Improving the Speed of XenForo

Sorry, I mispoke. I am referring to saving 400kb from my benchmark rating. Bandwidth is not something I am concerned about.

Using gtmetrix.com I get an F for Leverage browser caching. Looking at their help page for this:

http://gtmetrix.com/leverage-browser-caching.html

I was wondering what others have done to improve this.

If you are using WHM/cPanel, go into your website's WHM and then go to EasyApache.

Then go to the exhaustive options list and click deflate. Then save.

Afterwards, add this to your root .htaccess file :)

Code: 
# Insert filter
SetOutputFilter DEFLATE

# Netscape 4.x has some problems...
BrowserMatch ^Mozilla/4 gzip-only-text/html

# Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4.0[678] no-gzip

# MSIE masquerades as Netscape, but it is fine
BrowserMatch bMSIE !no-gzip !gzip-only-text/html

# Don't compress images
SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary

# Don't compress already compressed stuff !
SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar|swf)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .pdf$ no-gzip dont-vary

# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary

I have found Google Adsense to increase requests and load time considerably. Deferring Javascript seems to be the best way to improve your YSlow grade.
 
Anybody, please check this code:
Code: 
# START: MOD_EXPIRES
ExpiresActive On
# Set Images to Expire After a Month
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"

ExpiresByType image/x-icon "access plus 1 month"
# Set CSS/JS to Expire After a Month
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"

#SetOutputFilter DEFLATE
AddOutputFilter DEFLATE xhtml html htm php css js xml xsl txt plain javascript x-javascript ico
# END: MOD_EXPIRES

Yes, it reduces the time on the first page rendering. That is what Google and other search engines are using to check the speed of websites. Google have been very open about the fact that search engine rankings use the speed of a website as a factor. Their PageSpeed service advises Javascript to be moved to the bottom.

Just FYI - if your page already loads in a reasonable amount of time, making it slightly faster isn't going to make you rank any better. It's more about if your page is so slow that it gives users a bad experience (think like a page that takes 30 seconds to load), your ranking for things will be pushed down. It's more about the user experience, not the actual speed of the site loading (but in some cases, they can be connected when your site is really, really, really slow).

Moving JavaScript to the end of the page isn't going to make XenForo load so much faster than it gives an sort of significantly better user experience... and that is what Google is ultimately talking about.
