Try out the kick-starting section about uwebsockets.js

Yeah I need to check this out. Too bad Apple computers are priced in a way that it makes no logical sense to ever buy them. At least the Swedish prices are simply unreal - 125% or 150% that of US prices.

Like... who the actual fuck wants to buy the new Macbook air for 15000 SEK that's like the price of four stolen cars. You can have much more joy with four stolen cars I tell you...

My gaming computer cost me 8000 SEK and it has a fucking geforce 980 as big as my thigh... and they want me to buy fucking integrated intel graphics for 15 thousand SEK wtf

Ah, lol.. I haven't even updated the Makefile since.. ever

[goriunov]

Agree :) Unfortunately my work place has another opinion so they provide macbooks to everyone.

I have WMware at home.. will fire that shit up when I can

@tleasure those numbers seem very reasonable. On Linux I get multiple times better IO compared to Node.js,

But on macOS it seems like the difference is not all that great - can macOS people try and compare the IO of hello world with nodejs?

Maybe it's just Linux being a lot more efficient than macOS as a system (wouldn't surprise me at all)?

Yeah that's the same error I have heard about before. Something is wrong with the macOS build.

[andymans]

Yep. Am on node 11.1.0 on OSX High Sierra. Getting same error as @goriunov. Will try it also on Linux (Alpine under Docker) as it's quite a popular deployment option, and report any issues (if any) with that env.

Maybe it works now, maybe not

Alright, should be close to working now. This code only works with Node.js 10 and 11

[kevlened]

$ node -v
v11.1.0
$ node examples/HelloWorld.js
Segmentation fault: 11

$ node -v
v10.10.0
$ node examples/HelloWorld.js
Segmentation fault: 11

👌

If you change the HelloWorld.js to only this:

var uWS = require('../dist/uws.js');
console.log(uWS);

Does it print { App: [Function], nextTick: [Function] }?

Does uWS.App(); work?

[goriunov]

@alexhultman it does not go farther than

const uWS = require(`./uws_${process.platform}_${process.versions.modules}.node`);

I have tried running

module.exports = (() => {
	try {
		console.log("1");
		const uWS = require(`./uws_${process.platform}_${process.versions.modules}.node`);
		console.log("2");

		/* We are not compatible with Node.js domain */
		// console.log(uWS);
		process.nextTick = (f, ...args) => uWS.nextTick(f.apply(...args));
		return uWS;
	} catch (e) {
		console.log("3", e);

		throw new Error('This version of µWS is not compatible with your Node.js build.\n\n' + e.toString());
	}
})();

and got output:

Dmitriis-MacBook-Pro:uWebSockets.js dmitrii$ node examples/HelloWorld.js

Segmentation fault: 11

[goriunov]

I have done some small checks it seg fault comes from uWS_App method if i comment

 uWS::Loop::defaultLoop()->setPostHandler([](uWS::Loop *) {
      emptyNextTickQueue(isolate);
   });

i can properly print:

{ App: [Function], nextTick: [Function] }

Then it should work. Just remove that nextTick thing (console.log will not print).

[goriunov]

Still have error/print even after removing nextTick. I have tracked seg fault to (not sure if i am aright though):

localApp->SetAlignedPointerInInternalField(0, new uWS::App());

// This one:
new uWS::App()

It runs on Linux and macOS now

[goriunov]

Working alright :)

[kevlened]

Works on mac for me too 💯

I've heard 90k req/sec vs. 52k on macOS yet on Linux you can see more like 120k vs. 20k. Let's see if this ratio difference is same for all

If you normalize spent CPU-time the numbers are a lot better. Basically it seems wrk does not stress the server fully on macOS for some reason, I only get up to 62% CPU time. You can also extra check this by running:

time node examples/HelloWorld.js and compare real-time with user space + system time and normalize by that.
