Title: High CPU usage Last modified: March 6, 2018 --- # High CPU usage * [j0bb13](https://wordpress.org/support/users/j0bb13/) * (@j0bb13) * [8 years, 2 months ago](https://wordpress.org/support/topic/high-cpu-usage-25/) * When adding around 24 pictures from our Media library (these are already being used with Final Tiles Grid Gallery), around 2 MB 6000 × 4000 each, to a gallery my browser became very unresponsive it took a minute to press the button to save the gallery. The CPU usage was through the roof, also loading the page where the gallery was on took a very long time. * PC: Windows 10 Chrome 64bit i5-6300HQ 8GB RAM * Server: Apache 2.4.29 Nginx 1.13.6 (reverse-proxy) Php 7.1.14 * There is some optimisation to be done with this plugin before we can use it 😉 - This topic was modified 8 years, 2 months ago by [j0bb13](https://wordpress.org/support/users/j0bb13/).

I’m not seeing this behaviour actually on my dev configuration. * Thank you * Thread Starter [j0bb13](https://wordpress.org/support/users/j0bb13/) * (@j0bb13) * [8 years, 2 months ago](https://wordpress.org/support/topic/high-cpu-usage-25/#post-10044016) * In the admin panel mostly, and sorry, but I can’t give you the URL to our admin panel 😉 * I installed the plugin and created the first gallery. Then I tried adding the 24 jpg images and the browser tab froze and turned black after some time. I then closed the tab and went to the plugin again. This time I created a Gallery, added the pictures and clicked on a black screen where the Publish button used to be, and after a couple minutes it said something along the lines of “saved”. So I tried if the frontend would work properly. * Sadly, the page on the frontend with this gallery was also very slow. I have’t checked my CPU usage there since I assumed the gallery was loading the full 6000 × 4000 images, while 300 x 200 would have been plenty. Maybe the CPU usage was too high as well, but I just assumed it was loading the original images instead of a reasonable sized version. * These experiences already lead me to disable the plugin. Since it wasn’t usable we’ll stick with Final Tiles Grid Gallery for now. - This reply was modified 8 years, 2 months ago by [j0bb13](https://wordpress.org/support/users/j0bb13/). - This reply was modified 8 years, 2 months ago by [j0bb13](https://wordpress.org/support/users/j0bb13/). * [Diego](https://wordpress.org/support/users/greentreelabs/) * (@greentreelabs) * [8 years, 2 months ago](https://wordpress.org/support/topic/high-cpu-usage-25/#post-10044202) * > In the admin panel mostly, and sorry, but I can’t give you the URL to our admin > panel 😉 * I never meant to ask you for your admin panel URL (also useless without credentials 🙂 * In the admin panel I use the original size as background images for the blocks, so it makes sense if the browser stressed the CPU to render those hi-res images. * On the frontend the images are (clearly) resized so you should have not issue at all. * However, the plugin is really young (1 week) and all kinds of feedbacks are very welcome, thank you.
