# [Plugin: W3 Total Cache] Help with Compression!

 * Good afternoon everyone.
 * So I have a CentOS VPS running Nginx and WordPress 3.6. Nginx is my web server,
   and is NOT just a front end proxy for Apache, which is common it seems.
 * Everything works great with my site, but I have recently come back to using W3
   Total Cache. My goal is to improve my sites PageSpeed performance (Google), and
   there are currently three big things throwing red exclamation marks.
 * 1.) Enable Compression
    PageSpeed Insights is showing about 30 files (looks to
   be mostly JS and some CSS) that can be compressed to for a 71% reduction. The
   estimated reduction is 567Kb.
 * 2.) Leverage Browser Caching
    There are about 30 pages/files that have either
   no expiration or a very short expiration.
 * There is a third red mark, but I am not concerned with it just yet. So I have
   W3 Total Cache in place, using Page Cache (Disk Enhanced), Minify (Manual – Disk),
   Database Cache (Disk), Browser Cache, and I’m also using CloudFlare (CloudFlare
   is only being used for managing DNS currently, as it is not acting as a CDN).
 * In regards to compression, I have the following:
    –Browser Cache settings– -General–
   Enable HTTP (gzip) compression, enabled -CSS & JS – Enable HTTP (gzip) compression,
   enabled -HTML & XML – Enable HTTP (gzip) compression, enabled -Media & Other 
   Files – Enable HTTP (gzip) compression, enabled
 * What other settings should I be looking for? Also in the Browser Cache settings,
   the Expires header lifetime for all of them is set to 31536000 seconds, so why
   does PageSpeed see several pages/files with no expiration?? Is this because of
   using Nginx and not Apache?
 * Thanks.

 * Well, I got it working.
 * I had:
    gzip on
 * Set in my Nginx.conf file, but I didn’t have any MIME-types specified, so it 
   was only doing gzip for text files, and not CSS or JS. I added this line:
    gzip_types
   text/plain text/css application/json application/x-javascript text/xml application/
   xml application/xml+rss text/javascript;
 * Right below gzip on and PageSpeed is much happier.
 * In regards to issue number two about Browser caching, that is also something 
   I resolved in my nginx server config with this line:
    location ~* .(ogg|ogv|svg
   |svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar
   |bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ { expires max; log_not_found 
   off; access_log off;
 * Easy fixes, outside of W3TC.
