(For newcomers:) more tests and benchmarks

[Berrysoft]

We need more tests and benchmarks. They will help us debug and improve the code quality.

This issue is for newcomers of this project. If you would like to contribute, but don't know which work you can do, you can start with a test or a benchmark. The experience with compio will help you get familiar with the code.

See monoio and tokio-uring for reference of tests.

I added compio as part of ntex benchmarks to tech empower

test run example is here

I have a question, I am currently trying to decided between monoio and compio. The challange I face with monoio is largely related to some hard cross compilation issue.

I sincerely appreciate these initial benchmarks. However, are there any benches related to scaling per additional core?
For example, monoio has some nice benchmarks on its Readme with 1, 4, and 16 cores that clearly showcase the near linear scalability while preserving low latency.

I am asking because I am experimenting with some kind of MPP architecture for message streaming and in that case, latency, and scaling matters quite a bit.

AFAIK monoio doesn't support Windows. Cross-platform is a key feature of compio.

However, are there any benches related to scaling per additional core?

Not now. I have noticed the nice benchmarks in monoio, but I didn't have time to write a similar one. That's what this issue is for: calling newcomers to contribute compio starting from adding more tests and benchmarks. PRs are welcome.

@Berrysoft Thank you,

I have drafted an initial benchmark based on the monoio bench to compare Tokio, monoio, and compio.

it is a simple ping-pong task where the client calculates how many responses it got from the server.

However, as I am new to compio I don't know if that is the best way to implement the task.

Would you please take a look and give some feedback to make the implementation better?

Two comments:

1. You don't need to implement the client yourself (L31 -- L41). The repo has already got a testing client.
2. Use read_exact and write_all just like the monoio server.

The dispatcher is a suitable way here to write a thread-per-core server. However, I'm not sure which one should be better, either a single-threaded server, or a thread-per-core server. You can write both with compio and benchmark them.

Hello, I’d like to adapt a Hyper-based HTTP Client library for use with compio. This will involve porting much of Hyper’s underlying code, and making special adjustments for compio where necessary. Do you think it can work similarly to how it does with Tokio? I’m new to compio and not very familiar with its development progress yet.

@0x676e67 You can checkout compio-rs/cyper and see if that fits your need

Nice, the compio-rs/cyper project showed me that this is possible.

Hi, I didn't find the git repository behind compio buffers. Are these documentations generated from the rust code?

The website source is in another repo: https://github.com/compio-rs/compio-website

Will compio-website serves as the doc site of compio instead of its crates on docs.rs for the users?
