I’m a developer for the website UniformMarket, which is built on WordPress. Recently, I’ve been facing issues with the website’s speed, and I’m looking for advice on how to optimize it effectively.

Specific Issues:
Page Load Time: The homepage and key landing pages take too long to load.
Render-Blocking Resources: PageSpeed Insights indicates that there are render-blocking resources.
Image Optimization: Despite using plugins for image compression, images seem to load slowly.
Caching: I’m using a plugin, but I’m unsure if it’s configured optimally.
Database Optimization: The database appears to be slowing down the site, particularly during peak traffic times.

Questions:
What are the best practices for optimizing a WordPress site’s speed, particularly for e-commerce sites like UniformMarket?
Are there specific tools or plugins that you recommend for identifying and resolving speed issues?
Are there any advanced techniques or configurations (e.g., server-side optimizations, database indexing) that could help improve the site’s performance?
What are common pitfalls to avoid when optimizing website speed?

Any detailed guidance, step-by-step instructions, or resources would be highly appreciated. Thank you in advance for your help!

What I’ve Tried So Far:
Enabled gzip compression
Implemented lazy loading for images
Minified CSS and JavaScript files
Used a content delivery network (CDN)
