Which kind of query do you want to run?
Queries that involve only a few rows should stay quite fast when you set
up the right indices.
However, queries that involve sequential scans over your table (like
average computation) will take years. Get faaaaaast I/O for this. Or,
better, use a multidimensional data warehouse engine. Those can
precalculate needed aggregate functions and reports. But they need loads
of storage (because of very redundant data storage), and I don't know
any open source or cheap software.
