We developed a new app using Remix as recommended for SSR and to improve LCP. However, our LCP scores are quite poor. On our Shopify page, it shows about 8 seconds, and during onLCP testing, it's between 3 to 5 seconds. I also ran tests on webpagetest.org ( https://www.webpagetest.org/vitals.php?test=250512_AiDc3D_6R3&run=2&cached=0#lcp), and the results were not satisfactory either. It seems that our gadget's assets and JS might be blocking the rendering process.
Could you help identify what might be causing this issue? Our app is built using Gadget's Remix template. Is there anything we can do to improve this situation, or is it mainly due to the cold boot problem?
Before considering the cold boot addon, I would like to understand its pricing and the next steps to implement it. Additionally, I want to confirm if the slowness is solely due to the cold start issue or if there could be other underlying issues affecting performance.
