    Analyzing load test results I see that in exported excel file  such parameter as "Time To First Byte per Interval (sec)". 
    Can you, please, give me more info about it and what is the difference between this parameter and "Average Time To First Byte".

    Thanks in advance

    Hello Leo,

    Here are the definitions of both parameters.

    Average Time To First Byte:
    An average (in milliseconds) of how long each user response took to received, from request to end of response.

    Time To First Byte per Interval:
    Total time (in seconds) across all virtual users from the moment a request was sent to the moment the response's header was received during this interval.

    I hope this clarification helps.
