Third Party controls UI Rendering Performance Results

As I was briefing in the my previous post on Evaluating UI performance / Rendering speed of controls, I ran tests on my machine against SDK Grid, Infragistics Xam Grid & Telerik Rad Grid and came up with below test results.

UI Rendering Performance Results

  • First time rendering is always slower on any of the Grids
  • Both SDK grid and Infragistics Xam Grid have similar load performance
  • Load Performance on all three grids is as # rows goes beyond 2 million
  • Telerik’s Rad Grid loads 4 – 7 times slower than rest for first 2 million rows

These test results my vary from machine to machine and hence I suggest you to test it for yourself using source or run the demo on your machine.

Stressing once again that I am in no way associated with any of the 3rd party control providers, I would like to bring up an important notes from my testing. The slow rendering performance (say 2-3 seconds) might be relatively invisible to end user when compared to delay in waiting to receive data from server to client takes long time (say 20-30 seconds).

Performance difference of 400% – 700% could be a minor one or really huge based on needs / how you view things. Should your application data is small & got users with some patience then showing the data grid with 400 millisecond slower might not count when considering the grid features that fits your needs. However, if your application is large enterprise app, where every layer in your app is facing some throttling, then every millisecond counts. Hopefully this post shed some light on UI control rendering performance and helps help you make a decision on controls that fits your needs.
