Long time to load - problem with TTFB

[Mattpl]

Hi, I'm looking for help.
Here is test result: http://www.webpagetest.org/result/171019...9d7a6d06b/

TTFB:1.450s
For now I have made opt. for my apache server and still the same. Apache 2.4 , PHP-FPM 5.6, MariaDB 10.01, dedicated server. In my opinion server is good but code not and this generate long time.

I have second website at the same server (Wordpress) and there load time is good. Results: http://www.webpagetest.org/result/171019...89f8fe5a1/

TTFB:0.185s
