SBE VS Vegeta

I was about to suggest Chronicle, but it looks like they have gone closed-source. The older version is still interesting to look through though. Aeron / Disruptor / SBE are good projects for inspiration as well.

Could you evaluate how it compares with SBE?

The Simple Binary Encoding (SBE) project now includes support for generating Rust code. Generated code produced does not use unsafe and has no dependencies on any other crates.

SBE

Consider a valid protobuf message with such a field. If you can locate the field value bytes, you can write a new value to the same location without breaking the message. It's obviously possible to the same with the varint type too, as long as you don't change the number of bytes - not so practical, but useful for enum field which has a limited set of useful values (usually less than 128).

Pregenerating protobuf messages you want to send and then modifying the bytes in-place before sending is going to give you a nice performance boost over "normal" protobuf serialization. It can be useful if you need to be protobuf compatible, but it's obviously better to use something like SBE - https://github.com/real-logic/simple-binary-encoding

Vegeta worth a look if you want something a bit more sophisticated: https://github.com/tsenart/vegeta

There are tons of tools to do this, I'll use Vegeta

To install vegeta, grab the right download url from https://github.com/tsenart/vegeta/releases/tag/v12.11.1 and download using the below command.

One of the easiest ways to send lots of fabricated requests at the same time is to use the Vegeta load testing tool. Being a load testing tool, it can send lots of requests consistently, every second, to the given target URL. You can read more about Vegeta on GitHub. The binary can be downloaded and used without installation.

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 Java socket closed errors - K6 https://k6.io/ but I can't bring down my infra with - wrk https://github.com/wg/wrk no matter what parameter I put it doesn't make enough requests per second, I put the same parameters as on a tutorial and I don't get the same result...

I use tools like vegeta and wrk2 to answer those questions.

A module can be an executable and a library at the same time. For example, https://github.com/tsenart/vegeta

Some tools to investigate: * https://prometheus.io/ * https://github.com/tsenart/vegeta

No, not at all. You just need a tool like Vegeta.
