            Node.JS Load Testing tools with thousand of virtual users
            Asked 2021-Mar-03 at 15:00

            The goal is to make a load test of the Node.JS server on AWS.

            The server should support extremely high peaks of different users per second (20K) event more. I tried a few load test tools like Artillery and LoadTest. Unfortunately didn't manage to get more than 3K VUs by setting up the Kuberense cluster of 16 cores with 64G in total. The result was less than 60 VUs per pod within 100% CPU utilization. When I tried to get at least 200 VUs on 50 pods

            Probably anyone an idea of less CPU-consuming load testing tools.

            ANSWER

            Answered 2021-Mar-03 at 15:00

            If you have only one physical (or virtual) server which doesn't scale it doesn't make a lot of sense to use container orchestration tools like k8s as it doesn't add any value and just consumes resources.

            With regards to resource consumption by the load testing tool, there is a bare minimum which will always be required like:

            • operating system thread footprint in memory
            • request and response size
            • extra resources required by the language runtime

            From my previous experience Tsung provides the maximum throughput on minimal resources.

            However depending on the nature of your test you might want to consider other tools, i.e. see Open Source Load Testing Tools: Which One Should You Use? article for more options.

            Narrow down the tools selection to the ones which support network protocols required for your application load testing and don't forget that the majority of tools assume performance tuning.

            Also don't forget that the real users don't hammer the application non-stop, they need some time to "think" between operations so first of all ensure that your virtual user behaves like a real user, it might be the case you just to need to make the workload more realistic and the current hardware/software setup will be sufficient

            Reducing Node + Express + Socket.io memory usage when using mongoose
            Asked 2021-Mar-03 at 13:02

            I'm using Node + Express (running locally) and connecting to a MongoDB hosted on MongoDB Atlas. My project is a behemoth that started a while back using MDN's Local Library tutorial, and it grew as I learned how to use Express, sockets, mongo, etc. So some code in it is very bad, some is less so. Now, with a mostly feature-ready product, it's having high memory usage when multiple people connect.

            Using Artillery, I have 5 users/second hit my /join_session endpoint for 20 seconds. This spikes memory usage from ~35MB to ~450MB. Full disclosure, I'm terrible at reading Chrome's Node.js Devtools for memory usage. But here's what I see under system/Context:

            Object Origin Distance Shallow Size Retained Size this::ConnectionPool @2726315 connection_pool.js:147 17 184 0% 351324152 79% ::Denque @3436241 index.js:6 18 56 0% 351320592 79% _list::Array @3436499 19 32 0% 351320536 79%

            That array has 1024 elements. Here's the statistics tab from Chrome's inspector

            So it seems like mongoose's connection pool is the problem. I haven't changed my pool size, so that's the default of 5. I set up my connection in an external file that I require in App.js.

            App.js

            require("./mongo.js");

            mongo.js

            ANSWER

            Answered 2021-Mar-03 at 13:02

            So, as it turns out, the memory usage on the above test isn't that far off of normal. It's about 6MB per client, which isn't the worst, I just need a better server if I expect ~200 concurrent clients, and in particular I need more than the free tier of mongo cloud to serve DB requests more quickly. In production, the real memory spike I was seeing had NOTHING to do with the above. Instead, it was because I was repeatedly fetching an entire collection with ~10k records, each of which was a JSON object with props. Parsing that takes lots of memory, really fast, and will need to be the subject of a different post!

            How can artillery.io load testing be distributed across multiple cores
            Asked 2020-Sep-15 at 02:09

            It is likely realized when attempting to run larger scale tests with artillery.io that high CPU warnings will be displayed. As this technology runs a node process to drive test scenarios defined in yaml scripts, the single-core process can attempt to push so much throughput before lacking in CPU resources. A quick Google search will bring about the following result describing some features within artillery to distribute artillery scenarios across multiple cores, https://artillery.io/blog/artillery-20-preview-multicore, but unfortunately does not seem to be the case...

            If your build takes longer than 10m without output this will happen.

            You can use travis_wait to print something to the console each minute, as per the docs: https://docs.travis-ci.com/user/common-build-problems/#build-times-out-because-no-output-was-received

            Just travis_wait {your_command} and you should be good to go.

            Be aware that your build taking longer than 10m could be a indicator of a more complicated underlying problem/freeze.
