Tip
Setting
FilterLimit 1000
in
cupsd.conf
will not allow more filters to
run concurrently than will consume a total of 1000 virtual filter
cost. This is an efficient way to limit the load of any CUPS
server by setting an appropriate “FilterLimit” value. A FilterLimit of
200 allows roughly one job at a time, while a FilterLimit of 1000 allows
approximately five jobs maximum at a time.
