The document describes a test that was run to determine if the contiguity of table extents impacts performance. The test procedure created tables with contiguous and discontiguous extents in different tablespaces and measured the time to select and delete records. The results showed little performance difference between contiguous and discontiguous extents, between large and small extents, or between dictionary-managed and locally managed tablespaces. On average, selecting records took around 2-3 seconds and deleting records took around 45-55 seconds, with no significant performance impacts from extent contiguity.
