Jonathan
DB version : 10.1.0.5
System stats are gathered by Oracle's default job which runs in the default
window.
Thanks

Are you running 10.1 or 10.2
Have you gathered system stats, or do you let
Oracle set the noworkload values on startup.
If the latter,
Have you set the db_file_mulitblock_read_count
If not,
What is the value of "processes"
What was the size of the db_cache at the time the
queries were optimised
