[sqlite] about compile configure

[王庆刚]

hi,all
       When we compile the sqlite source code, there are so many configuration, 
such as
       SQLITE_DEFAULT_FILE_FORMAT=4;
       SQLITE_MAX_ATTACHED=30;
       SQLITE_ENABLE_COLUMN_METADATA;
       SQLITE_ENABLE_FTS4;
       My question is that could different configuration influence the 
perfomance of the sqlite? and how it influence the performance?

       WQG
       best regards.
