Any papers on how to calculate how many LIOs a query should use? For example I had a full table scan of a 1 MB table with 8kb blocksizes. The table was in memory, so no additional LIOs for hitting the storage. How do I calculate how many LIOs I should get? I actually go 63? Same for different types of index reads? Not an absolute necessity. I'd just like to know. Or maybe we can discuss it on here? ---------------------------------------------------------------- Please see the official ORACLE-L FAQ: http://www.orafaq.com ---------------------------------------------------------------- To unsubscribe send email to: oracle-l-request@xxxxxxxxxxxxx put 'unsubscribe' in the subject line. -- Archives are at //www.freelists.org/archives/oracle-l/ FAQ is at //www.freelists.org/help/fom-serve/cache/1.html -----------------------------------------------------------------
