 * If we compare ACF to Metabox there is a huge difference in the memory usage.
 * I tried installing most of Metabox addons and it showed no significant increase.
 * When ACF was enabled it increased by 2MB in RAM. Which is a lot more RAM usage
   than Meta Box.
 * Are you guys aware of that?
 * If we have 100 visitors on the site and we use ACF it is using 200MB in RAM just
   from your plugin. It adds up really fast.
 * I really dig your plugin and plan to buy the Pro version for my agency. But I
   hestitate because it will be eating a lot of resources.
 * And native support for custom database tables for performance would be great 
   for perfromance on top of this! Like Metabox has.
 * Plugintests shows some interesting stuff too.
 * Meta Box (49.5KB memory):

 * —
 * ACF (979KB memory):
 * [https://plugintests.com/plugins/wporg/advanced-custom-fields/latest](https://plugintests.com/plugins/wporg/advanced-custom-fields/latest)
 * That’s a huge difference.

 * Hi [@jonte98](https://wordpress.org/support/users/jonte98/), ​Iain here, the 
   product manager for ACF over at WP Engine.
 * Thanks for raising these concerns. We have a performance task on our backlog 
   and will add this to it, but we’ll look into the increased memory issue.

 * Is this on the frontend of the site or in the wp-admin?
 * Will keep you posted.

 * [@polevaultweb](https://wordpress.org/support/users/polevaultweb/) It’s site-
   wide. I can’t however see what it looks like when I’m logged out. I’m using Query
   Monitor to measure.
 * I’d like to let you know that saving everything regarding ACF in a custom db 
   table would help performance. And conditionally load the plugin code to only 
   when it’s used.
 * It seems like it’s loading the entire plugin site-wide right now.
 * On the front-end, it’s only required for the code that picks up the values from
   the DB to run for example. And all the back-end stuff is mainly required only
   on new posts and the ACF related setting pages.
