I mentioned it in another topic regarding kbin, which is also written in PHP.
If you run a node/go/rust server and you hit the endpoint
/hellowhich returns a simple "hello world", they will just return that. PHP however, has to initialize and execute the whole framework stuff, before returning a simple "hello world".So there's definitely some overhead, which to some degree can be limited by using caching like redis, etc.
I can follow that. I think most applications that keep running ( like a go webserver) are more likely to cache certain information in memory, while in PHP you're more inclined to have a linear approach to the development. As in "this is all the things i need to bootstrap, fetch and get and run before I can answer the query".
As a result the fetching of certain information wouldn't be cached by default and over time that might start adding up. The base overhead of the framework should be minimal.
You ( nextcloud ) are also subject to whoever is writing plugins. Is nextcloud slow because it is slow, or because the 20 plugins people install aren't doing any caching and a single page load is running 50 queries? This would be unrelated to NC, but I have no idea if there's any plugin validation done.
Then again, I could be talking completely out of my ass. I haven't done much with NC except install it on my RPI4 and be a bit discontent with its performance. At the same time the browser experience on the RPI was also a bit disappointing so I never went in depth as to why it wasn't performing very well. I assumed it was too heavy for the PI. This was 4 years ago mind you.
My main experience with frameworks like Laravel and symfony is that they're pretty low overhead. But the overhead is there ( even if it is only 40ms ).
The main framework overhead would be negligible, but if you're dynamically building the menu on every request using db queries it'll quickly not become negligible
And what I forgot to mention, there's the fact that it's not async. So it adds up even more to the delay when fetching stuff.
There are libraries which allow you to do stuff async in PHP ( https://github.com/amphp/amp ). It's not all async by default like Javascript. A lot of common corporate languages right now are synchronous rather than asynchronous like python, java, c#, ... By default, but allow you to run asynchronous code.
It all has their place. I'm not saying making it async won't improve some of the issues. Running a program that does 15 async processes might cause some issues on smaller systems like RPIs that don't have a lot or compute capacity like a laptop/desktop with 20 cores.
Having said that. I can't back that up at all :D.
Thanks for your insights though. I appreciate the civil discussion :)
but also, most of these languages run a compiled executable, while PHP has to go through a parser. java is another exception with it's vm, but you get my point.
so, all in all... PHP has overhead, in many ways .. sure it might be negligible (gosh, I always have to look up the spelling of this word) in some situation, but in other it adds up so much that it makes it unsuitable for the task.
yeah, I like these type of convos where there's no right or wrong... just "yes, but..."s
I mean. There's plenty of languages that have this overhead.
A base Laravel or symfony installation shows a landing page in 30-50ms (probably).
I've written ( in a lightweight framework rather that no longer exists ) a program to encrypt/decrypt strings using XML messages over http requests.
The whole call took 40-60ms. About 40-50% of that was the serializer that needed to be loaded. The thing was processing a few hundred request per minute in peak. Which is a lot more than the average nextcloud installation. The server wasn't really budging ( and wasn't exactly a beast either ).
I'm definitely not refuting that the JIT compiler adds overhead. But as in my example above, it's also not like it's adding 100ms or more per request.
If you have a very high performance app to the point where you're thinking about different transport than HTTP because of throughput you're likely better off using something else.
Circling back to the original argument my feeling remains that the same codebase in GO or RUST wouldn't necessarily perform a lot better if you just calculate in php speed and the overhead of the JIT compiler.
If you'd optimize it in rust/go. It likely will be faster. But I feel like the codebase could use some love/refactoring. But doing that is more difficult when you already have:
You don't want to piss off your entire userbase. Now I feel like I'd like to try it myself and look at the source though :'). ( I'm not saying I can do better though. It's been a couple of years).
ok... valid point, and I also agree on the refactoring argument.
To mitigate the compatibility issue, they could release a new major version, and let plugin developers simultaneously (or not) rewrite their codebase to make it compatible. That's how WordPress plugins work, although WP is a whole other mess, and not the best of examples, but they also have a large userbase and plugins.
lol, I too was thinking about trying to kickstart a similar project in Go. I'm by no means a professional go-dev (former PHP-dev, currently Node), but I think it shouldn't be that hard.
