How to test network speed

How do I test the speed of my network to determine if Time Capsule or my Internet provider is behind a real slowdown in my internet access. I ran the java test at DSLReports.com and got the following results:
Compared to the average of 971 tests from comcast.net: download is 98% worse, upload is 98% worse.
I'm unsure where to look or what to look for in trying to find a cause for the problem but wanted to at least try and make a stab at finding out before I called Comcast.

You could try connecting a computer directly to your broadband modem and run the test again. That would remove the Time Capsule from the configuration. You may need to reset the modem to convince it to connect to a "new" device.
Are you connecting to the Time Capsule via Ethernet or Wi-Fi? If by Wi-Fi, the quality of your Wi-Fi connection could have a big affect on the network speed. In that case, use the advice in the second message of this thread to investigate the signal and noise levels that your Mac sees:

How to track network speeds - maybe through SQL or open to others

The network speed is dramatically slower to the SAN, but it also makes me wonder how slow things are between the Webserver and the external world.
What's the best way to monitor what-I-assume are network delays and which part of the networks are causing the problem.

Hi,
You can use the tools like Resource Monitor and Network Monitor.
Resource Monitor is a tool that you can use to monitor the usage of CPU, hard disk, network, and memory in real time. You can open it by clicking the
Start button. In the search box, type Resource Monitor, and then, in the list of results, click
Resource Monitor. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.‌
Meanwhile, I think it is proper to dig the networking issue on the Windows Server forum via the below link.

How to discover network speed?

I'm a happy user of a mixed Mac (MacBook Pro) and PC (XP Pro SP3) home wireless network - unusual I know! My question is whether there is a way to get my MacBook to tell me what speed it is connecting to my Time Capsule-based wireless network?
The reason I ask is that my Windows laptop (Sony VAIO with a elderly "b" standard wifi card) tells me that it is only connecting at 1Mbps (occaisionally 2Mbps) - it used to tell me that it connected to my previous D-link router at 11Mbps. I appreciate that it might be lying to me in one or both cases but I would like to know whether I am getting as much out of the TC as I could. I determine the alleged speed of the network by hovering the mouse over the wifi indicater in the systems tray. It maintains this story regardless of whether any other computers are logged on to the network. I don't know how to do the equivalent in Leopard (I am a recent convert to Macs!)
I tried speedtest.net but it only told me that I have a miserly 3.9Mbps broadband connection (ie about the UK average) but at least it says the same regardless of whether I do the test on the Mac or the Sony. Shame I am paying for 8Mbps...
Thanks

Network Speed Required with VPN

Hi,
I have a customer, he has open an office outside the main company,
Only 2-3 user (with all authorization access to B.one) will be connected with VPN.
I would like to Know how is the network speed required to use b.one with VPN connections.
Thanks for your cooperation,

Hello
There's no specific definition for VPN.
What we recommend based on the field experience is:
_Terminal server_
Bandwidth per user: 20 - 40 Kb
_Citrix_
Bandwidth per user: 5 - 20 Kb
Please take these numbers as a recommendation/guideline and not as minimum requirements.

Standard local network speed test?

I recently setup up a dual-band (dedicated n, dedicated g) wireless network, and I think I am having some issues with throughput (qualitative observation). So I started trying to find a good metric for performance of the wireless systems. Note, I am talking here about the local wireless (Airport devices between home computers), not the connected internet speed (cable, DSL, fiber).
I see a lot of people copying files and timing the transfer. Is this the best there is? From what I've read, ping isn't such a good metric for network throughput. You can watch the kb/s transfer report on copy, but that isn't exactly stable or indicative of general performance. Any other tools, programs, methods, etc.? Or should I just be timing file transfers?
Thanks!

Yes, I know how to handle and suppress errors in LabView. I was mainly looking for a good example on a network speed test.
The test we have uses was written by one of our software guys, it uses two computers in a client-server arrangement and stops and displays an error message when the client computer loses connection to the server. Regardless of the reasoning I have given the programmer refuses to change it because he wrote the test for him and that's how he wants it.
I want a program that can use one computer with two network cards.
It will send a data stream out one NIC, through the UUT, and back in the other NIC.
Where it Will be checked for errors and dropped packets, and sent back through the UUT.
A continuous throughput speed measurment will also be logged along with errors, dropped packets, and retries.
I have never used any of the LV networking, tcp, etc VI's and was hoping someone had done this before because I do not have time to start from scratch.

Network speed test throughput monitor

I am looking for a quick and dirty speed test to continously monitor the bidirectional throughput of a transponder and POE device while they are undergoing environmental testing.
Would be nice if it could log throughput, dropped packets, and bit error rates between two computers and did not crash when a fault causes one end to stop responding like the C program we have now.
Our C programmer looks at us like we are insane when we ask him to not stop display an errror if the client or server times out.

Try this first - 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. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

Network speed test in jsp

I would like to know which APIs are necessary to develop a network speed tester in jsp or which method to do this, knowing about which APIs it's necessary, I will study them. Here is a example of a network speed tester that I'm trying to do
Examples:
http://www.coiinc.com/speedtest/initialmeter.php
http://www.pcativo.com.br/testes.asp?teste_tipo=velocidade
http://www.navegante.com.br/medidor/initialmeter.php
http://medidor.interair.com.br/
http://www.rjnet.com.br/velocimetro/index2.htm

Sir,
For at least a couple of these options it appears that the test is actually based on JavaScript.
What seems to happen is that at the beginning of the page there is a JavaScript variable that is set with the time.
Then there is a big amount of some sort of data. Which I would guess has been measured to be X big. Let's say 1 MB.
Finally there is another bit of Javascript which again takes the time and then finds out the difference and from that one can sort of conclude the time difference.
But I am not convinced this will always work perfectly but who knows... anyway your use of JSP wouldn't preclude you from just basically copying what these others are doing.
Sincerely,
Slappy

Any way to test the speed of my network?

My network is slow as molasses. Email takes a few minutes to send, netflix and Apple TV movie downloads take hours, etc....
I'm trying to figure out if the slowdown is because of my ISP or my local Airport Express/Airport Extreme setup. I would love to find a utility that lets me measure the speed of my network without the variable of including my internet connection.
For what it is worth, SPEEDTEST and PINGTEST are both giving me an F, even if connecting to servers that are only 50 miles away.

I would love to find a utility that lets me measure the speed of my network without the variable of including my internet connection.
If you are using wireless and you have Mac laptop handy, take some quick measurements at different locations around your home.
Hold down the option key on your Mac while you click on the fan shaped AirPort icon at the top of the screen. Look for the Transmit Rate number and jot that down.
This represents the maximum speed that your wireless could support at that particular location.
For example, let's say that your Transmit Rate at a given location is 130. This number is expressed in Mbps, so you would have 130 Mbps.
You will find that your network speed is much faster than your internet connection speed, which is limited by the type of service that you have selected. If you have a 6 Mbps service, your internet speed and connection will be limited to that number no matter how fast your network number may be.
Another way of saying the same thing is that your internet connection will always be the bottleneck on your network.

I am desperate!! slow choppy network speeds (not actual inability to cnnct)

I have a 13" macbook air that has the following problem: I can connect to wifi networks (including at home WPA and also tried WPA2 settings) but even though I may get proper speed at first, I soon lose that and it becomes much slower and choppy (if I open activity monitor I can see the speed going up and down like crazy...). My internet speed at home is 12mpbs set by my provider. When I perform speed tests (vis speedtest.net or downloading files from other speed test sites) on my windows PC that is also on this network I get the full download speed. However with this MAC while I initially did get the full speed, it is now down to an average of 3-5mbps and the activity monitor, again, shows choppy behavior so it will be at 8 then at zero almost and then up and down again but never near the full speed. I tried to connect to other networks and I have the same problem - once this happens it stays. I tried removing the airport connection in network preferences and adding it again it does not help.
I TALKED TO APPLE AND HAD MY COMPUTER TESTED BY THEM - they didn't find any hardware issues (they said it was fine - but it isn't) but they still replaced the airport hardware in the computer - both the chip and the antenna (which meant replacing the entire screen). I brought the computer home, ran a speed test and everything was fine. I thought GREAT but then something happened and the problem returned. What I did (which I think was unrelated) was connect via SMB to a PC at home and I tried to stream a movie file. I noticed it kept 'pausing' so I opened up activity monitor again and to my HORROR I saw the choppy wave with network speed very inconsistent going up and down like crazy... I tried connecting to my slingox using the sling web access after disconnecting from my home PC but got partial speed and lots of drops too. I tried the speed test again multiple times, nothing seems to work.
SO I don't know what to do at this point. I have 10.6.6 running. I heard something about a firmware update but I am new to mac so not sure how to even do that or what else I can do to solve this problem or what is causing it. BTW - logging in now from the guest account still does not fix the issues and they remain the same.
I am desperately looking for help!!
Thanks a lot!

Have you been able to reproduce your problems on other wireless networks other than at your house? It appears you are saying that this occurs on all wireless, but I'm not sure from your comment. If it's only at home, it would appear to be a compatibility issue between your wireless access point and the Macbook Air, which isn't uncommon. Sometimes a firmware upgrade to the access point can fix it, sometimes it might require switching to a different brand of access point. It would be great if you could borrow (or buy and return) a different access point/router to test. An Apple airport would be the best to use of course. Not the easiest solution, but lets you help rule out a hardware issue with your air.
My isp provides 15mbps but my wireless devices such as my iphone, ipad, laptop usually only get 6.5-8 mbps when testing speeds to the internet. I don't expect it to be as good as the wired due to interference, signal, etc. I don't get the choppy behavior however. Firware updates from Apple will appear in the same manner as standard software updates. If there is one available for your system it should appear when you check for software updates. That being said, I believe you can also manually download them from the Apple site.

How to know current speed of connection in Kbps?

Does anyone know how to know the speed of network/internet connection? I couldn't find any member method of JAVA's class that returns this value. Very appreciate for all your hints.

Try something like this:public class Test
public static void main(String[] argv)
    try
      URL url = new URL("http://java.sun.com"); /* put a pointer to some big image here */
      InputStream is = url.openConnection().getInputStream();
      int bytes = 0;
      long ms = System.currentTimeMillis();
      while(is.read() != -1) bytes++;
      ms = System.currentTimeMillis() - ms;
      double kbps = ((double)bytes / ((double)ms / 1000)) / 1024;
      System.out.println("kbps = " + (long)kbps);
      System.exit(0);
    catch(Throwable t)
      t.printStackTrace();
      System.exit(-1);
}I suggest you repeat this test for several pointers and take the average...

Slow Networking Speed

Hey,
I am getting some problem with the Internet on my virtual machine. I tested the speed with speedtest-cli tool, its showing me
Download: 26.03 Mbit/s
Upload: 13.28 Mbit/s
but the actual speed i am getting is :
100 - 200 kbps as downloading
and upload speed is also very slow.
how can i get the fast internet speed???
kindly resolve this issue.
Thanks in advance.

Hello Hemant Thakur,
1. What is the size of the Virtual machine that you have deployed on Azure?
There could be several reasons that the VM has a network performance issues. To check if there are any issues on the platform end, I suggest that you try the steps below:
I suggest that you restart your Virtual Machine to see if it makes the difference. You can do this by logging into your Virtual Machine or from the Azure Management portal.
If this does not work, I suggest that you resize your Virtual Machine. You can refer to the link below that will give you information on how to accomplish this:
https://msdn.microsoft.com/en-us/library/dn168976(v=nav.70).aspx
If these steps do not work, we might have to further invertigate this issue. I suggest that you create a Support ticket with us. You can follow the link below to create a Support ticket:

How to measure transfer (speed) of internet connection with TC

Hi
How can I find out how quick I surf the net with Time Capsule. Are there any opportunities in the setting to boost speed?
Thanks,
MF

Speed can be measured through the normal web apps that test your internet speed.
Frankly, unless you have 100mbit fibre the rate determining step is going to be the internet. For now and a long time to come. So measuring speed on your local network is irrelevant to web speed.
The utility Activity Monitor shows network speed, and I am sure you can download other meters that will average speed over longer periods. But I find the activity monitor is adequate for what I need.
Boost speed.. sure.. use ethernet.. do not use wireless. Make sure you are linked at gigabit.
For wireless if you are close to the TC force the wireless to 5ghz. This usually requires that you setup TC wireless with a different name for 5ghz band than 2.4ghz. In the same room 5ghz should be twice the speed of 2.4ghz or better.. but the advantage will drop off quickly.. so you need to locate equipment nearest where you use it.

Network speed issues while using osx

this may seem a little bit strange, and i can't make any sense out of it but if anyone can figure out what my problem might be it would be greatly appreciated.
i have an older duel os (win xp, leopard) mbp and have had a lot of problems with hardware/software (osx) in the past, and have ended up, to my dismay, almost exclusively using windows.
anyway, just yesterday i decided it was time to give osx another chance. so besides having it hanging constantly while doing simple tasks, i have noticed my network speed is drastically reduced.
i ran a test on speedtest.net and ended up with 500kps average download speed, and 70kbps upload speed, with the closest server in my town at 800 ping.
i straight away restarded into windows and ran the test again, and achieved 13500kbps download, and 600kpbs upload, with a ping of 66.
NOTHING changed between the time of restarting. The router was left as it was, no other computers are switched on, and nothing is downloading.
In the past when using osx i have had frequent connection dropping issues, but as i run wireless i always just attributed it to my router. Although since using windows exclusively this has also ceased.
I have looked through airport settings and cannot find anything that looks like it may be the problem, although i'm not as experienced at getting into the back-end settings on osx.
the part that confuses me the most is the ping. latency generally increases with distance, not so much speed. i dont understand how the same server situated nearby can give 66 ms in windows and 800 in osx.
if anyone has any ideas, i thank you in advance.
p.s. i have osx 1.5.4 and was updating to 1.5.5 but the slow download speeds caused me to create this post. it does mention an increase in network performance in update notes for 1.5.5, if that will solve this than i apologize, although i doubt this drastic speed difference could have existed for so long if everything is set up correctly.

You are certainly not alone. I have the same problem. Download speed seems to be limited to 500KB/s (any program, any service) and 2.18MB/s using Windows. I tried two different routers with the same results. Even downloading the same files using rapidshare led to this. Very strange.
This has nothing to do with the DNS server. My connection speed is pretty fast. With and without the recommended OpenDNS server settings. I just re-installed Leopard and updated to 10.5.6. Nothing changed.
Seems like something is throttling the max. dl speed. Odd!
