When I run the command, other critical programs fail to respond causing
an 'outage-like' situation.
Normally, this is a time-of-day task and will run happily later into the
night, but I want to run it now.
What is the best way to set priority on my task in order to ensure it
completes as quickly as possible, but does not cause a situation where
other programs and their children can't respond?
generally single program could not make that - FreeBSD schedules tasks
well. in certain cases it may be like that.
For example - programs that runs for long time constantly and uses CPU
gets automatically "downgraded" so your newly run backup task can make
them really out of CPU power.
man nice
will help you - get your backup program priority down.
Actually i don't know if "downgrading" (called autorenice) can be disabled
for certain processes. If would make sense for - say - database servers.
Anyone know?
