I've been playing recently with some firefox extensions for web developers:
FireBug: https://addons.mozilla.org/es-ES/firefox/addon/1843 PageSpeed: http://code.google.com/intl/es-ES/speed/page-speed/index.html YSlow: http://developer.yahoo.com/yslow/ and found that enabling certain options in the koha's apache VirtualHosts configuration would improve a lot koha's performance in bandwidth use. Only the opac startup page bandwidht usage goes from 368.5K to 118.3K. Enable http compression using mod_deflate --------------------------------------------------------------- Document this command for enabling this in Debian/Ubuntu # a2enmod deflate and add this lines to koha-http.conf in both VirtualHost definitions SetOutputFilter DEFLATE SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip I specify not to apply useless compression to compresed images. Further options could be used. See http://httpd.apache.org/docs/2.0/mod/mod_deflate.html Enable better caching features by setting explicit expiration far in the future for static content using mod_deflate ---------------------------------------------------------------------------------------------------------------------------------------------------------------- Document this command for enabling this in Debian/Ubuntu # a2enmod expires and add this lines to koha-http.conf in both VirtualHost definitions ExpiresActive On ExpiresDefault "modification plus 1 year" as mod_expires only applies to files in the filesystem it is safe to rely on modification date. This could be fine-tuned, for example on a per filetype basis (see http://httpd.apache.org/docs/2.0/mod/mod_expires.html). ----- PageSpeed in particular offers some recommendation on image sizes and provides an optimal image file for substitution. This could be analised.
