-NOTE TO PEOPLE WHO THINK THAT FreeBSD 11.x IS SLOW:
- FreeBSD 11.x has many debugging features turned on, in both the kernel
- and userland. These features attempt to detect incorrect use of
- system primitives, and encourage loud failure through extra sanity
- checking and fail stop semantics. They also substantially impact
- system performance. If you want to do performance measurement,
- benchmarking, and optimization, you'll want to turn them off. This
- includes various WITNESS- related kernel options, INVARIANTS, malloc
- debugging flags in userland, and various verbose features in the
- kernel. Many developers choose to disable these features on build
- machines to maximize performance. (To completely disable malloc
- debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely
- disable the most expensive debugging functionality run
- "ln -s 'abort:false,junk:false' /etc/malloc.conf".)
