Five to ten *minutes*?
No - that is WAY too long to deal with using an "on-demand" model!

I'd suggest that your best approach would be to periodically dump
the contents of the CORBA service into a text file or local database,
using a mechanism *external* to the SNMP agent.
   The MIB module can then report the information from that
"external cache" (with minimal delay), rather than having to wait
for the (internal) cache loading mechanisms to retrieve it on demand.

You'll always have to strike a balance between the overheads of
populating a data cache, with the time you keep this cache valid for
(and hence how out-of-date the information is).   That holds whether
the cache is held within the agent or externally.
   But I'd suggest that running a cron job to dump the data once or
twice an hour (or something similar), would be a reasonable starting
point, given the length of time you say it takes to load.
