I will repeat my suggestion from yesterday. Use one of the mib2c templates generated with '-S cache=1' That will produce code that uses a local cache, with a 'load' routine, which will be called when the cache is "too old". If you set the timeout for the cache to be 0, then the data will be reloaded for every single new SNMP request. But note that this is every *request* - not every command. A single 'snmpwalk' command will trigger a whole sequence of GETNEXT requests, each of which will re-load the cache. That's why I think you might be better off with a cache timeout of a few seconds. But experiment - altering the timeout is a trivial change (and can even be done on the fly). No code changes are needed. Get something working using the cache first, and then worry about tuning the cache frequency.
