I made complex select using PGAdmin III Query Editor, Postgre server 9.3
select ... from mytable join .. join ... order by .... I get [Total query runtime: 8841 ms. 43602 rows retrieved.] but when I use copy ([same above select]) to '/x.txt' I get [Query returned successfully: 43602 rows affected, 683 ms execution time.] these test made on the same machine as the postgresql server. can anyone explain huge difference in executing time? best regards all -- View this message in context: http://postgresql.nabble.com/Copy-command-Faster-than-original-select-tp5836886.html Sent from the PostgreSQL - performance mailing list archive at Nabble.com. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
