. . .  workload performance for increasing users/load on the system. For small number of users, ext2 or ext3 may suffice but for large number of users, the limits of the IO subsystem are reached sooner than with raw and OCFS storage. The performance of the overall system depends on the type of application and for an Oracle database it usually depends greatly on the physical organization of data on disk. . . .
