BrowserField: Performance degradation after OS update to Version OS6 OS7

Hi,

I have a Java based OS5 native app to display a webpage (result from a reporting web application) in a net.rim.device.api.browser.field2.BrowserField.

 

After OS update to Version 6/7 the performance is very bad.

 

Here are the performance results:

 

Performance App

 

OS 5: 22 s (Bold 9700)
OS 6: 250 s (Bold 9700)
OS 7: 65 s (9800)

 

Performance Browser:

The remote call via a URL in the BlackBerry Browser.


OS 5: 22 s (Bold 9700)
OS 6: 50 s (Bold 9700)
OS 7: 30 s (9800)


Is there a way to speed it up the display of the result.

Thanks for your help!

Can we clarify your question using your worst case:

 

Are you saying that the same URL takes 50 seconds to load up on the Browser, but 250 seconds if loaded using the BrowserField2?

Yes, the same url takes 50 seconds to load up on the Browser, but 250 seconds if loaded using the BrowserField2.

And this is a standard BrowserField with no overrides of the configuration or protocol handler?

 

Is this a URL you can share?

Re: BrowserField: Performance degradation after OS update to Version OS6 OS7

The URL is a internal intranet link. We use the standard BorwserField without special configuration and protocol handler.

 

Here are additional information of the reporting web application according new performance measurements:

 

- Java based JEE web application (JSF)

- The 3 redirects in the web application are responsible for the poor performance -  the Blackberry Browser  and the BrowserField respectively in OS 6/7 have a problem with redirects - IMO

- The HTTP request from the BrowswerField reached in 2 seconds  the web application, the report execution takes only 2 - 3 seconds, the remaining time will be used for redirects and the rendering in the BrowserField
