$ go get -u -v -x


Note that all of this benchmarks have been implemented as his owners recommends. More of this goroutine pools works with more than 4 goroutines.

After a lot of benchmarks and the following enhancings of the package I got this results:

type Pool

type Pool struct {
	// contains filtered or unexported fields

Pool slaves

func NewPool

func NewPool(workers int, w func(interface{})) (p Pool)

NewPool creates SlavePool.

if workers is 0 default workers will be created use workers var if you know what you are doing

func (*Pool) Close

func (p *Pool) Close()

Close closes the SlavePool

func (*Pool) Serve

func (p *Pool) Serve(w interface{})

Serve sends work to goroutine pool

If all slaves are busy this function will stop until any of this ends a task.

func (*Pool) ServeNonStop

func (p *Pool) ServeNonStop(w interface{}) bool

ServeNonStop returns true if work have been sended to the goroutine pool.

This function returns a state and does not block the workflow.
