[Performance Testing Tool]-Siege

Advantages: RatioHttp_loadEasy to use, because the sameUrl.txtFile inHttploadSo it is easy to use.HttploadWorseSiegeFurther research is required.

Disadvantage: automatic creation is not allowed during installationSiege. LogFile, which must be created manually.

 

Overview:

Siege is a stress testing tool. As with http_loadparts, siegeis also a file that reads urls.txt. You can configure multiple users to access a Web site concurrently, record the response time of all request processes of each user, and repeat it with a certain number of concurrent accesses. This is more advantageous than executing stress tests on only one URL in apache.pdf. Siege supports basic authentication, cookies, HTTP and HTTPS protocols.

Installation:

# Tar-zxvf siege-2.72.tar.gz
# Cdsiege-2.72

/Siege-2.72 #./configure
/Siege-2.72 # Make

/Siege-2.72 # makeinstall

Basic usage:

Xxxxxxxxxxxx :~ /Siege-2.72 $ siege-C 5-R 10-F urlsdamai.txt/* concurrent five users, 10 iterations,-F indicates the list of URLs to be read */

** Siege 2.72

** Preparing 5 concurrent users for battle.

The server is nowunder siege... done.

 

Operation Result:

Transactions: 50 hits/* 50 times of server access, or 50 times of Processing */

Availability: 100.00%/* 100% success rate */

Elapsed time: 8.14 secs/* total time in 8.14 seconds */

Data transferred: 5.25 MB/* Total data transmission: 5.25 MB */

Response time: 0.19 secs/* Response Time: 0.19 seconds: display the network connection speed */

Transaction rate: 6.14 TRANS/SEC/* processes 6.14 requests per second on average, and the processing speed on the server side */

Throughput: 0.65 MB/SEC/* Average data transmission per second 0.65 MB */

Concurrency: 1.15/* the actual maximum number of concurrent users is 1.15 */

Successfultransactions: 50/* 50 requests are successfully processed */

Failedtransactions: 0/* failed to process 0 requests */

Longesttransaction: 0.46/the longest processing time is 0.46 seconds/

[Error]Unable to create log file: Permission denied/* When a non-root user executes a concurrent command, siege-C 5-R 10-F urlsdamai.txt, the siege log cannot be written to "siege. the log file is not created during make & make install. Therefore, there are two solutions, and the 1st solution to this problem is to manually create a "siege. log ", the 2nd method is to directly switch to the root user, after execution, this siege is automatically created. log File */

-G, -- get, pull down HTTP headers anddisplay

Transaction. greatfor application debugging.

-C, -- Concurrent = num concurrent users, default is 10/* Number of concurrent users */

-I, -- Internet User Simulation, hits urlsrandomly.

-B, -- benchmark: No delays between requests.

-T, -- time = numm timed testing where "M" ismodifier S, m, or H/* test execution time, for example,-T 1 m is 60 seconds */

Ex: -- time = 1 h, one hour test.

Between 1 and num. (not counted in stats)

-H, -- header = "text" add a header to request (can be requested)

-A, -- User-Agent = "text" setsuser-agent in request

 

Discussion/Question:

• What does "response time" in the test result mean?
• What does "concurrency" in the result mean?
