Long delay in opening url in 5800

[3kworld]

hi everyone,
I'm using this piece of code to open an url from my application:

http://wiki.forum.nokia.com/index.php/TSS000340_-
_Launching_the_Web_browser_on_S60_3rd_Edition_to_open_a_specified_URL

It worked fine on 5800, but it has a long delay.
Can someone know this problem? Plz tell me how to make it faster.
