Application Performance Analysis
To analyze the WAAS traffic, choose Analyze > WAN Optimization > Application Performance
Analysis.
The charts available on this page are:
• Transaction Time (Client Experience)
• Traffic Volume and Compression Ratio
• Average Concurrent Connections (Optimized vs. Passthru)
• Multi-Segment Network Time (Client LAN - WAN - Server LAN)

Transaction Time (Client Experience)

This chart displays the average client transaction time. One line represents pass-through traffic (in which
optimization is turned off), and the second represents optimized traffic. After setting up optimization for
a certain period, you can compare the two lines and see where the vertical drop in the chart occurs. The
data is shown in milliseconds.

Traffic Volume and Compression Ratio

This chart shows the bandwidth reduction ratio between the number of bytes before compression and the
number of bytes after compression.

Average Concurrent Connections (Optimized vs. Passthru)

This chart shows the number of concurrent connections during a specified time and can be used for
capacity planning.

Multi-Segment Network Time (Client LAN - WAN - Server LAN)

This chart shows the network time between the multiple segments. The data is shown in milliseconds.
Conversation Multi-Segments
Use the Conversation Multiple Segments window to monitor WAAS traffic. This window provides a
correlation of data from different data sources, and allows you to view and compare response time
metrics from multiple WAAS segments (data sources). You can access this window from Analyze >
WAN Optimization > Conversation Multi-segments.
The Response Time Across Multiple Segments window shows response time metrics of the selected
server or client-server pair from applicable data sources.
