My apologies. The inserts in the above tests were made on a TEMP table which I assumed was being created in the existing database. I've since discovered that isn't the case.*Tables created using the "CREATE TEMP TABLE" syntax are only visible to the database connection in which the "CREATE TEMP TABLE" statement is originally evaluated. These TEMP tables, together with any associated indices, triggers, and views, are collectively stored in a separate temporary database file that is created as soon as the first "CREATE TEMP TABLE" statement is seen. *Running the same tests again using an actual table (TEMP keyword omitted) shows the in memory INSERT (and DELETE) to be twice as fast on the database loaded into memory compared to when it's accessed from the SSD.The timings in the original tests were similar to the in memory database suggesting the TEMP table for those tests were created in memory regardless of whether the actual database was loaded in memory or not. I can't see any documentation suggesting that though. Could someone clarify?
