When you say "preliminary request to retrieve" the number of rows in the
table, does that mean the agent has to provide that information, if it is
not defined by the agent, that means this approach is not doable, right?
By the way, I am using snmp_synch_response for BULKGET request, is there
something like snmp_asynch_response that I don't need to wait on it?

That probably depends on the structure of the MIB table(s).
The most efficient approach for your application would be to
issue a single request for *all* of the rows in each table.
That assumes you know in advance how many rows there will
be - which may involve a preliminary request to retrieve this
information.
It may still take a long time, depending on how the agent
has implemented those particular tables. If the agent is
relatively inefficient, then improving the client side won't
make much difference.
