I want to optimize my website's speed

my website address: [https://infozone24.com/](url) I optimized the sites's speed. but My another site called [https://bangla.infozone24.com/](url) is not optimized using the previous formula. I am using wp rocket, Cloudflare,web-p image converter.
please help me with some good suggestions.

Review the two site URLs and the reported WP Rocket, Cloudflare, and web-p image converter setup, then determine whether the problem is within this repository's Go WebP decoder or encoder scope. The issue names no file, test, reproducible failure, or concrete change, so a completion check cannot be defined from the report.
