-I had the same problem. after fowolling all the advices above , i came across this:# enable resulting html compression# For security reasons, mod_php is not used on this server. Use a php.ini file for php directives #php_flag zlib.output_compression onMy host is bluehost.So in ~public_html/php.ini , change this line:zlib.output_compression = offtozlib.output_compression = onNow it is super fast.Thank you all

+===== optimization =====
+  * **disable DNS Look Up**
+  * **MaxClients** ( 512 )
+  * **KeepAlive**
+     * Disable KeepAlive connections (by setting KeepAlive to Off)
+     * Shorten the KeepAliveTimeout value to something like 3 seconds for instances), reducing the maximum simultaneous opened connections to 768
+  * **Compress HTTP Content**
+  * **Turn off unwanted services** - There are a few services and/or features that you will want to turn off or not allow. All of these services can be disabled in the httpd.conf file. Those services/features that could cause the most issues include:
+       * Directory browsing. This is done within a directory tag (the document root is a good place to start) using the Options directive and is set with “-Indexing”.
+       * Server side Includes. This is another feature that is disabled within a directory tag (using Options directive) and is set with “-Includes”.
+       * CGI execution. Unless your site needs CGI, turn this off. This feature is also set within a directory tag using the Options directive, with “-ExecCGI”.
+       * Symbolic links. Set this inside a (surprise, surprise) directory tag with “-FollowSymLinks”.
+       * None. You can turn off all options (in the same way you set the above) using “None” with the Option directive.
+   * **Disable unused modules**
+   * **Restrict access**
+<code>
+Order Deny, Allow
+Deny from all
+Allow from 192.168.1.0/16
+</code>
+   * **Limit request size** - Denial of service attacks are always a possibility when you allow large requests on Apache. Apache has a directive, LimitRequestBody, that is placed within a Directory tag. The size of your limit will depend upon your Web site’s needs. By default, LimitRequestBody is set to unlimited.
+   * **Hide Apache’s version number**
+<code>
+ServerSignature Off
+ServerTokens Prod
+TraceEnable Off
+</code>

+   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

+This configuration will compress everything except for images. Of course, you can’t test this with curl, but you can test it with Firefox and [[https://addons.mozilla.org/en-US/firefox/addon/3829|LiveHTTPHeaders]]. If you don’t have Firefox handy, you can try a very handy **[[http://www.gidnetwork.com/tools/gzip-test.php|web application]]** that will give you the statistics about the compression of your site’s data.
