Async Nodejs

M dHatter

Got my new custom async Nodejs webserver running. I tested it with Jmeter and it shows about 41,000 connections a second with no error. Seems pretty fast for a slow ass dev server. I notice the Jmeter is using 65% cpu and nodejs is about 15% to 30%. There is still room for improvement. I would like to get to the 100k connection level for one machine. One can only dream... :wtf: I'm actually impressed what this V8 engine can do.

What is this all about ?! :confused:

I think words like 'destiny' are a way of trying to find order where none exists. - Christian Graus Entropy isn't what it used to.

It was broke, so I fixed it.

You're a power-load ;P

Enough to drive you nuts. :)

The V8 engine is only part of the story, I think the non-blocking event nature of node.js probably has more to do with it.

Errrm what? Node is async by default.

M dHatter

Actually its both sync and async depending on the code you use.

I still haven't fully wrapped my head around Node.js. Is it supposed to allow people to code things in JavaScript outside of a browser, a bit like how Adobe's Flex crap works?

Pete OHanlon

Yes. I like it a lot.

M dHatter

It's a whole new world of spaghetti goto code. But its fun :-\

Well good. Fun is fun. I like fun. It's fun and all.

It's all fun and games until you hit the database :sigh:

I'll have to find an excuse to check it out then.

Surely it's a whole new world of requires and module.exports.

Whenever I've put it head to head with async asp.net on similar hardware asp.net has ended up with about twice the performance or more. It's much easier to just throw stuff together in node though, and meteor was pretty awesome the last time I played around with it.

We are building a production system for Nodejs relational data service (front) layers right now. From what we are getting, it seems to be good at present. Of course we haven't done any performence comparision yet.

Our problem was using database drivers. Most are not designed to handle async event load. We switched to mongo, which seems to work better, but it's hard to say without large data to test with. If you want to bounce any ideas around message me. Latez :-D

just a silly question... why use nodejs when you can use webapi and such like? It's not a rhetorical question, I don't like JS.. :~ though I am getting used to it slowly.. but I couldn't fathom using it in place where there are perfectly working other solution, wondering what might cause other people to do the jump! Speaking of which, javascript joke, what is the value of this?
