Setting Up Your Test
61
File Access Method
The Avid Performance Meter can support more than one interface or protocol
for accessing data. This option allows you to control which interface is used.
Select one of the available settings:
t
Automatically select
— Automatically select a protocol for testing the
selected path. Generally, the utility selects AECIFS if it is supported, or
Win32 File API if AECIFS is not supported for the specified path.
t
Win32 File API
— Use the Win32 File API for data file access, even if
AECIFS is supported.
t
AECIFS
— Use the AECIFS interface for data file access. If AECIFS is
not supported, the utility does not automatically perform file I/O using the
Win32 File API. Instead, the test shows one or more errors in the Errors
section of the Results area.
Reads vs Writes
The Avid Performance Meter supports testing that focuses on Reads, Writes,
or that alternates between Reads and Writes. Select one of the test modes:
t
Writes Only
— The utility Writes test data files and measures the
throughput obtained during Write operations.
t
Reads Only
— The utility Reads test data files and measures the
throughput obtained during Read operations.
n
One or more test data files are written as sample data for testing;
however, the Writes required to set up the test are not included in the
throughput measurements.
t
Reads and Writes
— The utility alternates between Read and Write
tests. Approximately half of the test duration is allocated to reading, and
the other half is allocated to writing.
Transfer Size
This option controls the amount of data the test utility attempts to Read or
Write during a single I/O.
Transfer Rate
The utility can attempt to perform I/O at a variety of fixed transfer rates. This
is useful for simulating the behavior of utilities that have a known data rate.
A special Unlimited transfer rate setting is also available. When you select
the Unlimited transfer rate, the 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
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.
