Ensure that optimization is turned on when building Satsuma.
- As graph algorithms are computationally intensive, Satsuma is very sensitive to optimization.
Run your program from outside the IDE, by launching the .exe file directly.
- JIT optimization is disabled by default when running from within the IDE.
Target 64-bit instead of 32-bit.
- Set your project platform as either Any CPU (recommended) or x64 (not recommended). Uncheck Prefer 32-bit if using Any CPU.
  - This does not apply for projects which need to call 32-bit unmanaged DLL's!
