threshold of what?

The raw value only tells you how busy it is, not how busy it should be. It's more useful for comparison. Sudden, unexpected changes can be indicative of problems.

Once it gets above 1 I'd call the machine very busy, and above 2 I'd call overloaded, but ymmv. You can tune a machine to work well even under high loads.

SYNOPSIS
void sqlite_busy_timeout (resource $dbhandle, int $milliseconds) DESCRIPTION
Object oriented style (method): void SQLiteDatabase::busyTimeout (int $milliseconds) Set the maximum time, in milliseconds, that SQLite will wait for a $dbhandle to become ready for use. PARAMETERS
o $dbhandle - The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the object-oriented method. o $milliseconds - The number of milliseconds.

No value is returned. EXAMPLES
Example #1 Procedural style <?php $dbhandle = sqlite_open('sqlitedb'); sqlite_busy_timeout($dbhandle, 10000); // set timeout to 10 seconds sqlite_busy_timeout($dbhandle, 0); // disable busy handler ?> Example #2 Object oriented style <?php $dbhandle = new SQLiteDatabase('sqlitedb'); $dbhandle->busyTimeout(10000); // 10 seconds $dbhandle->busyTimeout(0); // disable ?> SEE ALSO
