## Networking experiments with OCaml 5's effects
Goal: port Mirage's TCP/IP stack on top of OCaml 5's effects for
more manageable async code.
### Creating a 4.12.0+domains switch
```
opam switch create 4.12.0+domains --repositories=multicore=git+https://github.com/ocaml-multicore/multicore-opam.git,default
```
### Creating a 5.0.0+trunk switch
```
opam switch create 5.0.0+trunk --repositories=alpha=git+https://github.com/kit-ty-kate/opam-alpha-repository.git,default
```
Optional: install lsp server:
```
opam pin -y git+https://github.com/patricoferris/ocaml-lsp#dc9a4ef8529628fe023e1ed034ffe6b517ea4f1a
```
### Installing the project
```
git clone --recursive https://github.com/TheLortex/networking-experiments
cd networking-experiments
opam install --deps-only ./ -t
dune runtest
```
## HTTP SERVER
Requirements:
- a tap0 interface configured with 10.0.0.1/24 as an address
Bench:
- `dune exec test/http_tcpip.exe`
- `wrk -t16 -c256 -d5s http://10.0.0.11:8080/`
Results (lots of variation):
```
