Debug options

[Niklas Sorensson]

Hi,

I was wondering how to turn off the debug options mentioned in /usr/src/UPDATING.
So far, I only found these kernel options:

options        KDB
options        DDB
options        GDB
options        INVARIANTS
options        INVARIANT_SUPPORT
options        WITNESS
options        WITNESS_SKIPSPIN

Are there any other options that affect performance? The note mentions
malloc-debugging flags, but I don't know how to turn it off.

(sorry if this is a FAQ)
