Depending on which version of the agent you are using,
this is controlled by either:

mibgroup/ucd-snmp/vmstat_solaris2.c:250:
   if (snmp_alarm_register(5, NULL, update_stats, NULL) == 0)

or

mibgroup/hardware/cpu/cpu.c:9
   static int _cpuAutoUpdate =  5;

mibgroup/hardware/cpu/cpu.c:39
   _cpu_cache = netsnmp_cache_create( 5, netsnmp_cpu_arch_load, NULL,



Changing '5' to '1' and recompiling the agent should increase the
polling frequency.

If you're using the newer code (hardware/cpu), it *might* be possible to
amend this via the nsCacheTable,  but I suspect it doesn't currently
work that way.
