So while compiling each file separately in parallel is
potentially much much faster, the produced release binary may
be slower due to less/no cross-module inlining (e.g., LDC's
option is still experimental and known to have issues).
In fact single-module compilation is slower than package
compilation most of the time due to the redundant
parsing&semantic of common imports. As an extreme example, last
time I tried, single-module compilation for gtkd was ~10x
slower than compiling the library at once. Savings on
recompilation hardly make up for this huge overhead.
Overall I'd recommend organizing and building subpackages when
a project becomes too big.
Per package is significantly faster.
As far as I know the only build system that does this by default
for D is reggae.
