perl threads will not make your program faster on a CPU with more cores. Someone recently tested it and the perl implementation of threads is actually making it worse on multi-core machines in most cases

Better use real processes and for example the module MLDBM::Sync to make concurrent access to it reentrant.

Also possible would be using a real separate database engine like mysql or postgres. This would already split the task into two processes and concurrent access would be handled completely by the database
