Use AB for stress testing in Ubuntu

1. I recently started to use Apache big data for Data Optimization. Let's talk about the AB stress testing tool in Apache.

The program "AB" has not been installed. You can use the following command to install:

apt-get install apache2-utils   

The following are AB -- Help

SAGE: AB [Options] [http [s]: //] hostname [: Port]/pathoptions are: -N requests number of requests to perform-C concurrency number of multiple requests to make at a time-T timelimit seconds to Max. to spend on benchmarking this implies-N 50000-s timeout seconds to Max. wait for each response default is 30 seconds-B windowsize size of TCP send/Receive Buffer, in bytes-B Address to bind to when making outgoing connections-P postfile file containing data to post. remember also to set-t-u putfile file containing data to put. remember also to set-T-t Content-Type header to use for post/put data, eg.

'apache = 100 '. (repeatable)-H attribute add arbitrary header line, eg. 'Accept-encoding: gzip' inserted after all normal header lines. (repeatable)-A attribute add basic WWW authentication, the attributes are a colon separated username and password. -P attribute add basic proxy authentication, the attributes are a colon separated username and password. -X Proxy: Port proxyserver and port number to use-V print version number and exit-K use HTTP keepalive feature-d do not show percentiles served table. -s do not show confidence estimators and warnings. -Q do not show progress when doing more than 150 requests-l accept variable document length (use this for dynamic pages)-G filename output collected data to gnuplot format file. -E filename output CSV file with percentages served-r don't exit on socket receive errors. -H display usage information (this message)-Z ciphersuite specify SSL/TLS cipher suite (see OpenSSL ciphers)-f Protocol specify SSL/TLS Protocol (ssl3, tls1, tls1.1, tls1.2 or all)
-N: Total number of requests executed. The default value is 1.-C: number of concurrent requests. The default value is 1.-T: total time of the test, in seconds. The default value is 50000 s-p: data File-W during post: output results in HTML table format

The result of executing AB-N 5000-C 200 http: // localhost/test. php is as follows:
