Requests per second: 10.24 [#/sec] (mean) # throughput, number of requests processed per unit of time in 100 concurrent users. 10.24 times per second meanrepresents an average. the larger the value, the better.
Time per request: 9764.459 [MS] (mean) # user average request wait time , mean mean
Time per request:90.303 [MS] (mean, across all concurrent requests) #Average of actual run time per request
Transfer Rate: 5.55 [Kbytes/sec] received #平均每秒网络上的流量 to eliminate the problem of prolonged response time due to excessive network traffic

#并发请求CPUs are not processed at the same time, but are rotated on a per-request basis, so basically the first time per Requests is approximately equal to the second Time multiplied by the number of concurrent requests.
