Does php-fpm use more memory?
PHP-FPM has as a default configuration that uses more memory than necessary. It has spare php-fpm processes ready to go, taking up memory in case there is PHP code to process.
How much memory does php-fpm use?
Most requests used up to around 10 MB of memory, while a few used as much as 18 MB and a very very few (6 requests) peaked at 131 MB. (In this example those are probably cache clears.) A conservative approach would suggest an average request memory of 16 MB should be sufficient.
Does php-fpm cache?
PHP running as PHP-FPM By default, it will flush the entire cache, no matter how many websites you have running.
Is php-fpm necessary?
Conclusion. PHP-FPM is an efficient method on how to minimize the memory consumption and rise the performance for the websites with heavy traffic. It is significantly faster than traditional CGI-based methods in multi-user PHP environments.
How do I check PHP FPM memory usage?
total=0; for i in `ps -C php-fpm -o rss=`; do total=$(($total+$i)); done; echo “Memory usage: $total kb”; Memory usage: 0 kb ps -ef | grep php root 9435 1 0 11:42? 00:00:00 php-fpm: master process (/etc/php/7.0/fpm/php-fpm.
What is PHP-FPM service?

- Rightclick and select restart.
Is PHP-FPM better?
PHP-FPM is faster than traditional CGI-based methods, such as SUPHP, for multi-user PHP environments. It does not overload a system’s memory with PHP from Apache processes. PHP-FPM features include: Ability to start workers with different uid/gid/chroot/environment and different php.
Why is PHP-FPM faster?
“but php-fpm suppose to be much faster because it’s using FastCGI ” — fastcgi is just a SAPI, it does not make php itself faster or slower. But presence of fastcgi makes request transfer slower – since you need to connect and transfer a request, whereas with mod_php it’s in the same process memory space.

How to install php7.0-fpm and varnish?
Minimally, install php7.0-fpm and varnish from apt. Copy default.vcl from this gist into /etc/varnish. It should work as-is in this basic configuration, and is essentially a blank slate for future customization using the expressive Varnish Configuration Language.
What is Varnish cache and what does it do?
Varnish Cache is an open source frontend accelerator for the web or caching reverse proxy. It’s installed in front of your web server that handles HTTP requests and set up to cache the contents of responses.
Which is better, varnish or Nginx FastCGI cache?
WordPress plugins generally come out on top, excluding W3 Total Cache whose control panel is unwieldy. Although Nginx FastCGI caching is relatively easy to configure, it requires sudo privileges on the server. Varnish on the other hand is far more complex to set up due in part to the requirement for HTTPS termination.
How to reload the service unit of varnish?
Register the updated service unit with systemctl daemon-reload and restart Varnish with systemctl restart varnish. Now your static assets will be cached on disk, which should be a performance wash, and precious in-memory cache space will be reserved for dynamic content.
