I had a similar problem a while back and took the opportunity to test 
various RDBMS.   I found that a product called TimesTen from Oracle was 
the fastest, followed by Microsoft SQL server, followed by Oracle 10 
Enterprise with bitmap indicies, followed by Postgres.  RSQLite had 
relatively poor performance and I had trouble persuading MySQL to 
optimize the query at all.   I did not try any column oriented database 
systems like Sybase IQ or Vertica, which should do better for the 
read-oriented workload.
