There is evidence that sending jobs twice as fast (by defining two swift 
sites for teraport) made twice as many jobs run. These would be counter to 
the argument that there is a max node count and supportive of there being 
some long scheduling delay in the LRM, I think.

I guess increasing the jobThrottle to a larger number would therefore get 
more jobs in the queue and more jobs run, but putting more node on the 
head node.

Xueyuan, add this line to one of your site definitions: (but not both)

<profile namespace="karajan" key="jobThrottle">0.5</profile>

then make a run and send a log.
