Others have already responded to let you know pretty well how velocity works, 
but I thought it might be important to clarify that velocity has nothing to do 
with memory use.  If a space is set up with a velocity of 5 that does getmains 
for 50GB of storage, and another one with a velocity of 95 only getmains 5MB of 
storage, the velocity will have nothing whatsoever to do with how much storage 
the two spaces use.  It's only the relative importance of the spaces being 
executed, and not anything to do with their memory use.

Your original listing said that you were worried that the vendor space that was 
a lower velocity had more memory, but the amount of memory use is a factor of 
the memory that a space getmains, and WLM isn't really involved there.  

Although, when it comes to something that has a tremendous amount of memory 
allocated you don't want to cause thrashing by having it so low of a priority 
that it spends all it's time paging in and out and not much doing actual work.
