Slow assertion of predefined objects

[Kauzig]

In my nools rule language file I have defined the following object:

define MyObject {
    id : '',
    value : 'NO_VALUE',
    parameters : { },
    constructor : function(id, value, parameters) {
        this.id = id;
        this.value = value;
        this.parameters = parameters;
    }
}

I have noticed that adding instances of these objects takes a notably long time. Executing the following testing code,

var _flow = this._nools.compile(noolsDSL, {name: "adaptationRules"});
var _MyObject = _flow.getDefined("MyObject");
var _currentSession = this._flow.getSession();

var addIntTime = Date.now() / 1000;
for (var i = 1; i < 10000; i++) {
    _currentSession.assert(i);
}
console.log("Add 10000 integers time: "+(Date.now() / 1000 - addIntTime));

var addStringsTime = Date.now() / 1000;
for (var i = 1; i < 10000; i++) {
    _currentSession.assert("foo");
}
console.log("Add 10000 strings time: "+(Date.now() / 1000 - addStringsTime));

var addArrayTime = Date.now() / 1000;
for (var i = 1; i < 10000; i++) {
    _currentSession.assert([1, 2, 3]);
}
console.log("Add 10000 arrays time: "+(Date.now() / 1000 - addArrayTime));

var addObjectTime = Date.now() / 1000;
for (var i = 1; i < 10000; i++) {
    _currentSession.assert({foo: "bar", baz: [42, "foobar", 24]});
}
console.log("Add 10000 objects time: "+(Date.now() / 1000 - addObjectTime));

var addDefinedObjectTime = Date.now() / 1000;
for (var i = 1; i < 10; i++) {
    _currentSession.assert(new _MyObject("foo", "bar", {foo: "baz"}));
}
console.log("Add 10 predefined objects time: "+(Date.now() / 1000 - addDefinedObjectTime));

produced these times for asserting different data types.

Add 10000 integers time: 0.06599998474121094
Add 10000 strings time: 0.06400012969970703
Add 10000 arrays time: 0.06499981880187988
Add 10000 objects time: 0.0690000057220459
Add 10 defined objects time: 7.391999959945679

Here are the times for individual objects:

Add predefined object time: 0.002000093460083008
Add predefined object time: 0.007999897003173828
Add predefined object time: 0.015000104904174805
Add predefined object time: 0.06499981880187988
Add predefined object time: 0.14400005340576172
Add predefined object time: 0.39100003242492676
Add predefined object time: 1.003000020980835
Add predefined object time: 3.2190001010894775
Add predefined object time: 4.48799991607666
Add 10 predefined objects time: 9.337000131607056

Seems to be an exponentially increase.

Further research did reveal that not the type of the object is the cause for the long assertion times, rather the following rule:

rule "4cde00e8-4118-46a5-815c-32ec47f76a9f" {
    when {
        c1 : MyObject;
        c2 : MyObject;
        c3 : MyObject;
        c4 : MyObject;
        c5 : MyObject;
        c6 : MyObject;
        c7 : MyObject c1.id == 'ID1' && c1.value == '127' && (c2.id == 'ID1' && c2.value == '124' || c2.id == 'ID1' && c2.value == '125') && (c3.id == 'ID1' && c3.value == '128' || c3.id == 'ID1' && c3.value == '125') && c4.id == 'ID2' && c4.parameters['P1'] == 'PV1' && c4.value < '20.0' && c5.id == 'ID3' && c5.value == 'FEATURE_PHONE' && c6.id == 'ID4' && c6.value == '13.13021' && c7.id == 'ID5' && c7.value == '52.39346';
    } then {
        emit("select", "126", facts);
    }
}
