This is the same value as before the Oracle update from 11g to 12c. For the complete list of troubleshooting steps, you can check here: Troubleshooting long running sessions. This tool uses JavaScript and much of it will not work correctly without it enabled. Serial statements are typically short running and any DS overhead at compile time can have a large impact on overall system performance if statements are frequently hard parsed. Learn more. So for my experiment: Statistically speaking 12c is faster at processing buffer gets than 11g. Both are stand-alone databases and the 12c is not a pluggable DB. We made traces of our Oracle 12c database activities during such a warehouse catalog save procedure. I've never played around with those particular parameters before.

    Parallel statements are generally more resource intensive, so it's often worth investing in additional overhead at compile time to potentially find a better SQL execution plan. What tool are you using to query? Admittedly, I am kind of taking the easy way out, on the off chance that someone might identify some small setting I might have overlooked.
