Simple jmeter Single http request & beanshell script generating hmac authentication.

[clintFortinbras]

Hi All, I am looking to increase our jmeter test throughput for the following scenario

a simple http request with beanshell script generating hmac authentication.

How can i speed up the authentication computaion ?

One thought that comes to mind is Pre-compute HMACS (300K ) and store them in the app.

Then when i go to run the 7K of threads, simply pull the authentication from a list.

Can any one help with suggestions around this ?
