenuMeters and by Activity Monitor) vary rapidly from a high of about 1.1 MBytes/sec to 20 KBytes/sec. Movies stall, skip, etc.
Simple file copies from one system to another are also much slower with the MacBook - an average of ~100KBytes/sec vs. ~ 1.5 MBytes/sec with my old iBook. In short, the MacBook is dog-slow in file transfers from the other machines compared with my old iBook when using the wifi connection, with no change to the network infrastructure in going from the old laptop to the new. I would like to fix this.
My AEB is set up in bridge mode (simple access point) with WPA2 security. All three Macs are completely current with latest updates, as is the Snow AEB. The MB has 4 bars of signal strength. Slow file transfer problem does not change when moving the MB to or from the AEB.
Curiously, when I download a large file (like the Intel 10.4.9 combo update), the MB shows a steady ~800KBytes/sec download speed, with none of the speed variation it shows with file transfers from either the Mini or the G5. File transfers to/from the MB to either of the other Macs are very slow.
Both the Mini and the G5 have Airport cards: when I switch them from wired Ethernet LAN to wifi LAN, they transfer files between each other at ~ 2MBytes/sec - about what you'd expect from an 802.11g protocol. So the slow file transfer doesn't seem to be due to the AEB, it seems to be specific to the MacBook. When I connect the MB using its hardware Ethernet port, files transfer just as fast as the other systems.
I have tried these measures, without effect on the problem:
- power off/restart of every component in the system;
- changing the AEB to an open network mode;
- changing the MB from static IP to DHCP;
- toggling IPv6 on/off;
- running no applications other than Finder on all systems;
Activity Monitor on the MB doesn't show anything sucking up CPU cycles during file transfers. I have plenty of RAM. The only thing I've changed in the network is the swap of the iBook for the MacBook.
Can anyone suggest what else I can try to make acquisition of this nice shiny MacBook a step forward, rather than a step back? Thank you!

Hi,
Did you want to use the Live Migrations for that?
We recommend that you configure separate dedicated networks with gigabit or faster speed for live migration traffic and cluster communication, and these networks should be separate from the network used by the management operating system, and from the network
used by the virtual machines.

File transfer speed in 10.5.2

Since installing 10.5.2 the transfer speed between two Macs sharing a wireless access point is abysmal. 1GB now takes 8 hours to transfer if copied through the Finder. It used to take about half an hour. Using rsync from the command line the same transfer still takes about half an hour, with no Speedup. This looks like a protocol issue rather than anything to do with the wireless setup.
Anyone getting the same problem?

Yeah. The same wireless network setups work fine with machines not yet brought up to 10.5.2. The problem has been seen both with 3rd party wireless routers and with Apple Airport Extreme. There's some indication the problem can even be triggered in wired ethernet transfers outbound from a 10.5.2 MAC if the file sizes are big enough and time duration of the transfer is long enough.
The two threads (cited above) pretty much cover what seems to be known about the problem from posters here. There's speculation that this is an instance of "silly windows" syndrome (see the threads). At least one bug report has been filed already (no word of any response yet). Here are the two threads again for convenience:

File Transfer Speeds

I know this topic has already been covered in some of the posts but it was replied that the latest version i.e., 6.20 would solve the bug. Which obviously it failed to do hence this post.
The latest version of skype 6.20 still gives a maximum speed of upto 4Mbps even if the clients are on Gigabit LAN connection. Version 6.18 used to stuck at 1.5 Mbps. Earlier versions (6.9) used to provide full LAN speed via skype.
Secondly, earlier versions of Skype didn't pass on the sounds of programs running on one of the clients but as I tested today, version 6.20 passes client sounds (and I'm not talking about speech) like music etc etc.
Is this really how upgrades are supposed to behave? Or is it poor quality assurance testing before making release public?
Disappointments since MS acquired this brilliant service.

Been having issues with file transfers for a while, didn't find out til I went to post here that Skype is now up to 6.21 (I was on 6.20.x but 'checking for updates' didn't find anything) so I uninstalled, installed fresh, and tried again. Still no good.
Not sure what the aforementioned previous discussions covered, but when sending a file my local connection gets saturated on the upload side. So my connection properties dialog shows my connection uploading faster than my internet can (somewhere around 800KBps, while my net upload is ~100), with everything else net related predictably slowing down. And the file transfer itself slows to a crawl.
Uninstalled the latest/current version of Skype, back to 6.16.0.105 as I read in some other advice, and am currently sending a file at my normal speed without any issue at all.
So if this was supposed to be fixed it most certainly isn't.
Note this isn't an anti-MS rant - I didn't install Skype until MSN/Windows messenger no longer worked. For my needs (IM, file transfer) messenger worked perfectly. Skype has been ok until recently with this issue.

Maximum Bonjour file transfer speed?

I have a question for anyone who transfers files over Bonjour with iChat. What's the fastest speed you've been able to achieve?
I got 20MBps today, consistently for a 5GB file. Here's my setup:
I have a great Asus 100Mbps router running Tomato. It's connected to a Linksys Gigabit router, which is running DD-WRT in AP mode. I have 2 macbooks connected to the Linksys using GigE. Since my file transfer was faster than 12Mbps, I know iChat isn't routing all that data through the Asus, which is impressive; I'm surprised it can do that so efficiently. But then I wonder, why can't it be even faster?

Measure file-transfer speed?

Hello to all of you!
I would like to know if there's a way to monitor the speed during a file transfer (either from the internal disk to an external, or from an internal folder to another internal folder). I'm not referring to online file tranfers (eg. FTP).
To help describe my question even more, lets say I'm transfering 5GB of data. I can see the estimated time in the progress window, but I'd like to view the speed at which the data is transfered.
Any tips?
Thanks a lot!

Efthymis , It really depends on just what you want to measure.....'Benchmarking'- which is what you are trying to do is (truly) a complex art - IF you want meaningful results...there are various special-purpose tools (you CAN'T rely on the computer's/program's estimates because they tend to be sec-by-sec and don't allow for start-up,overheads, etc etc and are usually quite misleading)...)
You WILL get different results if you transfer 100 * 1MB files compared to those you get if you xfer one 100MB file, for example.
Most accurate test of speed is a set of known filesizes:e.g 100meg, 500meg etc, a stopwatch and a quick hand.
For an accurate 'real life' test,include a folder containing 3 or4 real-life filesizes -e.g. a few 2kb, a few 100kb, a few 500k, a 1000k, a cpl of 5 meg, DUPE That folder a few times, place results in yet another then copy THAT somewhere whilst armed with a stopwatch
Otherwise, as I said here, there are various tools (see versiontracker and try a few of those)
best of luck

Please rank in terms of file transfer speed between FW800 external HDs

Hello,
I have two triple interface (FW400/FW800/USB2) 1000GB external hard drives. My 17inch Macbook Pro has 1xFW800 and 1xFW400. Please rank the following in terms of speed of transferring files directly between the external hard discs:
1. Connect one to FW400 and one to FW800.
2. Daisy chain FW800.
3. Buy a 2 slot FW800 express card and connect both via this card.
4. Buy a 2 slot FW800 express card and connect one drive to this card and the other to the inbuilt FW800 port on the Macbook Pro.
Thank you very much for your replies,
Ben

For things like file transfer with large files, the internal drive will be noticeably faster, because it is a single continuous action.
For booting and running a computer, there are many things happening at once, and disk access speed is only a small part of the overall process. Other factors related to the current status of the drives, such as amount of free space and fragmentation of system-related files will have an effect as well. If you perform a brand new system installation on a newly erased external drive, the system's files will be optimally placed with plenty of free space. Compare that to your internal drive, with the existing system's files somewhat more scattered over the drive (happens over time) and less contiguous free space (happens with ongoing adding and deleting of files)... The external drive may actually run faster.
I have Mac OS X systems on external FireWire (400) and USB 2.0 drives. The internal drive feels a bit faster, but it is not something that is too noticeable. The ideal setup to optimize disk access speed is a limited size internal drive volume (it can be a partition) with the OS and apps installed. This volume should be devoted mostly to the OS and apps and have a decent amount of free space. If the drive is partitioned, use the first partition. Your personal data is then stored mostly on your the other partition (if the internal drive is partitioned) or an external drive. This keeps the OS and application files confined in one fast portion of the drive, and reduces ongoing fragmentation of files and free space, because OS and app files do not change very often, compared to user data files.
However, for most users, the benefit gained is not enough to justify the added effort and complexity. One drive with everything bunched together is simple and easy, and works fine.
