Deft server (Java) beats Node.js and Tornado

Server just appears to be overloaded - the status code it returns for the page is 503. It also tries to load some js/css but those return empty 503s.

In the meantime, Google returns this article about it: http://www.infoq.com/articles/deft-loft

They should change to a more performant web server, maybe something like deft.

The page just says deft for me, but apparently the project is in incubator over at apache: http://incubator.apache.org/deft/

This would be far more interesting if Netty was in the comparison.

"Tornado and Node.js are the two other asynchronous web servers that we used in the benchmark. We didn't include Netty because it felt a little bit like comparing apples with oranges. But I wouldn't doubt if Netty showed numbers equal to (or greater?) the results we have seen for Deft. Netty, the successor to apache mina, is a really cool socket framework written by a really smart guy (Trustin Lee)."

And it also happens to be really fast. I don't want to compare my framework to something that can be really performant.

And?

The example code shown does nothing that Netty can't do without using any external "frameworks".

So, first of all this is hosted on Google App Engine -- so I don't even see how it could even provide what is claimed. The environment doesn't really support it.

If you want asynchronous network programming in Java or Scala, you should be using either Netty or something higher level like Finagle: http://github.com/twitter/finagle

Awesome, look at that scale... Ohh what's that, returning 503.

This is probably the most amazing thing I've seen in a long time: http://i.imgur.com/sBMCW.png

article doesnt open for me just a blank page with word 'deft'? is this some retard post with no content or is the server overwhelmed?

Why the downvote? Did the word retard offend you?

I wasn't the downvoter, but yes, the word retard does offend me. Why do you use it in this context?

I'd assume classes of web app servers perform roughly the same. An evented server in C(++) (Nodejs) should be faster than an evented server in Java for small app code request handlers.

For larger app code the speed should approach the performance ratio of the VMs (V8/JVM) involved.

So I think this is rather uninteresting.
