But prepare_cached/prepare has nothing to do with multiple connections.

If the query just hangs there in mysql, putting it into DBI is not going to fix
that. Are the columns indexed in the tables? If not, you've probably got it
doing nested full table scans. Try adding indexes to the tables on the join
columns.
Get the query to run in mysql before you ever try it

We are migrating our systems from Informix to Oracle. We have a lot of code

You need DBD::ODBC to access MS Access using Perl and DBI. It can be
downloaded from CPAN, or if you are using ActiveState, or PPM you can use
them to search, locate download and install this module.

If you have no indexes, I'm not at all surprised it takes that long or even
longer to get results from a join on MySQL on two tables with this many
rows. The join must be completed before results are returned,
The 'Best way' may not be Perl. Is this a one time shot, or something where
the two servers need to interact constantly?
If this is one time, or something that needs to happen only periodically, I
would recommend Data Transformation Services (DTS). That is part of the MS
