• AWS SnapStart - Part 19 Measuring cold starts and deployment time with Java 17 using different Lambda memory settings

  The results of the experiment below were based on reproducing approximately 100 cold starts for the duration of our experiment which ran for approximately 1 hour. For it (and all experiments from my previous articles) I used the load test tool hey, but you can use whatever tool you want, like Serverless-artillery or Postman. - Source: dev.to / 4 days ago

• AWS SnapStart - Part 13 Measuring warm starts with Java 21 using different Lambda memory settings

  In our experiment we'll re-use the application introduced in part 9 for this. There are basically 2 Lambda functions which both respond to the API Gateway requests and retrieve product by id received from the API Gateway from DynamoDB. One Lambda function GetProductByIdWithPureJava21Lambda can be used with and without SnapStart and the second one GetProductByIdWithPureJava21LambdaAndPriming uses SnapStart and... - Source: dev.to / 4 months ago

• Amazon DevOps Guru for the Serverless applications - Part 2 Setting up the Sample Application for the Anomaly Detection

  For running our experiments to provoke anomalies we'll use the stress test tool. You can use the tool of your choice (like Gatling, JMeter, Fiddler or Artillery), I personally prefer to use the tool hey as it is easy to use and similar to curl. On Linux this tool can be installed by executing. - Source: dev.to / 7 months ago

• The TCP receiver only ack the minimum bytes of MSS one by one

  The client and server nodes are CentOS7.9/X86_64. If the HTTP POST requests were sent directly to the server with hey -c 1, there are about 0.2% of cases that may timeout. If the HTTP POST requests were sent through an NGINX proxy on the client node, there are about 20% of cases will timeout. I've confirmed that only one backend node has this problem. All other nodes are 100% succeeded even with higher throughput. Source: 11 months ago

• Benchmarking SQLite Performance in Go. Using Go's awesome built-in simple benchmarking tools to investigate SQLite database performance in a couple of different benchmarks, plus a comparison to Postgres.

  64 concurrent requests isn't a lot. Modern web apps can typically handle much more than that (depending on what the request does, of course). Try it yourself with a load tester like https://github.com/rakyll/hey against a Go HTTP server, for example the one I've built in https://www.golang.dk/articles/go-and-sqlite-in-the-cloud.

• GraphQL Fastify vs Apollo Server — Learnings from the real world

  To compare the two servers, we used two packages. The first one was ClinicJS, an open-source set of tools used to diagnose NodeJS performance issues, which also gives you suggestions and points you in a direction to fix the diagnosed problems. The second one was hey, a CLI tool to send some load to the server. Below we show how we use them and the results of these comparisons. - Source: dev.to / over 1 year ago

  Using cluster and worker threads. The code is here, but completely undocumented, as I’ve been side tracked by a few other things[0]. I’m currently looking into porting that project to Bun, so it’s possibly dead in its current form. I was planning on turning that into a library, but Bun nerd sniped me. You need the “hey” tool to run the benchmarks[1] the way that I was running them. [0]... - Source: Hacker News / over 1 year ago

• CloudFront Functions: 20% faster than CloudFlare Workers, 230% faster than Lambda@Edge

  I decided to keep my performance tests simple, using curl to make requests to each of the 3 services hosting my function code to forward a short link request to the full URL (e.g., example.com/git forwarding to a specific GitHub repo). While I could have turned to tools like Apache Bench, Hey, Artillery, or Iter8 for more options and testing features, I wanted to use the most direct request method which would also... - Source: dev.to / about 2 years ago

• Ask HN: JMeter Alternative?

  I've used LoadForge before for stress testing: https://loadforge.com I found it a good middle-ground between DIY tools like "hey" and the likes of JMeter and K6. LoadForge is really just a frontend for Locust [2]behind the scenes so all tests are written in Python which might not fit your requirement for Go/Rust, but it's affordable and quick to get started with.
