Slow Table in SQL Server? Re-Index it!
One of my sites has started getting sluggish lately. I thought it was just that the traffic was increasing and so I should optimize my code. Then, in the last couple of weeks, I had a 3AM scheduled task crash a few times. This weekend, I had a simple query with one row and one column take several minutes to execute even from the SQL Server Query Analyzer. This is getting weird!
I found out some other stuff helping me with some of my very large tables. You can see that on my blog: http://sqlgott.blogspot.com
