In general "fork no" should not be combined with installs of any size,
as this could cause dips in the graphs more easily.

snmp in many is quite CPU-heavy to interogate an could cause the CPU-maxing.

There is a posibility of swapping snmpget and snmpwalk with snmpbulkget
and snmpbulkwalk if you have those programs - they have less overhead.
There is a need for writing recomandations for writing efficient snmp
plugins, but this has not been done.
