I was building a very performance sensitive API service using Rust and I was trying to find out which http framework I should use
as there a lot of frameworks out there for Rust. So, I just shortlisted some of them and I ran a hello world route
for every frameworks
and its result is very interesting.
I used wrk
to test those http servers:
$ wrk --latency -t4 -c200 -d8s http://127.0.0.1:8081
I ran all those tests on:
Intel Core i7 CPU @ 3.20GHz × 12, 16GB of RAM
Before run, I created a release build:
$ cargo build --release

In order to run a fair comparison a suitable environment variable should be set
while running, ROCKET_ENV=prod ./rocket
.
Indeed, by default is set to dev
, and it is spending a lot of time logging
everything on the console.
hyper
-> Perfect for an app which requires more controls on http and
performance. It provides async
with tokio.rs
.
gotham
-> A high-level version of hyper
.
actix-web
-> Provides a very high-level API and injects some boilerplate code
as well as runtime. It provides async
with tokio.rs
.
warp
-> A very high level version of hyper
and easy to use and it requires
a few lines of codes to start a server. It provides async
with tokio.rs
.
rocket
-> High level, actively developed and quite used. Nevertheless it has
not the same performances as the others.
