I want to rebuild all of the threads.

And it does matter.
On my forum, rebuilding the similar threads takes over 24 hours.
And the process often just dies somewhere at 25,000 threads.
If I start at the end, I can rebuild the similar threads for those latest threads and do not have to worry about the process reaching the oldest threads.
