I want to analyze the detail transaction response time report, as I know, the default report only contain minimum, average, deviation and maximum time. I need to know how many transaction taken (percentage) is under the maximum time.

For example I have 10 transactions, the performance report show me that the average transaction time is under 1 second, but the maximum time is 2.5 seconds, I want to know how many transaction is >= 2 seconds.

Could anybody help me about it.
