|
| -# Test plan:
|
| -#
|
| -# If auto-vacuum is enabled for the database, the following cases
|
| -# should show performance improvement with respect to 3.3.17.
|
| -#
|
| -# + When deleting rows that span overflow pages. This is faster
|
| -# because the overflow pages no longer need to be read before
|
| -# they can be moved to the free list (test cases speed3-1.X).
|
| -#
|
| -# + When reading a column value stored on an overflow page that
|
| -# is not the first overflow page for the row. The improvement
|
| -# in this case is because the overflow pages between the tree
|
| -# page and the overflow page containing the value do not have
|
| -# to be read (test cases speed3-2.X).
