Read what Brother Niao wrote about making your PHP7 faster (GCC PGO, and then start compiling it yourself.

sapi/cgi/php-cgi -T 100 /var/www/htdocs/wordpress/index.php >/dev/nul
In this step,

sapi/cgi/php-cgThis file cannot be found in /php-7.0.10/sapi/cgi

Steps to compile PHP7 with GCC PGO optimization
Use PGO (Profile Guided Optimization) to optimize specific scenarios based on profile data, which can bring a 10% performance improvement.
1. First compile PHP7 for the first time, and let it generate profile data executable file, where prof-gen is a parameter unique to PHP7's Makefile:
make prof-gen
2. Use php-cgi to run the WordPress homepage 100 times to generate some profile information in the process:
sapi/cgi/php-cgi -T 100 /home/huixinchen/local/www/htdocs/wordpress/index.php >/dev/null
3. Compile the PGO optimized executable file according to the profile information:

<code>make prof-clean
make prof-use && make install</code>

Copy after login

Among them, sapi/cgi/php-cgi is a binary program compiled for the first time. After make prof-gen, you can see it in the directory php-src/sapi/cgi/.
