The point I'm trying to make is that if tweaking generic.h improves performance then it's an indicator of missed cases in the less-generic atomics code, and the latter is where our attention should be focused. I think basically all of the improvement Sokolov got was from upgrading the coverage of generic-gcc.h. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
