lnmp - Doubts about PHP7 GCC PGO compilation

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

Then, since it is actually lnmp, should I use a file under sapi/fpm/ for training?

But novices really don’t know how to play this step. After searching, there are no foreign devil tutorials, and almost all of them are copied from Brother Niao's articles. The official PHP website also has instructions for this method. . .

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:

make prof-clean
make prof-use && make install

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/.
