snmptable doesn't call get_first and get_next. Thos are part of the handler/helper you are using in the agent. snmptable uses snmp GETNEXT commands to walk a table.

The iterator help is for unsorted data, which means the help has to search through all the data, starting at the beginning, to find the data needed to respond to a request.

Yes, the iterator helper is a poor choice for a large table. You should look at some of the other helpers which will sort the data, make it much faster to find a particular row for processing.
