in reply to Comparing DBI records
why don't you bulk insert the DBF data into a Mysql table and do the comparison with sql?
It seems like that you are doing equi joins;if that is so, then you can use a HASH table structure which is ideal for exact key retrieval.
you insert the DBF data into a table hashed on the keys and also make a HASHed secondary index on the keys of the Mysql table, which will be used for the joining
