Comparing C# and V Boids Algorithm Implementations

Running the C# program:

dotnet run

Creating a release version of the C# program:

dotnet publish -c Release -r ubuntu.20.04-x64

The generated executable will be in /v/vnew/bench/vectors/bin/Release/net7.0/ubuntu.20.04-x64/publish/vectors Its size is ~64MB . After stripping, the executable shrinks to just 11MB, but unfortunately it also stops running after stripping :-| .

Compiling and running the V program:

v crun vectors.v

... produces and runs a vectors executable which is ~1.3MB in size.

Compiling and running the V program, compiled with -prod:

v -prod crun vectors.v

... produces and runs a vectors executable which is ~176KB in size. After stripping, the executable shrinks to 157KB. It can still run after stripping.

Note: using crun will make sure that the compilation will happen just once at the start, and then the executable will be just reused by the subsequent commands with identical options. It will also ensure that the compiled executable will not be removed, unlike run .
