Hi Julia @JuliaLS I had a look at the store and tbh it wasn’t slow on my own ends. That being said, have you tried clearing all the cache and cookies on your browser and maybe even changing browser too?

Hi @JuliaLS

I have checked on your store speed: https://pagespeed.web.dev/analysis/https-juliaskreations-com/31kzjm7kah?form_factor=mobile

The analyzed site speed score is measured between 60 and 89, which indicates satisfactory performance.

  • For mobile, there are opportunities to enhance the speed score by improving the Largest Contentful Paint (LCP) metric. Currently, the theme settings require all images to load slowly, which affects this score. Please refer to the following link for more details: https://prnt.sc/xS_BMvRpBdcC

To address this issue, we recommend consulting with the theme developer.

  • Additionally, the First Contentful Paint (FCP) score could be improved by utilizing an Speed application. And we recommend to try this Avada SEO app, his app includes a Page Loading feature designed to enhance performance metrics here: https://prnt.sc/Nq3KcxUfouL1.

Here is the app link, you can check it out: SEO app

Hi Julia

I checked on PageSpeed Insights and found that the store’s speed is quite good (https://pagespeed.web.dev/analysis/https-juliaskreations-com/zuw46xgxuv?form_factor=mobile). I recommend you to contact the theme developer to reduce the LCP a bit, and then it will be fine

Hi Manuel,

Thank you for taking time to review my issue. Unfortunately, I’m still having very slow response time with the Desktop loading speed which is now at 21.14 secs. I’ve made no changes to my site and have even uninstalled unused apps and deleted old products. My overall speed has now dropped to 2.91 (moderate) which isn’t good.

Hi Bundler-Manuel,

I also forgot to mention that I cleared my cache and cookies on my browser along with trying different browsers. It doesn’t make sense how the speed changed overnight when nothing was changed on my store.

Hi LizHoang,

I tried the suggested app and there was no change with the speed. Thank you for taking time to review my issue.
