Nginx Nginx PageSpeed Domains Large Waiting Time.

I have installed Centminmod latest beta and wordpress + woocommerce site in a server with only 1 account

---

While loading it takes a long time to load the website so i checked the timing and found there a big block of waiting time



I never encountered this kind of issue with Apache. before. is this related to nginx and DNS TTL for now i have set the DNS TTL for 100sec

 

Since i have moved my wordpress from another site.
I haven't used centminmod wp install i just restored my wordpress from old server.

 

Hi,

With the below config i was successfully able to bring it down from 6000 ms to 3000 - 4000 ms
max of 5000ms which only if load it first time. and after that its around 3000 - 4000 MS still not sure whats wrong

here is the config files

As of now i am using gtmetrix.com to test.

 

Hi.

I had issue opening forums after my last post.

for now i have installed WP Super Cache and now its bit better.

I have no idea on how to use the site test link which you said.
