Hi all,
    I have some question about Sqlite cache:
    1.  In the Sqlite docs, It's said :" If you are doing
UPDATEs<http://www.sqlite.org/lang_update.html>or
DELETEs <http://www.sqlite.org/lang_delete.html> that change many rows of a
database
        and you do not mind if SQLite uses more memory, you can increase the
cache size for a possible speed improvement."
        Why only UPDATEs <http://www.sqlite.org/lang_update.html> or
DELETEs<http://www.sqlite.org/lang_delete.html>? Does INSERTs or
SELECTs  speed have no relationship with Sqlite cache?
    2.  Cache was malloced in a transaction, and was freed at the end of a
transaction, is right?
    3.  Please intrduce the implement of cache mechanism in Sqlite.

    Thanks very much!
      Yoky
