OK, ran it now and I got: <<< shlomi[fcs]:$trunk/fc-solve/source$ perl scripts/time-fcs.pl llvm*DUMPS/* llvm-2-DUMPS/dump002:95.6706857681274 llvm-3-DUMPS/dump002:95.6713609695435 llvm-DUMPS/dump002:96.0500059127808 shlomi[fcs]:$trunk/fc-solve/source$ >>> So the lowest run when running it in a virtual console without X running, and while renicing it to the highest priority, makes it run at 95.67 seconds, vs. gcc's 85.13 seconds.
