The File Access Protocol indicator shows one of the following:
Indicates the Win32 file access API is being used. This indicator is
Win32 File
displayed for local disks, MediaNetwork storage that has been
API
mounted, and network file shares.
AECIFS Indicates the performance monitor has detected that AECIFS is
present and the storage specified by the Path to Test setting is
supported by AECIFS. AECIFS is a high-speed protocol for
transferring data to and from the MediaNetwork storage.
The I/O Operation indicator shows one of the following:
The current mode of testing is Read operations.
(Reading)
The current mode of testing is Write operations.
(Writing)
Test Results Graph
The Test Results graph plots results measured over time. It is particularly
useful when you want to observe trends or patterns in performance.
For example, if another process is running that creates a periodic high demand
on the storage subsystem being tested, you might see this as a periodic drop in
observed throughput in the Test Results graph.
The Test Results graph shows the following:
Average The average throughput or bandwidth (in MB/s), plotted over time.
throughput
The calculated throughput or bandwidth (in MB/s) for recent I/O
Recent
operations, plotted over time.
throughput
The peak latency for individual I/O operations (either reads or
Peak Read or
writes) that have been completed over a short period of time. A
Peak Write MS
high measurement indicates a longer period of time was needed for
the operation to complete.
Because only the highest (peak) measurement over a short period
of time is displayed, a single high peak could be accompanied by
many low-latency operations that do not appear in the graph.
