Yes, but you could write a Perl script that loads the SNMP library
once, and then does your every-five-minutes stuff in an endless loop.

For me, snmpget has significant startup overhead as well, because it
reads and parses a default set of MIB files.  Since you use a numeric
OID, you could prevent that by setting the environment variable MIBS
to the empty string when calling snmpget.  Possibly you'd have to
fully qualify the OID then (.1.3.6.1.2.2.1.10.2 2.2.1.16.2).
