Websites hosted on Amazon S3 loading very slowly

I have an application which is a static website builder.Users can create their websites and publish them to their custom domains.I am using Amazon S3 to host these sites and a proxy server nginx to route the requests to the S3 bucket hosting sites. I am facing a load time issue.As S3 specifically is not associated with any region and the content being entirely HTML there shouldn't ideally be any delay.I have a few css and js files which are not too heavy.

What can be the optimization techniques for better performance? eg: Will setting headers ? or Leverage caching help? I have added an image of pingdom analysis for reference.

Also i cannot use cloudfront as when the user updates an image the edge locations have a delay of few minutes before the new image is reflected.It is not instant update,hence restricting the use for me. Any suggestions on improving it?

S3 HTTPS access from a different region is extremely slow especially TLS handshake. To solve the problem we invented Nginx S3 proxy which can be find over the web. S3 is the best as origin source but not as a transport endpoint.

By the way try to avoid your "folder" as a subdomain but specify only S3 regional(!) endpoint URL instead with the long version of endpoint URL, never use https://s3.amazonaws.com

One the good example that reduces number of DNS calls is the following below:

https://s3-eu-west-1.amazonaws.com/folder/file.jpg

Your S3 buckets are associated with a specific region that you can choose when you create them. They are not geographically distributed. Please see AWS doc about S3 regions: https://aws.amazon.com/s3/faqs/

As we can see in your screenshot, it looks like your bucket is located in Singapore (ap-southeast-1).

Are your clients located in Asia? If they are not, you should try to create buckets nearer, in order to reduce data access latency.

About cloudfront, it should be possible to use it if you invalide your objects, or just use new filenames for each modification, as tedder42 suggested.
