Ok, so maybe someone on this group will have a better idea. We have a database of financial information, and this has literally millions of entries. I have installed indicies, but for the rather computationally demanding processes we like to use, like a select query to find the commodity with the highest monthly or annual returns, the computer generally runs unacceptably slow. So, other than clustring, how could I achieve a speed increase in these complex queries? Is this better in mysql or postgresql?
