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. mailing list Received on Mon 22 Oct 2007 - 23:09:39 GMT
