I'm using AWS EKS with kube-prometheus-operator and wanna see nginx metrics on different path of my app like /api/some_method

[@ZergStylexDD]

I spent some time on Google, and as I understood it, this is only achievable if we specify many different paths in the Ingress K8S resource. In this case, we will see these paths in our metric. But we always need to update this configuration whenever we add a new endpoint to our application...

[@FrankTaylorLieder]

Thanks for making this video. I too was surprised by the results: why do they show Rust so much slower (latency) and why does it consume more CPU and fluctuating level of CPU (there is no GC to add periodic overhead)? I took the code and ran test 1 (static get devices) locally (M1 Mac Studio) to see if I could repro your results. I found something different. Both Go and Rust performed incredibly similarly: about 570us per request... But I was driving it with 50 concurrent threads achieving about 27k requests per second. I get similar results at 100 concurrent threads (50k requests/s). Further, with these tests I see Rust taking 55% CPU / 9MB RAM consistently, whilst Go is fluctuating 130-180% CPU / 20 MB RAM during the run. My results are not directly comparable with yours (not network between the client and server, different machine, etc)... but the relative performance is comparable. I see latency parity between the two languages. This is what I would expect for such a simple test... returning static data, both compiled and optimised languages. As expected I see Go using more memory and a little more CPU to cover off its overheads like GC. Can you double check your Prometheus graphs to make sure the CPU usage graphs are the right way around? I can't come up with a suggestion for the differing latency figures... Any ideas Anton?

[@AntonPutra]

thank you for taking the time! The issues was a client running in the Kubernetes pod (job), i have improved test design and now can achieve ~20k RPS in Kubernetes with 2cpu and 256mi memory. it does not mean previous tests were incorrect it just client wasn't able to generate more load Also, someone raised a PR to improve Rust code, so I will retest and if it makes a difference release a result - github.com/antonputra/tutorials/tree/main/lessons/203/rust-app-v2

[@FrankTaylorLieder]

​@@AntonPutra Thanks for replying. I look forward to seeing the updated results. Coming back to the CPU graph. I saw from your video today that all three Go frameworks generated load fluctuations. Your graphs for test1 in this video show Go with almost completely level/smooth CPU and Rust with quite variable CPU usage. Can you confirm that the graph key is the right way around... That said, I am super impressed with the performance of Go in these tests.

[@AntonPutra]

​@@FrankTaylorLieder I'll double-check. This time, I generated the load from 20 different pods in K8s instead of just one. Also, I added random sleep in the Go client, which could potentially cause spikes. When I reduced the random sleep time interval from 1000ms to 40ms, the graph looked much smoother.

[@konoko-o3o]

It's very interesting to see comparisons like this, especially with Actix and Fiber, which are among the fastest tools for backend development in Rust and Go, respectively. The specific requirements of each project can heavily influence the choice of tool. While Fiber boasts lower latency per request and less CPU usage, it does consume more memory. On the other hand, Actix might have higher latency and use more CPU, but it's significantly more memory-efficient. Considering that memory is more expensive than CPU usage in cloud services, this trade-off becomes even more crucial if you are deploying the service on-premises or in the cloud. Additionally, Go's ease of use makes it simpler to onboard new developers, even those without prior experience, whereas Rust might have a steeper learning curve. It's always a good practice to encourage developers to conserve memory allocation when working with Go, given its tendency towards higher memory consumption. These subtle observations can significantly influence the choice of tool depending on the project's specific requirements.

Having seen these results - I think I might put in some pull requests for Linux drivers written on Golang! (topical Geek joke). It was fascinating to see two compiled languages going head to head. I was surprised to see them being so neck and neck, Memory usage was the principal difference, and on that I have some comments (in no way a criticism of the video which was illuminating and objective, in running the two languages against one another in default configuration - like most people use them). Memory usage is not really an efficiency metric, because a garbage collecting language will only carry out a full garbage collect when necessary. Necessary being hitting the defined threshold. Typically this would be configured to 80% of available memory - you can see this when when the load increases and there is an initial spike. Resource pools and statically sized queues are also a reason that memory usage of an application can appear initially appear high, but then not get any higher. As an embedded software engineer, the approach was that memory is not there to be squandered but it is there to be used and abused, to keep down latency. Caching previously loaded and potentially still useful disk pages in RAM is another example of this. This is something the OS will do for the app if you let it - but that usage has to be accounted for against one process or another. So, the takeaway is - memory can be traded for latency - and you can code or configure an app to play to either of these as priority dictates. If you know the load in advance you can vary the budgets considerably. Caveats : I have had to say "the compression algorithm will take up more room than the data" and databases often default to linear searches because using an index is slower than just going through the data (the point being that you shouldn't assume complex algorithms make things quicker). IOPS on the database store can be an almost invisible bottleneck. I'd like to see a Node.JS app added to the mix. The compiled languages people expect it to be rubbish, but I suspect it would run Rust and Golang close on this app (if you are going to allow "go routines" you would have to allow multiple Node instances listening on the same port).

[@AntonPutra]

[@mariogutierrez4989]

The scales are a bit deceiving. They look more drastic than they really are. Considering how much less time it takes to write a program a Go language with concurrency, I would choose Go.

Not an expert but I think the Rust code can be slightly optimized: get_devices seems to allocate the vector every time it runs, which can be time consuming, and also you might squeeze a bit more performance with parking_lot and RwLock instead of Mutex.

get_devices from main has the potential to be wildly inefficient. It's not even so much about the vector not being const (uuid! is validated at compile time). The problem may be in the mac and firmware fields of the Device struct. With the current implementation it's a whole wonder why Device has owned data as opposed to string slices. What you end up doing is paying the price for a heap allocation (as stated in the docs for From for String) which you don't need since this data can be a &'static str. On top of that one doesn't need UTF-8 strings to represent MAC addresses and firmware versions. Using an ascii string is something that both solutions would benefit from. Hopefully rustc is smart enough to figure all of these things out and not include all of the above mentioned overhead, I haven't analyzed the function that closely.

Thank you for the feedback, actually one of the PRs that i received is to change uuid to string - github.com/antonputra/tutorials/pull/252 as well as another one to improve performance - github.com/antonputra/tutorials/pull/253 I'll retest in a couple of days along with some other tips and release results

Can u test go/rust vs userver (c++)

[@AntonPutra]

yes soon!

[@aliimranalfred]

I strongly suggest to reupload this very same test by adding below lines in rust-app's `Cargo.toml` file ``` [profile.release] lto = true strip = true opt-level = 'z' panic = 'abort' codegen-units = 1 ``` I am very curious to see the after results...

[@AntonPutra]

thank you! I'll try it. Also someone raised a PR to improved rust code, let me know what do you think? - github.com/antonputra/tutorials/tree/main/lessons/203/rust-app-v2

i think axum is a much lighter framework and more closer to fibre

[@AntonPutra]

will test!

Would be great to try with Axum

will do little bit later

I think this shows that Discord was wrong to throw their entire codebase away for their "performance" issues with Go. There was something else going on there IMO and not just "Go slow we move to Rust haha"

I had a Golang client that generated load, and I had to use 8xlarge instances. After rewriting it in Rust, I was able to use 4xlarge instances, 50% infra savings for me for running these tests.

I would very scared just to use those instances 😅

i don't understand at 1.5k RPS if they are using only 10% Memory, 8% CPU then why they are falling?

i got a lot of tips how to improve rust code as well as few PRs, will release updated results in a couple of days. that particular issue was due to absence of timeouts on the client side

which one? I already merged 2 PRs.. I'll test soon.. PR - github.com/antonputra/tutorials/pull/253 PR - github.com/antonputra/tutorials/pull/252

use let now = Instant::now(); and now.elapsed() for rust for benches. not SystemTime. It's quite strange why it uses so much cpu at the begining. need to dig into sources

Go is amazing! But whenever you see C/C++/Zig being beaten by Go/Java/etc. you know something’s wrong…

Well, I got a lot of tips and a couple of PRs to improve my Rust code. I'll publish the results in a few days. It can beat Go's standard library, but even Rust experts weren't able to optimize the AWS SDKs to make them more efficient than Go's AWS SDK v2 🤷‍♂️

@@AntonPutra They actually did and according to their official blog Rust is faster, I can't post links because my comments get deleted, but Google search can give you top level results.

@@AntonPutra sounds great! Hmm well yes possible the AWS lib just isn’t there yet but then that’s an implementation issue on AWS side. No wonder considering how they create their sdks 😬

[@adcodes]

IMHO, Go wins. 🎖 Go uses three times more memory but four times less CPU. I think Go is the better choice, since the performance is only in memory usage which doesn't actually translate to more requests per second, and also the same app in Go has better latency (although I'm not sure if it noticeable). Thanks for the video.

Go Fiber is cheating with HTTP1.1 which is why I use it for my high volume CMS. I don't see the landscape of Web Servers changing much until HTTP3 QUIC becomes standard. Honestly any Web Service is going to be winner by simply using Go or Rust over Python or Node (compiled over interpreted).

[@AntonPutra]

thanks for the feedback! fiber seems to be very fast, i'm going to release Go (stdlib vs fiber vs gin) in a couple of days

[@ulrich-tonmoy]

So go is better choice here as writing code is easier and it takes more memory than rust but others are similar or better can you do one with erlang vm lang like elixir or gleam vs go or rust

One important thing that these benchmarks doesn't take into consideration when choosing a programming language or framework is the developer feedback loop. For instance, I know that python is probably one of the slowest (in execution time) programming languages that are used for web applications. However the developer feedback loop is such a big difference compared to the compiled languages, that I would have it as my default go to language.

[@AntonPutra]

i like python as well, you can write data pipelines with spark and ml stuff so python is not going anywhere
