What I meant was that without -O it's about 2.2, with -O it's 9 ish and then increasing optimisation to -O2 and -O3 makes some but not a vast improvement. There may be other flags I should be using, of course. > On 15 Apr 2025, at 15:36, Yuri Davidovsky (as work at disclosure dot ie) <[email protected]> wrote: > > > >> On 15 Apr 2025, at 15:22, Tim Bradshaw <[email protected]> wrote: >> >> With no optimisation flags C is doing about 2.2GFLOPS.

Or do you mean, its performance is reduced by 2.2 gflops when not using -O3? _______________________________________________ Lisp Hug - the mailing list for LispWorks users [email protected] http://www.lispworks.com/support/lisp-hug.html
