Shared dynamic libraries do reduce the “wear and tear” on an SSD. The binaries are loaded a single time and shared across processes - slightly longer startup times for the dynamic linkage.
It is highly beneficial with large runtimes vs small standard library usage in tiny utilities. > On Jan 28, 2023, at 10:46 PM, Kurtis Rader <kra...@skepticism.us> wrote: > > > It does not surprise me that your shared run-time build takes more time than > the usual static build.
