Siege Simple Tutorial

Although Apache comes with a stress test tool AB, AB's functionality is too simple to simulate real web access, so we're going to use the more powerful web stress test tool--siege (the English original: Siege).

After installing siege, modify the siege configuration, find the Siegerc file, and then vim SIEGERC

Adjustment:

verbose = Falseconcurrent = 50delay = 1internet = Truebenchmark = True

Siege parameter Description:

*-C NUM

Set the number of concurrent users (connections), such as-C10, to set the concurrent 10 connections. The default number of connections can be viewed in ~/.SIEGERC, the instruction is concurrent = x, before we have adjusted the default concurrent connection is 50.

*-R NUM

(repetitions), the number of repetitions, that is, the number of requests per connection, setting this, you do not need to set-T. corresponding to the reps = x directive in the. SIEGERC configuration file

*-T NUM

(time), duration, which is the duration of the test, ends after NUM time, the unit defaults to points, such as-t10, then the test time is 10 minutes,-t10s, the test time is 10 seconds. The instruction in the corresponding. SIEGERC is time = x instruction

*-B

(benchmark), benchmark, if this parameter is set, then the delay time is 0. In. Siegerc we modify it to open by default.

*-F Url.txt

(file), which is the URL list file. The file = x directive in the. SIEGERC configuration file

Test Result Analysis:

The above is the result of 500 concurrent repeat Test 50 times the URL list in Shunz.net.url,

Analyze the test results in one of the following strips:
