Webgrid performance in prerender

For improving WebGrid’s server performance, we recommend you to set the value of ViewStateStorage property to “None”, which result in best performance.

Our WebGrid development team said that there is binary serialization process in the middle of pre-render event that cost our head time. The team has contacted Microsoft for this matter. It is confirmed that the process is being handled by .NET Framework. Due to the information that I got from our dev team, the Microsoft team said that it will be enhanced in .NET Framework 4.0.

Hope this help.

Hi Yudi,

Yes, that pretty much the behaviour we are seeing. And if you put more grid instances on the page, you'll see the time in pre-render increases.

We want to know from Intersoft, is this a performance bug in the grid? And is there a workaround?

Thanks

I enclosed the screenshot of the trace result of a single WebGrid on a page. It was taken from PC with Microsoft Windows Server 2003 R2 Enterprise Edition Service Pack 2. The build version of WebGrid 7.0 is 306 and WebUI.NET Framework 3.0 is 705.

I followed carefully the steps that you describe in the previous post. On the initial load of WebGrid page, it will load scripts, styles, etc; it takes 0.4 second on the pre-render. But after I refresh the page, it only takes 0.2 second for the pre-render.

Hope this help.

Hi Yudi,

It is happening on Windows 2003 SP2 Server 32bit when deployed to a test server running under IIS.

Also same thing happening on the development machine running Windows Vista 64bit under the development web server.

To reproduce, just create a blank ASP.NET web application, put the grid on a blank aspx page from the designer, enable tracing and you'll see the performance issue.

Thanks

We need to check and test this issue for further investigation.
Could you please provide us any useful information about your test environment, such as whether it’s development or deployment environment; the version of the operating system; is it 32-bit or 64-bit operating system; etc.

Thank you.

Hi,

We are having performance issue with the WebGrid.

On a brand new clean web application project, just by putting the WebGrid on the page causes the page to slow down in the PreRender process.

See trace below, the PreRender step uses .41 second, and this is an empty page, with just the WebGrid on the page with default settings.

We've done some testings, and it seems that it doens't have this issue if we change ViewStateStorage to "None", but want to know is it expected to be this slow with the default settings of "Client" for ViewStateStorage. The speed also decreases with more instances of the grid on the page, eg if we have two grid on one page, the speed slows to .8 seconds.
