Testing the application performance / speed

This article describes three tests which will help determine whether the experienced issues with slow loading times have to do with Nmbrs itself or whether the reason may be found elsewhere. It also shows you how to read the results and what the corresponding next steps are.

  1. The speed test measures the speed of your internet connection.
  2. The loading test checks to see if the Nmbrs loading time deviates from the standard Nmbrs loading times.
  3. The internal performance check shows the values of the CPU and the memory usage of your computer.

 

Please note: 

  • First, check the System requirements for Nmbrs.
  • Run these tests only if you are truly experiencing issues with the performance.
  • If you work in a Citrix, Multrix or Terminal Services environment, you may not be authorised to carry out all tests. In that case, ask your system administrator to do this for you.

1. Speedtest

If you have the impression that Nmbrs runs slower than usual, you can run the speed test. This test is used to determine whether this is caused by a slow internet connection.

Go to the speed test and click on 'Start Test':

 

Speed test results
Check the 'Download Speed'. The image below shows a download speed of 66.80 Mbps:

 

If the download speed is less than 20.00 Mbps and/or the ping is greater than 30ms, your internet connection may be too slow for Nmbrs to function properly. This explains why you feel that Nmbrs is running so slowly.
Unfortunately, we are not able to help you further with this issue. We do advise you to contact whoever is responsible for your internet connection, for example, your IT-department. A possible solution may be found based on the results of the speed test.  

If the the download speed is greater than 20.00 Mbps and/or the ping is less than 30 ms then we can conclude that the internet speed is sufficiently high and therefore this cannot be the reason for the experienced poor performance with Nmbrs. In that case, take a screenshot of the speed test and proceed to the loading test.

2. Loading test

The loading test can help to determine if the Nmbrs loading time is actually lower than the standard for Nmbrs. Go to the environment/dashlet where you experience a slow loading time.

For Windows (use Google Chrome for the loading test)

Step 1: Press the F12 key on your keyboard. Click in the resulting panel on the 'Network' tab (1).

Step 2: Press F5 and as soon as the page has finished loading, immediately (!) check the loading time next to 'Finish'(2):

 

For Mac  
Step 1: Click the right mouse button and then select 'Inspect':

 

Step 2: Click in the resulting panel on the 'Network' tab and then press '⌘ R' to reload the page:

Step 3: Check the loading time next to 'Finish':

Loading test results   
If the measured loading time is less than 15 seconds we can conclude that the loading time does not exceed the usual loading time for Nmbrs.  

If the measured loading time is greater than 15 seconds we can conclude that the loading time probably exceeds the usual loading time for Nmbrs. In that case, take a screenshot of the entire page, including the 'Finish' time, and proceed to the internal performance check.

 

3. Internal performance check

The internal performance check gives insight into your computer's performance.

For Windows  
Use the Ctrl+Alt+Delete key combination to open the 'Task Manager'.
Then check the 'CPU' and 'Memory' percentages:

For Mac:
Step 1: Go to 'Applications' and browse through the list of applications. Double-click on the 'Utilities' file and then on 'Activity Monitor' to start up the programme:

Step 2: Check the 'CPU' and 'Memory' percentages. For both the CPU and the Memory percentages, add together the 'System' and the 'User' percentages. The CPU percentage in the example below (40.45 + 23.70) is 64.15:

 

Internal performance check results
If the CPU and/or Memory percentage lies between 80 and 100 we can conclude that your computer is so overloaded that it has a negative effect on its performance.
There are numerous ways of dealing with this issue. Seeing as this is not a Nmbrs-related issue, you can contact your own IT department to have this resolved. You can also find some tips here (Windows) or here (Mac)

If the percentage of both the CPU and the Memory is lower than 80 we can conclude that your computer is not overloaded and that this cannot be the reason for the experienced slow performance. In that case, take a screenshot of the percentages and submit a request for the support department together with the screenshots you have made earlier.
