Connection pool

By default this provider uses many connection to APNs for sending notifications which equals to number of available CPU cores. If in your use case it is to small or too big number, you can adjust it by setting value of pool-size configuration property. Setting it to 5 will make sure to use only five connections to APNs.

Example. 

push () {
    'apns-binary-api' () {
        'pool-size' = 5
    }
}
