Hi Robert,
Other than the removal of whats below from the kernel, what
other adjustments should be made to make more accurate comparisons ?
# Debugging for use in -current
options KDB # Enable kernel debugger support.
options DDB # Support DDB.
options GDB # Support remote GDB.
options INVARIANTS # Enable calls of extra sanity checking
options INVARIANT_SUPPORT # Extra sanity checks of
internal structures, required by INVARIANTS
options WITNESS # Enable checks to detect
deadlocks and cycles
options WITNESS_SKIPSPIN # Don't run witness on
spinlocks for speed
---Mike
