How to find the RAM memory footprint of TruClient Vusers?

• TruClient is a GUI based Loadrunner protocol. 
• One of the major setbacks of this protocol is its 1 vusers consumes a lot of physical RAM memory. Thus limiting the Vuser allocation to Load Generators.

In this post we will discuss about How to find the RAM memory footprint of TruClient Vusers?

• First create a TruClient Script for your desired flow.
• Then add the script to controller and assign 10 Vusers to it and start the run
• Go to --> Task Manager --> Performance Tab --> Open Resource Monitor --> Memory Tab. Here you can see the list process that are running and their memory usage.
• TruClient Vusers use browsers to execute the script and you can find a bunch of browser exe processes opened up. In our case it is firefox.exe.
• Check the working set column which shows RAM memory usage for each exe process i.e each Vuser. In our case each Vusers needs around 200 MB of memory.
• Based on this you can calculate the amount of RAM needed for other OS based activities and the amount of RAM needed for our execution and distribute the Vusers accordingly.
