unfortunately my backend loading time jumps from 1sec to about 8.7 seconds as soon as I activate your "Insight core" plugin (v188.8.131.52). Everything else is working fine. The problem occurs on 2 different web spaces and on localhost - my wordpress installation is completely new.
Could you please have a look into this?
There are many reasons why a WordPress website is slow.
1. Use of too many plugins
The more plugins you use, the more resources your site needs. Thus, only use the ones that you need and trust. Disable all unused plugins to save the resources. Remember to update all plugins to latest versions.
2. Use of too many large images
Modern websites use a lot of big images. Vistors love it. However, too many of them on a page can increase the loading time.
Thus, make sure the page does not load too many images and images should be in the correct size.
3. Not cached
If you haven’t used a caching plugin, use it now. It greatly enhance the performance of your site. Two most popular caching plugins for WordPress are W3 Total Cache and Super Cache. Depends on your experience, choose the one you need.
If possible, use a CDN to host images and media files.
4. Not too powerful host
If you are using a shared host, bear in mind that it has limited resources. If you run a complex theme, such hosts may not handle well. Therefore, check your hosting capacity and increase it if possible.
Ofcourse, theme will slow a bit when activate "Insight core" plugin because after activated, all the theme functions will be load for customer use.
Hope the information above can help you a bit.
If there is another reply (than the generic one) to pixelsafari_net's question, I'd be more than happy to read it as well.
Thank you, Babette
