Browser - Child objects method is very very slow

[prasperl]

I am using the below given step to collect all the child objects in a page.

it takes almost for minutes to collect 200 child objects.Is there any way to speed up this process?

Code:

Set odesc=nothing
Set odesc=Description.Create()
odesc("micclass").value="WebElement"
odesc("class").value=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Set l_link=Browser(xxxxxxxxxxx).Page(xxxxxxx).ChildObjects(odesc)
