First Query Always Takes More Time Than Subsequent Queries Executed Within The Same Connection in JDBC
(Doc ID 1333080.1)
Last updated on MARCH 08, 2017
Applies to:JDBC - Version 18.104.22.168 and later
Information in this document applies to any platform.
The first query, no matter its complexity (even select 1 from dual), seems to incur an additional ~300ms penalty.
select 1 from dual; <-- slow
complex query <-- fast
Second run with different order of queries:
complex query <-- slow
select 1 from dual <-- fast
Why is this behavior?
