SETOBJACC and file performance

I am working with an application that maintains a copy of data from
several libraries, and uses a brute-force 'read all records and
compare' strategy.  Inside the CL that calls the RPG, the files that
are to be read from are specified in several SETOBJACC commands.  The
help for this command leads me to believe that this is set up to
accelerate the performance of database READs/WRITEs/UPDATEs.

Does anybody have any experience with this method?  Does it simply
allow larger record block sizes?  What are the pitfalls, and finally,
if I am updating files that have dependent logicals, is this safe?
