To gather result, build `hackbench': # eval $(sed '/#gcc/!d; s/.//' hackbench.c) then, reboot in single mode, mount / read-write, adjust whatever you have to adjust and run the script: # sh hackbench.sh [light|medium|heavy] $(pwd)/hackbench this will run a complete iterations over all the possible tunables and gives you a `results.yml' that you can feed to the previous script. - Arnaud > Thanks, > Florian _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
