Anyone have an idea of how to speed up CiviCRM PHP execution time ?
I'm an administrator of CiviCRM on Wordpress production set-up, and I find it too slow. I've conducted a little investigation using NewRelic and the whole execution time of (around 2,000ms per request in average) is due to Php execution. All the requests below are CiviCRM's (all URLs are of this type /wp-admin/admin.php?page=CiviCRM)
I'm running an SSD server with [email protected] + 7G RAM, with only one Wordpress&CiviCRM running on an Ubuntu 16.04, Php5.6, MariaDB, Nginx, Memcached, and FPM with 25 workers. The whole system is using under 40% of RAM, 10% CPU, for an average load of around 0.3. I find it hard to believe that the server is under-sized.
Thanks for any input on that issue !
