About

Libuv is a super popular cross platform Networking Event Loop Engine writtent in C , it's a main Networking engine for Node.js. MIO is a cross platform Networking Event Loop Engine written in Rust with 0 cost of abstraction principle.

So because of the "war" between Rust and C/C++ in terms of performance and stability, and because of I have an application which is currently using Libuv, wanted to benchmark MIO and Libuv as a different language implementations of almost the same OS API's. Both benchmark projects built for super easy usage, so you can run benchmarks on your machine. It's tested for MAC and Linux.

Usage

For making some benchmarking we need 3rd tool for just sending and reading network traffic, it's built with Go. So the basic usage is following

Running MIO Tcp Echo server - you will need Rust and Cargo installed

# this will start TCP echo server on port 8888
cd tcp_mio/ && cargo run --release

Running Libuv Tcp Echo server

# building C code
cd tcp_uv && ./build.sh

# Starting Libuv TCP echo server on port 8888
./tcp_uv/build/tcp_uv 8888

Starting Benchmarking tool

# this will open 100 concurrent connections to 8888 port on localhost
# and will start sending "LICENSE" file content
# you can choose any file for benchmarking
go run bc.go localhost:8888 100 LICENSE

NOTE: Make sure that file is not large, because you may crash your OS. During TCP Write process bytes would stay in memory until write is done.

Results

I'll add some results for multiple OS's and instances
