To view the selection of standard tests, click Standard Tests in the Avid
Performance Meter Settings dialog box.
Transfer Size
(KB)
This option controls the amount of data the test utility attempts
to read or write during a single I/O.
Transfer Rate
(KB/S)
The utility can attempt to perform I/O at a variety of fixed
transfer rates. This is useful for simulating the behavior of
applications that have a known data rate.
A special unlimited transfer rate setting is also available.
When you select the unlimited transfer rate, Avid Performance
Meter performs I/O operations as fast as possible while being
affected by all aspects of the total system being exercised.
Max File Size
(MB)
This option controls the maximum size of test data files
created for Reads or Writes. This option might affect
throughput measurements. For example, at any given data rate,
a smaller file is opened and closed more often than a larger
file, creating more overhead.
Use named
common file for
Reads
This option changes the way that the Path to Test parameter is
used, and the option is intended for advanced users only. When
you select this option, the Path to Test parameter must specify
a full path, including a file name. The test utility uses the
named file for its Read tests.
The utility creates the file if it does not exist and deletes it at
the end of testing. For this reason, the named file should not
already exist unless you want it to be deleted when the test is
completed. With this option selected, you can run Avid
Performance Meter on multiple clients simultaneously and
supply the same file name.
This allows Avid Performance Meter applications running on
multiple clients to read a common file. (The file is created as
needed, and the last Avid Performance Meter application to
stop deletes the file.)
