Job Performance Vs Running from Query Analyzer

I have a proc that takes 43 seconds to run if I run it from query analyzer. If I run it from a job it takes 17.5061 minutes.
The job command is EXEC [HYPERe]..[B33HiveMigration].
I cut and paste it into Query Analyzer and whosh. From the job it's a dog. Are jobs governed. No other variables to consider - on a standalone network using the same box. The proc performs a series of updates, deletes, and inserts.
Thank you for your help.Ideally, it should take around the same amount of time. But are there any
logs in the sqlagent.out that might point to some errors or weird behaviour?
