Media Server and Image problems

[felixdpg]

Hi all:

 

Recently I was finding many ways to reduce the load time of my web, and looking for media server configuration. I create 3 subdomains in order to reduce the load of my shop, create symlink for this subdomains to the root folder of the shop, but, when the page load all the image, css and jscript are missing!

 

The steps:

 

1. Create 3 subdomains : static1.mydomain.com, static2.mydomain.com static3.mydomain.com

2. Create symlink: ln- s rootshop /static1

                             ln- s rootshop /static2

                             ln- s rootshop /static3

3. Add this subdomains to the media server option in performance

 

In theory when the page load all of the content are distributed across subdomains (with symlinks) but does not appear work for image, css, etc.

 

Please, how can I solve the media server with the subdomains to reduce the load time of the shop?

 

thanks in advance

not sure why you are creating symbolic links, but ignore media server for now.   what happens when you enter the following in a browser?

 

static1.mydomain.com/README.md

 

do you see the contents of the README.md file from the root prestashop directory?  Or do you get a 404 page not found?

Hi bellini13:

 

The problem was solved making only a symbolic link to /modules /img and /themes. Now I can see the web as I have it, but the load time was no reduce so much. Do you know a best practice to reduce the load time?

 

thanks in advance

load time for each individual resource on your server would not change by using a local media server.  in fact it could increase load time.

 

most browsers work by opening 4 connections to each different domain, and then using those 4 connections, it downloads all the media files (ie.  css, js, images etc..)

 

however by adding 3 media servers, you have now allowed the browser to open 12 more (3 * 4), for a total of 16 connections.  Overall load time is reduced so long as their are enough resources available to handle 16 connections (both on the client side and the server side).

 

Now if you used a CDN as media servers, you would have offloaded the delivery of those media files to some other remote host.  This means your server has less work to do, it would use less bandwidth, cpu and memory etc..
