As described, compressor compresses only once, but delivers often.

Add this to your localconf.php and uncomment the required .htaccess rules.
$TYPO3_CONF_VARS['BE']['compressionLevel'] = '9';

This produces gzipped files.

Also you should send expires headers:
<FilesMatch "\.(js|css)(\.gzip)?$">
         <IfModule mod_expires.c>
                 ExpiresActive on
                 ExpiresDefault "access plus 1 month"
         </IfModule>

         # ETag
         FileETag MTime Size
         <IfModule mod_headers.c>
                 FileETag none
                 Header unset Last-Modified
         </IfModule>
</FilesMatch>

Kind regards
Steffen
