Achievo/Howto/Developers/Speed up Achievo

This page will describe some tricks to speed up Achievo. As of version 1.4 (not released yet) there are some performance updates done in Achievo it self.

Use gzip compression

In atkconf.inc you can add the following config:

$config_output_gzip = true;

Use apache deflate module

With the apache deflate module it is possible to compress the output of the files that are send to the client.

Use apache expires module

With the apache expires module it's possible to change the cache behaviour of files.

 <ifModule mod_expires.c>
 ExpiresActive on
 
 # cache common graphics for 3 days
 ExpiresByType image/jpg "access plus 3 days"
 ExpiresByType image/gif "access plus 3 days"
 ExpiresByType image/jpeg "access plus 3 days" 
 ExpiresByType image/png "access plus 3 days"
 
 # cache CSS for 24 hours
 ExpiresByType text/css "access plus 24 hours"
 
 # cache javascript for 24 hours
 ExpiresByType text/javascript "access plus 24 hours"  
 ExpiresByType application/x-javascript "access plus 24 hours"
 ExpiresByType application/javascript "access plus 24 hours"
 
 </IfModule>

Use apache headers module

With the apache headers module it's possible to change the expires headers of files.

 #set expires header to 2 days
 <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
   Header set Cache-Control "max-age=172800, public"
 </FilesMatch>

Create selector nodes

If your nodes has multiple manytoone relations, make sure the destination node doesn't contain too many relations. If this is case, just make a simple selector node for it with only the fields needed to get a decent descriptor.
