How to Measure file transfer speed in iChat

hi guys, is there anyway to measure the file transfer rate ,while sending o receiving a specific file
in iChat?

Actually I should say that it's not a good solution to stop all other applications to measure the network
traffic for one application, there is another problem cause even no file is during transfer the application sends and receives packets from internet and this way is not accurate to measure .

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

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.

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.

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?

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.

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.

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.

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 to see the file transfer speed on a mac

Hi, I'm kind of a beginner with a Mac, I have worked on windows for all this years and now I have a small dilema. Can someone please tell me how you can see the file transferring speed on a mac. When you copy and paste from one drive to another, or from time capsule to my mac, etc a dialog appears showing you a progress bar and the time remaining. I would also like to see the speed of the transfer. Is it posible to see this variable?

In windows - vista when you copy or paste a folder from one location to another in the file transfer pop-up you can see the speed of the transfer.(You must press the more details arrow on that pop-up). Does Leopard has any configuration for this kind of information.
I will try iGet and write here my feedback.

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?

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?

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.

File Transfer? Faster - iChat?

My daughter is away a college. I would like to send her files that are rips of DVD (350 Mb) she owns when she requests them. Currently we sent via file transfer in iChat. As you can imagine it takes FOREVER!
Is there a faster way? Even if it doesn't include iChat.

I spent 8 hours trying, Yummy, DynDNS, Pure-FTPd, none would work... I tried transferbigfiles.com, it would send small test files but wouldn't do the 700+Mb ones...
I was about to give up and one last Goggle search gave me this little nugget: In Mac OS X, how do I access my computer's disks from another Macintosh? @ http://kb.iu.edu/data/angb.html
Within a couple of minutes I had it working. I didn't need any outside software!!!
Leave it to Apple to give me everything I needed and I didn't even realize it!
Don't make it harder that it has to be....

File transfer speed and distance from base station?

I tested the file transfer time (outside with no obstructions) by moving a large video file between my MacBook and a computer wired to an Airport base station. The times were the same as distance increased until the connection dropped. Why?

Do the calculations.
(Although wireless qualifies more for voodoo project than science).
500MB translates to 5.7MB/s which is near enough to 46Mbits/s
500MB in 94sec is 42.6Mbits/s
That is really slow for 5ghz at such close distance to the airport.
What OS are you running? Please open the wireless diagnostics.
About Wireless Diagnostics - Apple Support
Run the wireless utility.
And get the actual link speed and how well it is working.
Then use iperf to get actual network speeds. Rather than moving a file test the link rates.
iperf is included in Mac OS and is available via terminal.
This post gives some clues. http://acidx.net/wordpress/2013/05/testing-a-network-connection-with-iperf/
I think your seeing a hold up due to slow ethernet say.. 100mbit ethernet will ruin any numbers you are trying to get in tests. As well as older slow Mechanical hdd in laptops.
But the link speed in the Utility will tell you the story.. if you link at 450Mbps which should be possible up close.. and it drops to say 200Mbps at a range of 130M you are still far faster than the rate determining step.. very likely to be a slow disk plus slow ethernet.
Go to the performance tab.. and keep it running as you move the computer from next to the Airport to the 130M point. You should see a pretty large drop in connect speed.. but you also need to keep this running as you transfer files.. since it tends to vary greatly during a file transfer.
For science experiments.. this is already a pretty good one.. you are trying to determine the rate determining step in a network system and why wireless is not causing the problem you expected. The use of actual diagnostic tools is great.. almost like science.
The big spike in this graph is me changing from 2.4ghz to 5ghz.
