Hello, I think i have made a mistake about the follwing reader-writer lock of Joe Duffy: http://joeduffyblog.com/2009/02/20/a-more-scalable-readerwriter-lock-and-a-bit-less-harsh-consideration-of-the-idea/ Since a cache-line transfer between cores is not at all expensive, so the serial part of the Amdahl's law for this reader-writer above will still be smaller with more and more cores, so this will make this reader-writer lock above of Joe Duffy really scalable on read-mostly scenarios. Thank you, Amine Moulay Ramdane.
