# ⚡blazingly fast⚡

|
|
I conducted a series of quick tests, using wrk with simple HTTP servers written
|
|
in GO and in zig zap. I made sure that all servers only output 17 bytes of HTTP
|
|
body.
|
|
|
|
Just to get some sort of indication, I also included measurements for python
|
|
since I used to write my REST APIs in python before creating zig zap.
|
|
|
|
You can check out the scripts I used for the tests in [./wrk](wrk/).
|
|
|
|
## results
|
|
|
|
You can see the verbatim output of `wrk`, and some infos about the test machine
|
|
below the code snippets.
|
|
|
|
**Update**: I was intrigued comparing to a basic rust HTTP server.
|
|
Unfortunately, knowing nothing at all about rust, I couldn't find one and hence
|
|
tried to go for the one in [The Rust Programming
|
|
Language](https://doc.rust-lang.org/book/ch20-00-final-project-a-web-server.html).
|
|
Wanting it to be of a somewhat fair comparison, I opted for the multi-threaded
|
|
example. It didn't work out-of-the-box, but I got it to work and changed it to
|
|
not read files but outputting a static text just like in the other examples.
|
|
**maybe someone with rust experience** can have a look at my
|
|
[wrk/rust/hello](wrk/rust/hello) code and tell me why it's surprisingly slow, as
|
|
I expected it to be faster than the basic GO example. I'll enable the
|
|
GitHub discussions for this matter. My suspicion is bad performance of the
|
|
mutexes.
