ASP.NET Data Binding Performance – Collection Is More Expensive Than Datatable

Hello Alik,

If you casting DataItem in DataBound event and fill each line control (cells/labels), wouldn't you have a better performance?

Regards,

Something is wrong on your own numbers:

- the 1st one (customecollection) shows 0.0043

- the 2nd one (datatable) shows 0.0047

So the 2nd one is slower.

Hi, Israel!

Interesting remark.

Look at what PAG says about that:

http://msdn.microsoft.com/en-us/library/ms998549.aspx

look at "Minimize Calls to DataBinder.Eval" in it

I guess I need to do more testing - thansk for calling this out!

Anatoly,

Good catch! Please notice that in the post i measure how long does it take to DataBind() to complete and not the whole cycle as you call out. I must admit I was not that clear and this might have misled you. Sorry about that.

The other stuff. My main goal - which is also not very clear in my post - to identify CPU killers and I am less interested in response times.

Bottom line - you bring in interesting angle which adds to the whole picture, thank you for that
