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.

We've got two machines which are identical in every way, same hardware, same AIX, same TSM level, same options set, same storage pools, domains, everything except one has the DB and Log on local disk. On this box things run very slowly: expiration may take a week, filespace deletion creeps, and we see this as the normal behavior
