response-time

I am building an autocomplete functionality for my site and the Google instant results are my benchmark.

When I look at Google, the 50-60 ms response time baffle me.

Google Response time
They look insane. In comparison here’s how mine looks like.

Server response time

To give you an idea my results are cached on the load balancer and served from a machine that has httpd slowstart and initcwnd fixed. My site is also behind cloudflare

From a server side perspective I don’t think I can do anything more.

Can someone help me take this 500 ms response time to 60ms? What more should I be doing to achieve Google level performance?
