Hi All;

I'm looking for tips / ideas per performance tuning some specific queries. These are generally large tables on a highly active OLTP system (100,000 - 200,000 plus queries per day)

First off, any thoughts per tuning inserts into large tables. I have a large table with an insert like this:

insert into public.bigtab1 (text_col1, text_col2, id) values ...

QUERY PLAN ------------------------------------------
 Result  (cost=0.00..0.01 rows=1 width=0)
(1 row)

The query cost is low but this is one of the slowest statements per pgfouine
Do you insert multiple values in one transaction, or one transaction per insert?
