Prestashop speed configure [Dedicated Server]

[meliansolutions]

Dear presta users,

I have bought a dedicated server with the following specifications and installed PrestaShop 1.5.5:

Operating system: CentOS 6 64bit + Plesk 11.5

CPU: 4 x 2.5 Ghz

RAM: 4 Gb

RAID 1

Traffic unlimited

Php 5.4

 

PHP.INI VALUES:

memory_limit 1000M

max_execution_time 300

max_input_time -1

post_max_size 25M

upload_max_filesize 25M

max_input_vars = 10000;

 

I have created a file in conf.d for nginx with the following values:

  proxy_connect_timeout       2000;

  proxy_send_timeout          2000;

  proxy_read_timeout          2000;

  send_timeout                2000;

 

 

For some reason, i am having serious speed issues and for some reason, each and every time i am trying to add attributions, i get a gateway timeout from nginx which i am going crazy trying to configure it properly. I have tried several values for several options but no performance results.

There are quite a lot of attributes but as the website will run alone on that server, i am thinking there should not be any problem.

 

The website will be at http://printnu.com and you can check a test product at http://printnu.com/index.php?id_product=2&controller=product

 

Any kind of help would be greately appreciated as i do not understand why this website is working so so slow without basicly anything in it.

 

NOTE:

i have memcached configured

Template cache set to "Never recompile"

Cache ON

All CCC options configured

No media servers as i could not manage to set that up

Mcrypt set to Use Rijndael with mcrypt lib

 

 

Thank you in advance for the help.

 

LATE EDIT: It seems that after nginx gives gateway error, the attributes are still appearing one by one. Either there is some kind of limitation or i need to upgrade the server even more which is a little bit silly considering that the server specifications are a lot.
