-====== Apache ======
+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
-</code>
-   * **Disable unnecessary PHP variable**
-<code>
-allow_call_time_pass_reference = Off
-magic_quotes_gpc = Off
-register_long_arrays = Off
-register_argc_argv = Off
-allow_url_fopen = Off
-expose_php = Off
-disable_functions = symlink,shell_exec,proc_close,proc_open,dl,passthru,escapeshellarg,escapeshellcmd,openlog, apache_child_terminate,apache_get_modules,apache_get_version,apache_getenv,apache_note,apache_setenv,virtual, phpinfo

-   # Don't compress images
-   SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
-   SetEnvIfNoCase Request_URI \.(?:exe|t?gz|zip|bz2|sit|rar)$ 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

-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.
