    No, you don't break a table up because of size. That violates one of the prime directives of database design.

    (2.5 million records isn't particularly large, but backing them up on a slow host is slow.)

    if it is slow then you need to optimise your querys. mysql can handle easily this many entries.

    Export and import don't depend on optimization or indexes - it's just slow for large databases on slow computers. But it doesn't affect the user experience.

    Optimization (of both the database and the queries) and the proper index design will speed up queries.
