What hardware configuration? What BIOS setting? What loader.conf/sysctl.conf setting? What `vmstat -i`? What `top -PHS`? what ==== pmcstat -S CPU_CLK_UNHALTED_CORE -l 10 -O sample.out pmcstat -R sample.out -G out.txt pmcstat -c 0 -S CPU_CLK_UNHALTED_CORE -l 10 -O sample0.out pmcstat -R sample0.out -G out0.txt ==== _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
