Suggest you investigate the following modules:
Storable http://search.cpan.org/~ams/Storable-2.15/Storable.pm
DBM::Deep http://search.cpan.org/~rkinyon/DBM-Deep/lib/DBM/Deep.pm
I'm using DBM::Deep in a project to store thousands of hashes elements (that include hash elements) and it seems very fast.
