Google Chrome Silverlight Performance Is Significantly Slow

Google Chrome Silverlight Performance Is Significantly Slow

Chrome Silverlight rendering is very slow (estimation: 10 times slower) comparing to firefox and internet explorer. You can test this simply using following sample code. Sample code demonstrates 15000 random data rendering inside a data grid.

Do you have any opinion why this is happening? There are 2 speculations came to my mind.

1. Google does not want Microsoft's Silverlight gather wide usage on their platform.
2. Chrome's infrastructure somehow causes plugin rendering slow.

XAML part:

Merhaba,

A couple of days ago I encountered a msdn page. It says for Silverlight support x64 just for IE. Safari and Chrome browsers supported as x86. As a result of that you are right. Beside this AFAIK firefox has not a x64 setup.

But for Silverlight 5 things may changed.

I offer IE, Microsoft also :)

1. Google does not want Microsoft's Silverlight gather wide usage on their platform.
   A: From my experience, this is not a problem on Google side. I had same problem as you describe for a couple weeks before I sent an email to Microsoft support and they suggested me to use IE. They did not answer me why it works so slow on Chrome.

2. Chrome's infrastructure somehow causes plugin rendering slow.
   A: Again, this is not true at all. This problem comes from Microsoft. It seems like it does not care about Silverlight anymore. We plan to move our product to ASP.NET MVC for this reason too.
