No, there is no caching implemented as that would potentially result in incorrect viewing permissions if the parent forums/threads changed.
As it checks viewing permissions for all threads and respects the original permissions of the forums/threads, it's expected that it will take some time to render the page with over 10,000 threads archived.
The archive was created for that reason - so the main home page can be kept to a smaller subset of featured threads, avoiding the extended rendering time.
