- We have a couple of HP boxes with Oracle and a few Unisys machines with
- a DBMS called MAPPER. We have run test with and without raw partitions. The
- test showed an average improvement of aprox 15 - 20 % in speed when we used
- raw partitions. But we decided to go for normal filesystems 'cause the problems
- of back-up and restoring raw-partitions doesn't fit into our back-up
- scheduling.
-
- Summary:
- raw is faster, but normal filesystems are better manageable.
