The Wdiff Utility lets you compare recorded Vuser scripts and replay results to determine which values need to be correlated.
To use WDiff effectively, you record the identical operation twice, and compare the scripts (or data files for WinSock). WDiff displays differences in yellow. Note that not all differences indicate a value to correlate. For example, certain receive buffers that indicate the time of execution do not require correlation.
For task details, see How to Search for Values that Need Correlation.
