tideways+toolkit performs performance analysis on php code

Toolkit is a command line tool for performance analysis officially provided by tideway. If you only develop and debug interface performance locally and do not want to install xhgui, then using toolkit is enough.

Install

Install tideways extension

git clone https://github.com/tideways/php-xhprof-extension.git
cd php-profiler-extension
phpize
./configure
make && make install

Add to php.ini

extension=tideways_xhprof.so

Restart php-fpm

service php-fpm restart

toolkit installation

go get github.com/tideways/toolkit
# 安装graphviz
# macOS
brew install graphviz
# ubuntu
sudo apt-get install -y graphviz

Set alias

alias tk=toolkit

tideways toolkit

Code Buried Point

Add

if (extension_loaded('tideways_xhprof')) {
    tideways_xhprof_enable(TIDEWAYS_XHPROF_FLAGS_CPU | TIDEWAYS_XHPROF_FLAGS_MEMORY);
}
// 你的代码
application();
if (extension_loaded('tideways_xhprof')) {
    $data = tideways_xhprof_disable();
    file_put_contents(
        sprintf('%s/app.xhprof', '/path/to'),
        json_encode($data)
    );
}

to the program entrance to execute the code , and then /path/to/app.xphrof

Performance Analysis

tk analyze-xhprof /path/to/app.xphrof

The default performance analysis indicator is wt_excl , other indicators include

1.wt call duration, including sub-functions

2.excl_wt call duration, excluding sub-functions

3.cpu CPU call duration, including Subfunction

4.excl_cpu CPU call duration, excluding subfunction

5.memory memory consumption (bytes), including subfunction

6.excl_memory memory consumption ( Bytes), excluding sub-functions

7.io io duration, including sub-functions

8.excl_io io duration, excluding sub-functions

Generation performance The indicators displayed in the bottleneck chart

tk generate-xhprof-graphviz /path/to/app.xhprof
dot -Tpng callgraph.dot > callgraph.png

#1.Function name

2.Inc Function running time, including sub-functions

3.Excl Function running time, excluding sub-functions

4.total calls Total calls
