Performance aspects - tuning

An important factor in the performance of a UTM application is the efficiency with which openUTM can access the KDCFILE, particularly in the case of high transaction rates. With a large configuration, i.e. a large KDCFILE, it is recommended that you optimize the access times. This can be achieved in two ways:

• splitting the KDCFILE (see below)

• KDCFILE on raw-device (only on Unix and Linux systems, see "KDCFILE on raw-device (Unix and Linux systems)")

• KDCFILE on stripe set (only on Windows systems, see "KDCFILE on a stripe set in (Windows systems)")

On BS2000 systems, you can also use the HIPERFILE concept to optimize performance, see the manual "BS2000 OSD/BC - Introductory Guide to DMS".
