[WebERP-developers] Increase speed loading images from a subdomain

[Pak R. <pak...@gm...>]

Hi all:

I have been investigating a bit about increase of page loading time and it
seems like we can improve it if we store images in a subdomain. I attach
some links I found about it:
http://css-tricks.com/images-on-a-subdomain/
http://www.techinfoblog.net/host-images-on-sub-domain-to-increase-page-load-speed-of-your-wordpress-blog/
http://www.inmotionhosting.com/support/edu/opencart/319-using-a-subdomain-to-store-your-images-in-opencart
http://cathyreisenwitz.com/blog/2010/11/15/image-seo-host-images-on-subdomain-or-subfolder/

With more and more scripts in webERP using images, I wonder if it makes
sense we study this option.

I thing the only change in webERP should be changing the
$_SESSION['part_pics'] to a absolute address instead of relative, but not
sure if there are problems related to the use of absolute addresses

We should be able to access images in paths like:
 $_SESSION['part_pics'] = "http://images.mydomain.com/"
 $_SESSION['part_pics'] = "http://images.mydomain.com/webERP"
 $_SESSION['part_pics'] = "http://images.anotherdomain.com/"

Does it make sense to you?

Regards,
Ricard

Hi Ricard,

Does it work just changing to an absolute address? I think it should... 
without looking.

Hi:

in config table we store just the relative path from webERP base
"companies/mycompanyname/part_pics"

A quick search and:
SystemParameters.php: Needs to convert the data entry for part_pics_dir
into a text (as user can enter any URL)

In GoodsReceived.php line 164 should be deleted the $RootPath . '/' part
In PO_items.php line 1221, 1222 should be deleted the $RootPath . '/' part

Besides that I think we are done. Am I overlooking at details, or are we on
the right path? I'm a bit afraid of this kind of small changes with wide
consequences

Regards,
Ricard

*Hi, Richard:*

           Thank you for your efforts to improve webERP's performance. 
           I'm wondering if this method really solve your problem?

          If you separate two domains in one server, it'll make a burden
instead of improve efficiency IMHO. 

          The solution in your provided link is to utilize client side's
resource to load data from more than one resources. But in the same server,
if we introduce more jobs, the load of the server will be double, does that
make sense? 

          Or I just overlook some important point?

          Thanks and best regards!

           Exson

Hi all:

I was thinking to "give the freedom" to place the part_pics folder
anywhere, but not the other subfolders in the company folder. The part_pics
folder should contain only JPG images. I'm not an expert in server
security. So, all scripts will be located where they are now, and the
default setting for$_SESSION['part_pics_dir'] can be the same one as it is
now, so no security issues. If the admin wishes to place it somewhere
else... he has the chance to do it.

Regading Exson's POV, I really have no idea. I just found those links as a
side effect setting up an ecommerce site, tried it, and it seems to work
ok. Fact is pages load faster, and being a LAMP installation I think it can
be also applicable to webERP.

So, I left the final decision to the guru's final votes. For it? / Against?

Regards,
Ricard

*Hi, Richard:*

         Thank you for your great efforts!

         I support to change the relative path to the domain name for those
picture etc.  Have no idea if it improve the performance to add a
sub-domain.
         
         Thanks and best regards!

         Exson
