I. Webbench

1. Install webbench-in Ubuntu to support Get,head and other requests, but does not support post requests

wget http://blog.zyan.cc/soft/linux/webbench/webbench-1.5.tar.gztar zxvf webbench-1.5.tar.gzcd webbench-1.5make && make install

2. Test Demo

webbench -t 5 -c 2 http://google.com/   >2个并发用户共同请求5秒

3. Test results Analysis

2. Benchmarking: GET http://google.com/ ＃GET方法请求谷歌
4. 2 clients, running 5 sec. #2个用户，运行5秒
8. Speed=4296 pages/min, 38664 bytes/sec. #4296个页面每秒，38664 bytes每秒
10. Requests: 358 susceed, 0 failed. ＃358次请求成功，0次失败

Two. Ab1. Install ab-in Ubuntu support post, get, head and other methods

sudo apt-get install apache2-utils

2. Test Demo

ab -n 500 -c 2  http://www.google.com/   >2个并发用户共同请求个数500个。

3. Test results Analysis

2. Server Software: gws ＃服务器信息
4. Server Hostname: www.google.com ＃测试地址
6. Server Port: 80 ＃测试端口
10. Document Path: / ＃测试文档路径
12. Document Length: 390 bytes ＃测试文档大小
16. Concurrency Level: 2 ＃并发数量
18. Time taken for tests: 6.752 seconds ＃测试消耗时间
20. Complete requests: 500 ＃完成的请求数
22. Failed requests: 0 ＃失败的请求数
24. Non-2xx responses: 500 ＃HTTP响应数据的头信息中含有2XX以外的状态码的请求数
26. Total transferred: 566000 bytes #总传输数据大小
28. HTML transferred: 195000 bytes #总传输html数据大小
30. Requests per second: 74.05 [#/sec] (mean) ＃吞吐量，每秒处理平均请求数
32. time per request: Span class= "lit" >27.007 [ms (mean #每个请求平均等待时间
34. Time per request: 13.504 [ms] (mean, across all concurrent requests) ＃服务器每个请求平均处理时间
36. Transfer rate: 81.86 [Kbytes/sec] received ＃平均每秒流量数
40. Connection Times (ms) ＃下面为时间花费的分布（连接、处理、等待、总数）
42. min mean[+/-sd] median max
44. Connect: 1 1 0.2 1 2
46. Processing: 22 26 7.6 25 150
48. Waiting: 22 26 7.6 25 150
50. Total: 23 27 7.6 26 151
54. ###下面为每个请求花费时间的分布
56. Percentage of the requests served within a certain time (ms)
58. 50% 26 ＃50%在26毫秒之内
60. 66% 27 ＃66%在27毫秒之内
62. 75% 27
64. 80% 27
66. 90% 28 ＃主要看这个参数，90%在28毫秒之内
68. 95% 29
70. 98% 36
72. 99% 52
74. 100% 151 (longest request)

To add data to the request header, as follows:

1. ab -H "Cookie: key=value;key2=value2" ...

4. Use AB for post requests

1. ab -c 1 -n 100 -T ‘application/json‘ -p data.json http://www.google.com/

The test results are not posted, and one more obvious result:

1. Total body sent: 15900 ＃body总的发送量
