http_load - multiprocessing http test client
http_load runs multiple http fetches in parallel, to test the throughput of a web server. However unlike most such test clients, it runs in a single process, so it doesn't bog down the client machine. It can be configured to do https fetches as well.
You give it a file containing a list of URLs that may be fetched, a flag specifying how to start connections (either by rate or by number of simulated users), and a flag specifying when to quit (either after a given number of fetches or a given elapsed time). There are also optional flags for checksums, throttling, random jitter, and progress reports.
二 安装三 使用# wget https://acme.com/software/http_load/http_load-09Mar2016.tar.gz
# cd http_load-09Mar2016
# make
$ ./http_load -h
usage: ./http_load [-checksum] [-throttle] [-proxy host:port] [-verbose] [-timeout secs] [-sip sip_file]
-parallel N | -rate N [-jitter]
-fetches N | -seconds N
url_file
One start specifier, either -parallel or -rate, is required.
One end specifier, either -fetches or -seconds, is required.
准备urls文件
$ echo 'http://localhost:80' > urls
