测试脚本

# 主要命令，on Windows PowerShell
$env:A_summary='0x7db880f9b7ebf56ae271497ca98edc4743efec62f7228e77644940cc95d95263'

./ab -n 10000 -c 60 -T "application/x-www-form-urlencoded" -p C:\Users\dell\Documents\BlockChain_Research\可信计算\压力测试\windows\postfile.txt http://192.168.31.144:8060/v1/tee/ 

# postfile.txt内容 - 这里读取windows环境变量其实未生效，考虑到数据量不大，没有实质性影响，因此忽略了
ciphertext='A.secret'&summary=$env:A_summary&description='A_description'&owner=$env:A_pub

命令解释：对http://192.168.31.144:8060/v1/tee/ 地址做10000次的请求，60个模拟并发，并附带postfile.txt中的参数做post请求。

命令还可以加上-k参数，表示开启http长连接。

第一段是介绍ApacheBench 的版本以及证书；
第二段是实时监控目前测试了多少个请求；
第三段是请求网址服务端的一些基本信息，包括服务端软件版本，主机名和端口；
第四段是请求服务端的地址和响应数据的长度；
第五段是请求的一些结果信息，以下摘录部分重要信息予以解释：

标题	描述	结果	解释
Concurrency Level	并发级别	60	相当于有60人同时发起请求
Time taken for tests	测试总共花费时间	33.160722 seconds	秒
Complete requests	全部请求	10000	次
Failed requests	失败请求	0	非2xx http code，如404
Requests per second	吞吐量-每秒请求数，即tps	301.56 [#/sec] (mean)	平均每秒请求次数
Time per request	每次发出请求到接收到响应花费的时间	198.964 [ms] (mean)	平均每次请求花费毫秒数
Time per request	并发的每个请求平均消耗时间	3.316 [ms] (mean, across all concurrent requests)	平均花费毫秒
Transfer rate	传输效率	78.62 [Kbytes/sec] received 76.57 kb/s sent 155.20 kb/s total	平均每秒网络上的流量，可以帮助排除是否存在网络流量过大导致响应时间延长的问题

第六段是网络上消耗的时间的分解；
第七段是整个场景中所有请求的响应情况。在场景中每个请求都有一个响应时间，其中 50％的用户响应时间不超过 196 毫秒，80％的用户响应时间不超过 236 毫秒，最大的响应时间不超过 400 毫秒。

格式一致，不再介绍。但有一点值得关注，结果中Requests per second相比较短连接上升了大约42%左右。原因很好理解，因为长连接会减少连接释放和创建的消耗，这里从最后一部分的 Percentage of the requests served within a certain time (ms) 也能很明显的看出来，连接的平均存活时间都大幅度增加。
