Quick Guide to Using Apache Benchmark (ab)
Updated: 2000.05.01 ab is a handy little utility for stress-testing. it allows you to pound a url, and gives some basic statistics at the end. useful arguments are: -c -- number of concurrent clients -n -- number of total requests -C -- a cookie string -A -- Authen info eg 'user assword'Eg: /usr/local/apache/bin/ab -c 8 -n 100 -A 'guest ass*word' \-C "User=id&4819; Pref=lang&en" \ "www.myhost.com/foobar.html" Start with low values of c and n, as you could slow your site down considerably; gradually increase them for more rigorous stress-testing. One potential issue is that ab doesn't tell you the statuses of the requests, just the number of failed requests. So, it will be hard to tell a server error from a redirection, etc.. |
