 * Hi
 * Activated on the main site of a multisite, the activation produced a 140% CPU
   usage on my dedicated server.
 * Just to mention 😉 Had to deactivate the plugin after server crash !
 * 🙂

 * Hello,
 * Many thanks for this feedback.
    Are you using WordPress 4.9.6?
 * But een if you’re not using it, I can figure why and how this can lead to such
   a CPU usage issue. This plugin only creates a widget, a shortcode and adds one
   CSS and one JS file to your WordPress installation.
 * But I really want to check this issue deepier, so could you provide me some additional
   informations please?
    – WordPress Version – What do you did after plugin activation:
   you used the provided Shortcode? you used the provided Widget? Both? None (it
   broke everything before you can manage to use it)?
 * Many thanks for your answers [@aphrodite](https://wordpress.org/support/users/aphrodite/)
   
   Cheers, Jb

 * Hi,
 * I tested the plugin on a multisite installation and it works fine. No particular
   CPU usage increase.
 * I let this ticket open a couple of day, so do not hesitate to get back to me 
   with some further infos 🙂
 * Cheers,

 * Hi ! 🙂
 * Yes to all. 4.9.6, and shortcode usage. No widget 🙂
 * Well, in fact, i cannot insure you that the plugin activatin IS at 100% the culprit.
   
   In fact, at the moment, i am still experimenting high CPU usage (a reactivated
   the plugin).
 * The 2 phenomenon are simultaneous but i am not able to confirm the cause/effect
   possibility.
 * The fact is that on THIS multisite it occures, but I am not able to reproduce
   the issue on another one on the same server.
 * Still digging 🙂
 * Thanks ! 🙂

 * Hi !
 * I think i found the culprit : PHP version 😉
 * And i reproduced the issue without problem : activating the plugin on a 5.6, 
   CPU explodes.
 * On 7.2, back to 1.56% ! 😉

 * Closing this topic since this doesn’t seems to be related to the plugin, but 
   merely on this specific installation.
 * Feel free to ask for any further information 🙂
