Hi !
Is there a solution to improve performances issues on $$ function under IE ?
On load I try to do $$(''.test'') on a big HTML (120kb) page and
it
takes 5 seconds !
Is there hidden tips or clues to did it better ?
If I specify a Tag like $$(''UL.test'') it is faster.
Unfortunatly I
can''t do that because I don''t know the tag using this class .
Best Regards

But does your page really have to be one of those?

Thanks, I gonna try getElementsByClassName() About 120Kb, I know ... It is a really big sample portal with many portlet so many XHTML ... In real life it should be lighter.
