SOS_SCHEDULER_YIELD

I have a job running in 2 separate environments. In the first it runs very quickly (~5 seconds), however in the second it runs it takes MUCH longer (~5 minutes). These two machines have identical hardware and similar load. When I look at sys.sysprocesses to see what else is running, the long running machine always has the job step listed as SOS_SCHEDULER_YIELD as its wait_type. I know this is a natural yield for the step, but I don't think it should be yielding for this long, especially if nothing else is running. I have no idea where to look or what to change on this one. Any help would be greatly appreciated.

Thanks.
