Are the spindle speeds equivalent?  15Krpm vs 10Krpm can make a big
difference.  Also does the non-local disk have writeback cache in the
controller?  This can speed up writes, and expiration and filespace
deletion do a lot of writes.

things run very slowly: expiration may take a week, filespace deletion
creeps, and we see this as the normal behavior
