Why I site?

Tell me, please, what is this first row in the developer console when you open the website.

This is the server response time??
What affects the time? It is necessary php scripts to optimize or a problem in the server?

TTFB is great. The client from the server is waiting for the first byte, and the server at this time, the script handles.
customer is that is a visitor?
the server processes a script - that is the reason to look in the established engine, php scripting and mysql database? - mossie16 commented on August 19th 19 at 22:46

: server, engine, php, mysql. Podgruzki static content (.html .jpg) see if there's a lot of waiting the first byte. Then unpack the php script that runs on the page, etc. - vicenta51 commented on August 19th 19 at 22:55

You have a great time Time To First Byte. To reduce this time, you need to:
  1. If you are using php to generate a page, you first check his work, optimize php scripts
  2. If the page is dynamic, and not plain html, you need to check the database
  3. If 2m the first points, everything is super, then check the working of iron, maybe not enough resources or zhetsky slow
