These features attempt to detect joe> incorrect use of system primitives, and encourage loud failure joe> through extra sanity checking and fail stop semantics. They joe> also substantially impact system performance. If you want to joe> do performance measurement, benchmarking, and optimization, joe> you'll want to turn them off. joe> How do I turn them off? The document says: This includes 1) various WITNESS-related kernel options, 2) INVARIANTS, 3) malloc debugging flags in userland, and 4) various verbose features in the kernel. For 1), 2) You can find the comment as "Debugging for use in -current" in /usr/src/sys/i386/conf/GENERIC. For 3) see TUNING in malloc(3) For 4) You may find them in UPDATING items (newer than base system) or Other options may be found by "sysctl -a" , I think. and read COMMON ITEMS at end of UPDATING.
