To access NT performance monitor data, the user who creates the infrastructure monitor with 
                  		  Silk Performance Explorer needs to be in the administrator group of the computer that you want to monitor. The execution server must also run under
                  that user.

As the processes in which transactions are executed are not stopped after scheduled executions, global variables within scripts
               remain valid. Therefore, it’s possible to define variables in 
               		begin transactions and use them to remember values from previous executions. Using global variables for project attributes, variables
               can be initialized in 
               		begin transactions and used throughout scripts.
