Hello, everybody recently I have found that queries on our customer database take longer to execute than normally. First thing we did was to log long queries. This led to nothing as queries logged are usually executed fast. On the other hand sometimes they take considerable amount of time... Then we tried using EXPLAIN ANALYZE - that brings me to the question: "Total runtime" of the query provided by the EXPLAIN ANALYZE is 0.200ms, but the result of it comes after sometimes 0.2, sometimes 5 seconds. We use pgAdmin tool to query the DB - it shows how long the query took to execute. The question is why the difference of value provided by EXPLAIN ANALYZE and observed one is so big? I know explain analyze has its overheads, but query itself takes long to execute. Also we've checked if the internet traffic is not too high - it appears not even close... Now I have run out of ideas what to check... Can you give me a hint what else can cause such behavior ? Thank You in advance.] Julius Tuskenis -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
