Hi Evgeniy,
You'll probably want to start by looking at my Linux Plumbers slides presenting rculfhash:
https://www.efficios.com/lpc2011-urcu
Also, Paul McKenney's slides of the Userspace RCU tutorial here present other numbers of a hash table example (including bucket-locks), AFAIK using his own statically sized hash table implementation (not rculfhash):

Thanks,
Mathieu

Hi,
I'm very interested in RCU performance, especially applied to hash
tables (rculfhash in particular). Did any body compare performance of
QSBR or signal RCU VS scalable and non-scalable spin locks?
