Your code looks like straight DBI. The easiest way to make this a LOT faster is to make the whole operation one single transaction.

$dbh->do("SET autocommit = 0");
....
$dbh->do("COMMIT");

I took the above "SET autocommit = 0" from some MySQL code that worked in my app. If you commit every 1/4-1/2 million records or so, the performance will be fine. There can be other ways to start the transaction, perhaps BEGIN or other keywords.

I do find this map pretty ugly: 

map
{
   my($keys,$value)=split /\s*:\s*/,$_;
   $keys=~ s/\s//g;
   $info{$keys} = $value;
}split /\n/, $record;

#Don't use map when you mean foreach (or for)
foreach (split /\n/, $record)
{
  ....
}
