Pagespeed en Yslow

Hoi,

Met GTMetrix loop ik vrijwel met elke Joomla site tegen deze 2 items op die niet optimaal zijn in Yslow. Meestal blijven ze rond de 77 %, Grade C
Pagespeed komt echter wel rond de 96 %, Grade A

Total pagesize is 590 kb wat in mijn ogen niet overdreven groot is voor bewerkte template met slider etc.

Aanvulling op de htacces file:

Citaat:

<IfModule mod_expires.c> FileETag MTime Size AddOutputFilterByType DEFLATE text/plain text/html text/xml text/css application/xml application/xhtml+xml application/rss+xml application/javascript application/x-javascript ExpiresActive On ExpiresDefault "access plus 1 seconds" ExpiresByType text/html "access plus 600 seconds" ExpiresByType text/css "access plus 604800 seconds" ExpiresByType text/javascript "access plus 216000 seconds" ExpiresByType application/xhtml+xml "access plus 600 seconds" ExpiresByType application/javascript "access plus 216000 seconds" ExpiresByType application/x-javascript "access plus 216000 seconds" ExpiresByType image/x-icon "access plus 2592000 seconds" ExpiresByType image/jpeg "access plus 2592000 seconds" ExpiresByType image/png "access plus 2592000 seconds" ExpiresByType image/gif "access plus 2592000 seconds" </IfModule>

Iemand suggesties hoe om dit te verbeteren ?

mvg.
