• Where misunderstood with Monoliths and Kubernetes: Benchmark

  Too many teams migrate to Kubernetes based on vendor benchmarks or blog posts that test trivial workloads: a "hello world" endpoint with no business logic, no GC pressure, and no network overhead. Our benchmark proves that synthetic workloads lie: the 12% latency gap between monolith and K8s at 1000 RPM disappears entirely if you test a "hello world" endpoint (K8s overhead is 2ms, same as monolith). For real... - Source: dev.to / 3 months ago

• Cache Comparison: Redis 8.0 vs. Memcached 1.6 vs. Varnish 7.4 for Web App Performance

  Implemented cache warming for top 10k product pages via a nightly cron job using wrk to pre-populate Varnish and Memcached. - Source: dev.to / 3 months ago

• uRocket - Reactor Networking in C# with io_uring

  Since I do not own multiple server machines or top of the like Network Interface Cards, there is of course some level of noise in these benchmarks. The load is generated using wrk and the source code for each: uRocket System.Net.Socket. - Source: dev.to / 7 months ago

• Bombardier: Fast cross-platform HTTP benchmarking tool written in Go

  Cool, I didn't see this tool before. I have tried most open source load testing tools out there, as part of writing a couple of review articles on them (https://grafana.com/blog/2020/03/03/open-source-load-testing-tool-review/) and my gut reaction is this one looks like a Golang alternative to Wrk (https://github.com/wg/wrk) in that its main feature is speed. I'd bet Wrk... - Source: Hacker News / almost 2 years ago

• Running a Billion Workflows a month with Netflix Conductor

  We used wrk2, a fantastic tool to generate stable load on the server. Wrk2 improves on wrk and adds the ability to generate sustained load at a specific rate (-R parameter). - Source: dev.to / about 3 years ago

• So how does WSGI concurrency work?

  I am using a tool called wrk to make a bunch of requests to my website, and changing the concurrency of the requests drastically changes the result, with concurrency set to 1, I get 894 requests made in 10 seconds, and when I set concurrency to 10, I get 8549 requests. This linear scaling stops when increasing the concurrency more drastically (18805 requests for 100 and 19814 for 500 concurrency). Source: about 3 years ago

• What tools you use for http load testing?

  Good morning What tool do you use to test your infra in terms of http load ? A tool that works, I tested : - https://github.com/tsenart/vegeta but it returns 0 errors or a http_net error from Golang - LOIC (Low Orbit Ion Canon) https://github.com/NewEraCracker/LOIC but the requests do not appear in my nginx logs and I feel no slowdown - Apache Jmeter https://jmeter.apache.org/ but I can't drop my infra and I have...

• My Rust server on a $20 VPS handles 10k requests per second with no caching. Is it just me or is that crazy ?

  You could try to just blast it with wrk or bombardier. Can easily get around 50k requests on consumer machine. Source: over 3 years ago

• Node.js Cluster vs Axum, a.k.a. yet another benchmark :)

  The benchmark is a simple "hello world" server that returns a JSON response. Server frameworks are correspondingly Fastify for Node and Axum for Rust. Both were running on my laptop (specs should not matter, IMHO, as this is not about absolute numbers). Test load was provided by wrk that was running on the same machine. Source: almost 4 years ago
