Hello
How can I increase the speed of executable files created via :
`dub build -b release`
try `dub build -b release --compiler=ldc2`
Then you can set some specific DFlags for ldc, like -O3 or --mcpu
I am unable to parallellise all of it, as it depends on part of
the result being calculated before something else can be
calculated.
I have many `nonsafe, nonpure` functions.
`nothrow` presumably opens optimisation opportunities with the
stack management, although it's not verified
Classes are virtual by defalut.
set them final when possible. When not possible set the virtual
methods that
are not overridden `final`.
Profiling doesn't help, because different input is causing
different parts of the program to become slow.
if you're on linux, you can try callgrind + kcachegrind instead
of builtin intrumentation.
Thank you.
