The main focus is on three values:
Requests per second : QPS, reaction server concurrency performance, throughput. How many concurrency connections are supported per second
Time per request: an average of 100 concurrency connections in this case
Time per request : The average number of times per connection is the duration of a concurrency connection in this example, and the value equals the reciprocal of the first value above
How to find the number of supported concurrency for a site:
The general- n parameter to maintain 1000 unchanged, the- C parameter from small to large test (but not more than- n value), when the QPS value will be small, then become smaller, a parabolic trend, the highest value in the trend is the site can be supported concurrency Volume
