I have a website which written by using ASP.NET. I hosted this website in USA ( Kansas city ) with Quad Core Processor and 8Gb RAM( Dedicated Server: 1GBPS Speed Line). Also my website is running through cloudflare CDN. I am using update panels in my webpages to do asynchronous page request to server.
eg: When user select an item from a dropdown menu getting records that related to selected item.
I access this site from long away from server ( Near to India ). So now the problem is it will took at least 3 to 4 seconds to update my content which are inside update panels.
So According to my knowledge I believe CDN only accelerates static contents of the website. So how about these dynamic data? How major websites like Facebook and Linked solve this problem?
If I run website from local ( my PC ) it is really fast.
