Are you asking about overhead of DDB or all debug options?
all. invariants, witness etc.
I don't think that DDB support can be accounted for slowdown.
As for the rest, it's hard to say. I guess it depends on your workload,
also I never performed any benchmarks to compare this and I'm unaware

Have you proven beyond reasonable doubt that there is no filesystem
corruption or silent filesystem corruption due to bad hardware?
after last crash fsck_ffs found nothing suggesting such a case.
Actually the only change i made to this system (running flawless close to
two years) is upgrading
i've got third crash third week in a row.
Every time in sunday after 18:00, every time with rsync process (which
means rsync based backup that is done every day, not just in sunday!),
Is it the same rsync everyday, including sundays, or the sunday rsync is
different?
the funny part is that
There is nothing in cron that is done at sunday.
i don't run "periodic" stuff in /etc/crontab
Compile the kernel with the following:
makeoptions DEBUG="-O0 -g"
options KDB # Enable kernel debugger support.
options DDB # Support DD

this <2 minute boot time that will follow doesn't matter as it doesn't
crash every now and then - it is nothing compared to the fact you have to
travel there.
Please give me an idea what to chec
