[ or from cygwin use this directly:

Notes
I am using cygwin on windows here, hence the use of curl inside a windows batch file!
I did get this technique in detail from here:
https://stackoverflow.com/questions/18215389/how-do-i-measure-request-and-response-times-at-once-using-curl
In practice:
I do have one issue in my case and I probably have to resort to JMeter here, just to make enough calls to get consistent numbers - I can't be sure how much of this variability is due to data caching and how much is due to data lookup and server lag etc. A proper JMeter test would allow us to run for longer and numbers settle down properly. This could be important for management reports etc. (to be fair, this call does bring back a lot of data)
