TSQL - Optimizing Full Text Search query with temp table - sql-server

Question

To make it short I have a full text search query that does a company search on a single table. Once the search is complete I pull extra stats from the result such as Top 5 titles, top 5 locations etc...
How can this query be optimized it currently takes about 5 seconds to execute on < 25,000 rows and based on the execution plan its mostly on the last 3 select statements.
SQL SERVER: 2005. I can upgrade to 2008 but I've heard there are more performance issues with SQL 2008.
Help is greatly appreciated.

IF (#LocationNear is not null) BEGIN

END

Answer 1

Your execution plan results may be deceiving. In SQL 2005, the fulltext engine is an external service, so SQL cannot accurately report on what's happening in that piece of the puzzle.
I'm not sure what performance issues you've heard of in 2008, but in 2008 the fulltext engine becomes fully integrated with the database, making it much more efficient in a case like yours where you're joining a database table against a set of fulltext results. If upgrading is an option for you, I'd encourage you to pursue that option.
