Hi all
There is no doubt, in fact it uses test_and _set, but it is still doing a
lot of semops, I send u and extract from another execution, it is 6 streams
of read-only queries+a stream of inserts and deletes(with 5 sec between each
stream)+a stream of vacuum on modified tables each 10 secs.
Thanks and regards
