Visual Round Trip Analyzer (VRTA) is a tool that helps the SharePoint Administrator identify what is being downloaded at a web page level.
One of the biggest complaints from users is the response time.
VRTA excels in showing the network round trip relationship between the client and the server.
This is also critical to the well-being of a farm. While an administrator can optimize the server response, there are several other parties that can inadvertently be working against this:
All of these listed parties create solutions using SharePoint Designer, Notepad, and possibly Visual Studio, and the administrator would have no knowledge of this. But in the end, the administrator is the person who will get the support call.
Using VRTA, the administrator can identify the bottlenecks and involve the right parties.
You must have VRTA loaded on a PC (free download from the Microsoft Download Center). Netmon 3.4, also a free download, needs to be loaded on the PC. These tools should not be run on servers but on local machines. No special permissions are needed and it can be run against a public site.
VRTA uses Microsoft Network Monitor 3.4 packet analyzer as its foundation. Visually, it shows files and packets, along with the round trip information that occurs between a client and server.
When evaluating page loads, several factors should be taken into account:
Using the four tabs, Main Chart, Statistics, All Files, and Analysis, the data the page is retrieving and loading can be seen in detail. In the preceding screenshot, every file that is loaded shows how long to load, the port, the type of file, a status code, and size.
VRTA also has an Analysis tab that acts as a best practice guide. It grades the files and page on several basic factors such as an average file size rule, white spaces rule, and image clustering rule. Using a color-coded scheme, it makes recommendations to help you improve performance.
Finally, every time a recording is made, it is saved in a directory by default, whose path can be seen in the title of the VRTA application.
