Use a replicated setup?

How about either:-
a) Size the pool so all your data fits into it.
b) Use a RAM-based filesystem (ie: a memory disk or SSD) for the
data storage [memory disk will be faster] with a Smaller pool
- Your seed data should be a copy of the datastore on disk filesystem;
at startup time copy the storage files from the physical to memory.
A bigger gain can probably be had if you have a tightly controlled
suite of queries that will be run against the database and you can
spend the time to tune each to ensure it performs no sequential scans
(ie: Every query uses index lookups).
