Configure Database Performance / Robustness
Updated by Russell Samuels on Nov 13, 2014

MediaMonkey uses the SQLite database to store information. The SQLite database is by default configured to be very safe even in cases of software or hardware failure. However, some users might prefer to sacrifice a little safety and get slightly improved performance.

For such users, the line indicated below should be added to the [System] section of the MediaMonkey.ini file:

[System]
SQLiteSafety=x


Possible values for x are 0, 1 or 2:
0: fastest-least robust, also known as synchronous = OFF.
SQLite continues without pausing as soon as it has handed data off to the operating system. If MediaMonkey crashes, the data will be safe, but the database might become corrupted if the operating system crashes or the computer loses power before that data has been written to the disk surface. On the other hand, some operations are as much as 50 or more times faster at this setting.

1: medium-very robust, also known as synchronous=NORMAL.
The SQLite database engine will still pause at the most critical moments. There is a very small (though non-zero) chance that a power failure at just the wrong time could corrupt the database. But in practice, you are more likely to suffer a catastrophic disk failure or some other unrecoverable hardware fault.

2: slow-extremely robust (default), also known as synchronous=FULL.
With a value of 2, the SQLite database engine will pause at critical moments to make sure that data has actually been written to the disk surface before
continuing. This ensures that if the operating system crashes or if there is a power failure, the database will be uncorrupted after rebooting. This mode is very safe, but it is also slow.
