Service Virtualization

I am using the think time setting in my VSI to control delays for my simulated transactions..  

I am using the variable name approach {{min}}-{{max}}, which works..but..

the time is ADDED to the elapsed time of the service BEFORE the  response..

I thought these VSI think time values should be TOTAL time.. 

my service takes 10ms.. I asked for 100ms in the VSI think time.. I got 110 ms.. 

I don't want to add code to do the adjustment calculation unless its needed

this is versions 9.1 and 9.5.1

There were a support ticket for this.

Resolution: Delay in the VSI counts the transaction processing time and VSE metrics report the response time with a slight wiggle. The response time what we see is client side which will have network delay on top of the VSE delay.

right. but if you want closer, you will have to customize the delay.. 

I wanted 100ms..(95% of the time)..  

I specified 100, but got 115. 

to get actual 100, I had to specify 83.

as measured by the client sender tool, on the same physical lan segment. 

we did not look at the VSE response time reports, cause we dont' care what it looks like inside the VSE, as we are trying to simulate reality for performance testing.
