Using xhprof (PHP) extension for WEB performance analysis

I’ve been a little busy at work recently, often working overtime and occasionally staying up all night. But in the end, the popular Weibo "Mixed Stream" was successfully launched in full. However, from a performance perspective, there is still a lot of room for improvement.

The following is about using xhprof to analyze WEB performance.

Install xhprof extension:

Official documentation is better than anything => http://php.net/xhprof

Note: If you want to use xhprof drawing, you need to turn on the system default disabled function.

1	;disable_functions = phpinfo,system,exec,shell_exec,passthru,proc_close,show_source

Deploy xhprof Running environment:

After the above configuration, xhprof will output a report file after you run the project. However, the contents of this file are serialized arrays. Therefore, it is necessary to build a WEB environment that can read the data file.

Here is a code for the xhprof environment: http://pan.baidu.com/s/1bnLvmrl

After that, by accessing the xhprof environment, you will see the following report interface.

xhprof file list (/xhprof_html/list.php)

xhprof report in icon form (/xhprof_html/index.php)

• Function Name Method name
• Calls Number of calls
• Incl . Wall Time The execution time of this function (including the time of other internal function calls)
• Excl. xhprof report (/xhprof_html/callgraph.php) Some points to pay attention to:
The same method has been called too many times (maybe caused by unnecessary loops)

Whether the time consuming falls on the external interface (will Affects TPS – number of requests per second)

Is there excessive memory consumption (will affect computing efficiency)
