Is there a simple way to check whether spin-locks are running native? All non-ancient versions of PG force you to say "configure --disable-spinlocks" to get a build without native spinlocks. Such builds are only considered suitable for zero-order port testing, because the performance hit is so bad. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
