Thank you. I have merged it to master.
I refactored the project to using prototypes (branch default). When performing a prof run of 3000000 Queues the summary looks like this:
prototyping
[Summary]:
ticks total nonlib name
182 18.8% 36.7% JavaScript
300 31.0% 60.5% C++
51 5.3% 10.3% GC
471 48.7% Shared libraries
14 1.4% Unaccounted
Your class based solution have the following summary when running the same number of queues:

I have actually started in the default branch. The performance gain is immense!
Talk about misconception, I have avoided prototyping for some reason...
from smqp.

Thanks! We have seen the results and they are way better. We have a version with even better results. We are working on it and we will do a PR when it's ready
from smqp.

how about if we change it to getters and setters?
from smqp.

or is that basically the same...
from smqp.

with getters these properties are enumerable, and if you do any Object assign, stringify... you are seen this "private" properties and use them too. With symbols, or making a prototype, you can avoid this, but it needs a big refactor
from smqp.

We did this change in the Message.js file:
import { generateId } from './shared';
export { Message };
const messageIdSymbol = Symbol.for('messageId');
const ttlSymbol = Symbol.for('ttl');
const pendingSymbol = Symbol.for('pending');
const consumedCallbackSymbol = Symbol.for('consumedCallback');
const consumedSymbol = Symbol.for('consumed');
const onConsumedSymbol = Symbol.for('onConsumed');
const publicMethods = ['consume', 'ack', 'nack', 'reject'];
function Message(fields = {}, content, properties = {}, onConsumed) {
if (!(this instanceof Message)) {
return new Message(fields, content, properties, onConsumed);
}
this[onConsumedSymbol] = onConsumed;
this[pendingSymbol] = false;
this[messageIdSymbol] = properties.messageId || `smq.mid-${generateId()}`;
const messageProperties = { ...properties, messageId: this[messageIdSymbol] };
const timestamp = (messageProperties.timestamp =
properties.timestamp || Date.now());
if (properties.expiration) {
this[ttlSymbol] = messageProperties.ttl =
timestamp + parseInt(properties.expiration);
}
this.fields = { ...fields, consumerTag: undefined };
this.content = content;
this.properties = messageProperties;
for (let i = 0; i < publicMethods.length; i++) {
const fn = publicMethods[i];
this[fn] = Message.prototype[fn].bind(this);
}
}
// These assignations are called only once
Object.defineProperty(Message.prototype, 'messageId', {
get() {
return this[messageIdSymbol];
},
});
Object.defineProperty(Message.prototype, 'ttl', {
get() {
return this[ttlSymbol];
},
});
Object.defineProperty(Message.prototype, 'consumerTag', {
get() {
return this.fields.consumerTag;
},
});
Object.defineProperty(Message.prototype, 'pending', {
get() {
return this[pendingSymbol];
},
});
Message.prototype.consume = function({ consumerTag } = {}, consumedCb) {
this[pendingSymbol] = true;
this.fields.consumerTag = consumerTag;
this[consumedCallbackSymbol] = consumedCb;
};
Message.prototype.reset = function() {
this[pendingSymbol] = false;
};
Message.prototype.ack = function(allUpTo) {
if (!this[pendingSymbol]) return;
this[consumedSymbol]('ack', allUpTo);
};
Message.prototype.nack = function(allUpTo, requeue = true) {
if (!this[pendingSymbol]) return;
this[consumedSymbol]('nack', allUpTo, requeue);
};
Message.prototype.reject = function(requeue = true) {
this.nack(false, requeue);
};
Message.prototype[consumedSymbol] = function(operation, allUpTo, requeue) {
[
this[consumedCallbackSymbol],
this[onConsumedSymbol],
this.reset.bind(this),
].forEach((fn) => {
if (fn) fn(this, operation, allUpTo, requeue);
});
};we have tested this code:
const {Message} = require('../dist/src/Message');
const nIteration = 3000000;
for (let i = 0; i < nIteration; i++) {
Message();
}And the results of the node --prof are very promised:

We tried to maintain the same external contract for the Message function and returned object, and all the test are working.
If you like the change, we can prepare a PR with this applied in every function

Not sure why but recent version of smqp has also big impact on memory consumption.
Before:
- when hundred of bpmn engine instances were created it took more than 3GB of memory
Now (after upgrade):
- when hundreds of bpmn engine instances were created it seems to run normally

That’s great!
Not entirely sure why prototyping has this effect. But the number of LazyCompiles decline a lot when compared to the closure version. Since object creation is expensive I guess that precompiled “classes” renders objects faster. Much faster. Kind of makes sense. Sorry for not realizing this earlier. And thank you to the owners of this issue.

@roberto-naharro and I have been working on more optimizations, they are available in #6
Kindest regards!

There shouldn't be such a big difference, both version are doing basically the same (class is just syntax sugar to assign to the prototype typing a little bit less) 🤔
I wasn't aware that you had already finished all the optimizations using the prototypes, we were trying to save you some work with this one 😅

Sorry for the double work. You could check that you receive the same profiling result on your end. I tend to get things wrong.

No problem at all, it was nice to get some extra insights :D
I tested with Message and your branch is 9% faster 👍

The Message.js is all yours. Ctrl+c+v. :)

Now I have exhausted the possibility of using WeakMap and other perf tweaks but nothing has proven to be faster or less CPU intense than the current solution. Prototyping with symbols seems to be the best solution. Over and out.
