The way bbPress does recounts is horribly bad to this very day, even in 1.0

https://trac.bbpress.org/ticket/1146

It does a separate query for every topic instead of doing it all internally via mysql.

Be sure to only do one kind of recount per attempt, don’t check them all on an active forum or you’ll make your mysql cry and your php timeout.

I might have to try to write the special mysql query for you.
