## Benchmarks
Microfetch's performance is capped by hardware-specific race conditions, meaning
it may (at times) depend on your hardware. However, the overall trend seems to
be < 2ms on any modern (2015 and after) CPU. Below are the benchmarks with
Hyperfine on my desktop system.
The performance may be sometimes influenced by hardware-specific race
conditions, or even your kernel configuration meaning it may (at times) depend
on your hardware. However, the overall trend appears to be less than 1.3ms on
any modern (2015 and after) CPU that I own. Below are the benchmarks with
Hyperfine on my desktop system. Please note that those benchmarks will not be
always kept up to date, but I will try to update the numbers as I make
Microfetch faster.

As far as I'm concerned, Microfetch is significantly faster than every other
fetch tool that I have tried. The only downsides of using Rust for the project
(in exchange for speed and maintainability) is the slightly "bloated" dependency
trees, and the increased build times. The latter is very easily mitigated with
Nix's binary cache. Since Microfetch is already in Nixpkgs, you are recommended
to use it to utilize the binary cache properly

Microfetch is packaged in [nixpkgs](https://github.com/nixos/nixpkgs). You can
get it through the unstable channel for the time being. The Nix flake can also
be used for bleeding-edge builds.
Microfetch is packaged in [nixpkgs](https://github.com/nixos/nixpkgs). It can be
installed by adding `pkgs.microfetch` to your `environment.systemPackages`.
Additionally, you can try out Microfetch in a Nix shell.
```bash
nix shell nixpkgs#microfetch
```
Or run it directly with `nix run`
```bash
nix run nixpkgs#microfetch
```
Non-Nix users will have to build Microfetch with `cargo`. It is not published
anywhere but I imagine you can use `cargo install --git` to install it from
