I'm somewhat a newbee on this database but some observations:
As your table grows (and indexes) INSERTS will definitly slow because of the indexes.
Consider MySQL's version of Oracle's partitioning and using MERGE TABLES "feature". Just
remember that if you change 1 table, all of them have to be rebuilt the same way.
Consider compressing the tables (Making them READ ONLY) with the MyISAM engine. The
updating table (current one) would not be available since it could not be compressed.
