SET STATISTICS TIME ON does not give consistent execution time.

bolshie6 asked:

I used SET STATISTICS TIME ON to find the execution time of a set of SQL queries. Each time i execute the query, i get a different execution time.

I cleared Cache before each execution. But still i don't get a consistent Execution time. The first time i executed the query and got 39ms as the total execution time. But the next time i executed the same set of queries i got 486ms as execution time. i'm not sure if i'm interpreting it in the wrong way.

What should i do?
