I am looking to renew an existing client site: https://celias.no/
Today is uses Avada and I am looking into a slimmer and speedier theme. I made the test site https://fragmentsofawalk.com and found various themes I wanted to test out with focus on speed.
Following plugins are active:
Akismet, All in One WP Security, Caldera Forms, Companion Auto Update, Content Aware Sidebars, Custom Feeds for Instagram, Duplicator Pro, Elementor, FileBird Lite, Kadence Toolkit, PageSpeed Ninja, WooCommerce and WooCommerce Stripe Gateway.
How are you thinking we should do this? It would be great to review the plugins.
I don't think that's something I can do. It depends on your requirements for your projects. Personally I would try to measure the weight of the plugins individually, and see which are adding the most stuff, and then replace them with something lighter.
I don't know your requirements but I would guess many of the plugins do a lot of things that you don't use.
For example the theme you currently have activated looks to be one of the bigger themes. I ran the pingdom test and sorted the file requests by response body size descending (untick the rising box) and then you can see the biggest requests.
The top one is font-awesome.ttf. The theme is including the entire font-awesome library, but I suspect it's only using a few icons.
If you enable all your plugins then you could run the test again, see what plugin is using the largest files and then see if you can replace it with something more efficient.
