-The kernel memory allocator,
-.Xr malloc 9 ,
-will keep statistics on its performance if this option is enabled.
-Unfortunately, this option therefore essentially disables the
-.Fn MALLOC
-and
-.Fn FREE
-forms of the memory allocator, which are used to enhance the performance
-of certain critical sections of code in the kernel.
-This option therefore can lead to a significant decrease in the

-Examples of such code include the
-.Fn namei
-routine, the
-.Xr ccd 4
-driver,
-and much of the networking code.
