Good news
 
Perhaps it is possible that you publish more detailed info of this test as an example. Providers handle they local data in many different ways (excel, access, whatever ...), but MySQL is pretty commonly available in shared institutional servers.
So having a good working sample of a well designed database schema (properly indexed) for providing massive DarwinCore data would be very useful as an example to follow (I mean an sql file with CREATE sentences for tables and indexes).
Just an idea
