This will depend on what the information is to be used for.

Min is 0.0 and max is (total number of CPUs) *1.1 or *1.15
ie:
min 0.0 max 1.1 (1 cpu)
min 0.0 max 2.3 (2 cpu)

Your mileage may vary.

RAND(3) 								 1								   RAND(3)

rand - Generate a random integer

SYNOPSIS
int rand (void ) DESCRIPTION
int rand (int $min, int $max) If called without the optional $min, $max arguments rand(3) returns a pseudo-random integer between 0 and getrandmax(3). If you want a random number between 5 and 15 (inclusive), for example, use rand(5, 15). Caution This function does not generate cryptographically secure values, and should not be used for cryptographic purposes. If you need a cryptographically secure value, consider using random_int(3), random_bytes(3), or openssl_random_pseudo_bytes(3) instead. Note On some platforms (such as Windows), getrandmax(3) is only 32767. If you require a range larger than 32767, specifying $min and $max will allow you to create a range larger than this, or consider using mt_rand(3) instead. PARAMETERS
o $min - The lowest value to return (default: 0) o $max - The highest value to return (default: getrandmax(3)) RETURN VALUES
A pseudo random value between $min (or 0) and $max (or getrandmax(3), inclusive). EXAMPLES
Example #1 rand(3) example <?php echo rand() . " "; echo rand() . " "; echo rand(5, 15); ?> The above example will output something similar to: 7771 22264 11 SEE ALSO
srand(3), getrandmax(3), mt_rand(3), random_int(3), random_bytes(3), openssl_random_pseudo_bytes(3). PHP Documentation Group RAND(3)
