Method Detail

ioIntesivePoolSize

public static int ioIntesivePoolSize()

Each tasks blocks 90% of the time, and works only 10% of its lifetime. That is, I/O intensive pool

Returns:

io intesive Thread pool size

poolSize

public static int poolSize(double blockingCoefficient)

Number of threads = Number of Available Cores / (1 - Blocking Coefficient) where the blocking coefficient is between 0 and 1. A computation-intensive task has a blocking coefficient of 0, whereas an IO-intensive task has a value close to 1, so we don't have to worry about the value reaching 1.

Parameters:

blockingCoefficient - the coefficient

Returns:

Thread pool size
