Web Stress test Tool Http_load

Introduction

• Http_load is a performance measurement tool based on Linux and UNIX platform.

• It runs in parallel multiplexing to test the throughput and load of Web servers, and to test the performance of Web pages

• But unlike most stress testing tools, it can run in a single process, typically not killing clients

• You can also test site requests for HTTPS classes

Summarize features and weaknesses

Characteristics:

• Simple, easy-to-start based on command line

• Compact and lightweight, after decompression since less than 100KB

• This tool is open source, free of charge

Disadvantages:

• Performance tests for Web pages only, not for access to the database

• Limited test results analysis

• Platform-dependent Linux (no windows)

In addition to the "Http_load" Web stress test tool, there are more powerful webbench, AB, Siege and other web testing tools

　　Main parameter Description:

• -parallel Shorthand-P: means the number of concurrent user processes

• -rate Shorthand-r: meaning the frequency of visits per second

• -fetches abbreviated-F: Meaning total number of accesses

• -seconds shorthand-S: meaning Total access time

• As long as you use the Http_load command,-parallel or-rate must fill in a

• As long as you use the Http_load command,-fetche or-seconds must fill in a

• Url_file represents your URL file path, url file is a text file, which fills in the URL you need to stress test, can be one can also be multiple

• 1044 requests, max concurrent Number 30, total transmitted data is 188674000 bytes, run time is 60 seconds, Focus: Total requests, maximum number of concurrent processes

• Average number of data transferred per connection, equal to 188674000bytes/1044 requests = 180722

• The number of requests per second to respond is 18072.2, the amount of data passed per second is ..., concerns: The number of requests per second (corresponding to the number of users per second in the LoadRunner)

• The average response time for each connection is 66.3438msecs, maximum response time 1066.13 msecs, minimum response time 15.677 msecs, Focus: Average response time per connection (corresponds to response time in quicktestprofessional, per-connection response user times)

• Represents the HTML status code that opens the response page, 200 indicates a successful response, or if the 403 has too many types, it may be important to note if the system is experiencing a bottleneck
