Loading speed gone very low! but why?

Our speed went from 2.01 to 4 seconds…

We are using new apps like Elevar but they are saying that it has nothing to do with speed

WE cannot figure out what happened can someone help to identify the issue?

thanks so much

Hello @iroket I have checked your current speed in google page speed https://pagespeed.web.dev/analysis/https-www-theloomia-com/pmk3ijyc4i?form_factor=mobile 32/68

Here are the list of issues present in your store

  • Largest Contentful Paint image was lazily loaded
  • Largest Contentful Paint element 1,770 ms
  • Properly size images
  • Serve images in next-gen formats
  • Reduce unused JavaScript
  • Eliminate render-blocking
  • Minify JavaScrip
  • Ensure text remains visible during webfont load
  • Defer offscreen images
  • Reduce unused CSS

If you are unable to fix them feel free to contact me.

Store is loading pretty quickly for me. Google pagespeed is flagging 2 issues related to image formats and sizes:

Optimizing images and deferring 3rd party app javascript will have a noticable impact on the speed.

Hello @iroket ,

I have checked your website using the Google Page Speed Insight tool. It has a low score and needs to be improved, especially on mobile devices.

The following factors can impact the speed of your online store.

Currently, your website is experiencing a heavy load with a high Total Blocking Time (TBT). We need to do the following to improve website speed:

  1. Reduce the impact of third-party code
  2. Reduce JavaScript execution time
  3. Minimize main-thread work
  4. Avoid excessive liquid loops.

Some other factors:

  1. LCP (Largest Contentful Paint)
  2. Interaction to next paint(INP)
  3. Reduce JS Payload
  4. Migrate Tracking Codes To Google Tag Manager
  5. Properly Image sizes
  6. Preload Web Fonts.
  7. Use standard web fonts.
  8. Eliminate Render-Blocking Resources
  9. Ensure Text Remains Visible During Webfont Load
  10. Largest contentful Elements
  11. Reduce initial server response time
  12. Remove unused apps

By fixing these issues, you can improve the speed of your website.

Hi, @iroket
Based on https://pagespeed.web.dev/analysis/https-www-theloomia-com/hpqvxrg47i?form_factor=mobile Sudden performance drops are usually caused by recent changes rather than the platform itself. It is mainly caused by first contentful paint and Largest Contentful paint Reviewing what was added or modified just before the slowdown often helps identify the issue quickly.

Key areas to review :

Apps and integrations
Recently installed or updated apps are a common cause. Many apps inject JavaScript that loads on every page. Remove or disable non-essential apps and test performance after each change.

Heavy JavaScript execution: Large or complex scripts can block the browser from rendering content quickly, delaying page interactivity.

Main-thread work: Excessive computations and tasks on the main thread prevent smooth rendering and slow down user experience.

Unused JavaScript: Scripts that aren’t needed on the page still load, consuming bandwidth and slowing down rendering.

Unused CSS: Extra styles that aren’t applied increase render times and can cause layout shifts, impacting perceived speed.

Render-blocking scripts
marketing scripts can block the initial render if they load too early. Non-critical scripts should load after the page becomes interactive.

< script>

window.addEventListener(‘load’, function () {

const script = document.createElement(‘script’);

script.src = ‘https://example.com/non-critical-script.js’;

script.defer = true;

document.body.appendChild(script);

});

< /script >

Alternatively ,

If you prefer not to diagnose sudden performance drops manually, a performance optimization app such as Website Speedy helps identify scripts, assets, and recent changes that commonly impact load speed.
