Using xhprof.com to analyze PHP performance

Today, I stumbled across Www.xhprof.com's ability to analyze PHP code remotely, with the following general steps

1. Enter www.xhprof.com, click on the upper right corner to register and login, the left side of the site explains how to install the test xhprof, I use the right chart mode, so that can save the local build steps.

2. Install the xhprof extension locally, this is the same as the normal extension

  wget http://pecl.php.net/get/xhprof-0.9.3.tgz  tar zxvf xhprof-0.9.2.  tgz  cd xhprof-0.9.2/extension/  sudo phpize  ./configure--with-php-config=/usr/local/php /bin/php-config  sudo make  sudo make install  or yum install PHP-xhprof

3. Download the embedded script provided by www.xhprof.com and include it in the page you want to test

wget ' http://www.xhprof.com/lib_xhprof_com.php?username=***&&password=**************** '-o/tmp/lib_ xhprof_com.php contains include_once('/tmp/lib_from_xhprof_com.php ') at the beginning of the test page; # if it's on the line, it's better to add probability if (Mt_rand(1, +) = = 1)    {include_once('/tmp/lib_from_xhprof_com.php ');}

4. Click to access the chart mode http://www.xhprof.com/charts.php to see the performance information of your website.

5. It is convenient to sort performance information, filter URLs, etc.

6. You can save the performance information that you feel is characteristic (the website only stores 300 of the performance information without selecting save, redundant automatic cleanup), and of course it can delete the performance information.
