Hii I have copied this issue from a post katos
I am going through the same. Please guide how to improve these things.
Anyway, to the topic at hand:
1) Your site is not utilising a CDN, and so you're relying on the server to serve assets, which is why your TTFB is pretty slow.
Use a CDN for all static assets: 0/100

2) You are loading unused resources:

3) You are also chaining critical requests:

You need to reduce the size of assets on load:

4) Consider changing your default homepage. For example: (tested using GTMetrix)
