- node (whose main reason for existing is event driven IO) is in the same order of magnitude as nginx (whose main reason for existing is also event driven IO). I think sometimes people think node is ruby/python/php levels of performance. It isn't.

- And as another comment mentions, developer productivity may be better than minor performance difference - you mentioned Caddy, same rationale applies here.

- nginx is also a bit crippled as useful features (like dynamic reconfig) are only in the proprietary nginx plus.

- This has good defaults - having to set up the seperate webserver for ACME is a pain, this is way easier.

Python: we use the node event loop too now (https://magic.io/blog/uvloop-blazing-fast-python-networking/).

But actually, you could have setup a pure Python server instead of nginx for the last 10 years with twisted.

Not that you should not consider uring nginx anyway: it deals with caching, load balancing, has great tutorials, it's battle tested, and has tons of pluging.

But performance wise, WSGI is not Python.

Sure, I mentioned Tornado a few minutes before you posted this. Twisted obviously counts too, I dislike the non-PEP8 coding style it uses but that's off topic. I love Python's non blocking features, they're just not in the mainline VM right now. Here's hoping for a libuv or whatever else non blocking Python 4 VM / stdlib.

Asyncio has been in the the mainline VM for quite some time.

Yep, the stdlib just needs to use it. In nodeland blocking is the exception: that's not yet the case in Python.

Do you know of a performance benchmark that shows the current status? I can't find many that describe node not at those levels of performance, Especially against Ruby.

[nailer]

Sure: https://iwf1.com/apache-vs-nginx-vs-node-js-and-what-it-mean...

I haven't seen anyone compare Ruby to node perf, unless there's a non blocking variant of Ruby (looks like nio4r), in which case it would have similar perf.

Likewise node vs Python Tornado would be a good comparison.

Thing is, nio4r and Tornado aren't the standard library. Whereas node's stdlib is: node's file and socket read operations etc are non blocking, Python and Ruby equivs are not.

Also (addressing weird moderation - sudden downvotes when I mentioned other languages): please don't turn this into a lang tribal thing: I personally think Python is a better language than JavaScript, it just blocks by default. This isn't a matter of preference, it's a fact.

[rileymat2]

That resource looks like node is faster than those other languages? I think you might be getting the down votes because your comment is being interpreted that it is slower.

Except, it is ruby/python/php slow: https://www.techempower.com/benchmarks/#section=data-r17&hw=...

All of PHP, Ruby, and Python beat Node.js in the above-linked benchmark.

Raw number crunching performance is similar with Node and Go. Python and ruby are in different league than them. https://benchmarksgame-team.pages.debian.net/benchmarksgame/...

Do you think this discussion or the OP is about "[r]aw number crunching performance" ?
