BCP performance issue

$

All,

I would like to clarify on couple of BCP issues that I'm facing

1. BCP xxx queryout -S xxx -T -N -m 0 is executing very fast when I run using my ID in command prompt, but when I execute the same as a JOB, it is using long time ex. compare between 1 sec and 3 hrs. I tested for a source table that is Queried with 0 rows to confirm and it happens like this. What could be the reason.

Executing the same Q in managment studio returns within seconds as well

2. Source server I/O contention + same table queried for BCP with different filters from multiple servers. Will this scenario cause BCP out to be slow. Note that IO is limited to the server capability, but would like to understand the contention caused to SQL opertaion by having such scenario.

Please consider 1 & 2 as two different problems and not at same time. Thanks for time/clarification.

Regards
