How can I optimize my production website for better performance and server efficiency?

[Leehong]

Hello everyone,

I'm currently maintaining a live website:

345winpk.com

I'm interested in improving the overall performance and efficiency of my production website.

I'm looking for advice on topics such as:

• Server optimization
• Cache configuration
• HTTP/2 and HTTP/3 optimization
• Brotli compression
• PHP performance tuning
• Image optimization
• Reducing server response time
• Security best practices

If experienced administrators or developers have suggestions after reviewing the website, I'd appreciate your recommendations.

Thank you for your time.
