ffi-overhead
============
comparing the c ffi overhead on various programming languages
Requirements:
- gcc
- tup
- zig
- nim
- v
- java7
- java8
- go
- rust
- d (dmd and ldc2)
- haskell (ghc)
- ocaml
- csharp (mono)
- luajit
- julia
- node
- dart
- wren
- elixir
My environment:
```
- Intel i7-3630QM laptop (4cores, HT) with 16g ram
- Ubuntu 14.04 x64
- gcc/g++ 5.4.1
- tup 0.7.4
- zig 0.2.0
- nim 0.14.3
- v 0.2.2 aebb551
- java 1.7.0_72 and 1.8.0_91
- go 1.8.0
- rust 1.17.0-nightly (c0b7112ba 2017-03-02)
- dmd 2.0.71.1
- ldc2 1.9.0
- ghc 7.10.3 (at /opt/ghc)
- ocaml 4.06.1
- mono 5.12.0.226
# dynamic languages
- luajit 2.0.4
- julia 0.6.3
- node 6.9.0 (at /opt/node)
- dart 1.22.0 (at /usr/lib/dart)
- wren 0.1.0
- elixir 1.6.5 (Erlang/OTP 20)
```
### Initialize
```sh
tup init
```
### Compile
```sh
./compile-all.sh
```
Compile opts:
- -O2 (gcc - applies to c/jni/nim)
- -C opt-level=2 (rust)
### Run
```sh
./run-all.sh 1000000
```
Measurement:
- call the c function "plusone" x number of times and print out the elapsed time in millis.
```c
int x = 0;
while (x < count) x = plusone(x);
```
- 2 samples/runs
## Results (500M calls)
```
./run-all.sh 500000000
The results are elapsed time in milliseconds
