Summary0001717: Yahoo! YSlow and Google PageSpeed: server settings to improve web application performance
DescriptionThis ticket is from a Tiki perspective but will be useful for any web app.

These sites provide performance scores for websites:
* http://www.webpagetest.org/ [^]
* http://gtmetrix.com/ [^]
* http://www.showslow.com/ [^]
Steps To Reproduce1- Install a Tiki
2- Visit tiki-admin.php?page=performance
3- Activate advanced features
4- Turn on GZip output and all minifications of JS and CSS

Provide your site URL to http://gtmetrix.com [^] and check results for both YSlow and PageSpeed. Some are application dependent, and some are server dependent.

As of 6.6 Beta 1, the following could be improved:
* PageSpeed: Enable gzip compression
* PageSpeed: Enable Keep-Alive
* YSlow: Compress components with gzip

Ideally, they would be settings in the web server admin panel, defaulted to on.

Thanks!

As per http://stackoverflow.com/questions/970151/how-to-check-mod-deflate-is-enabled-in-apache, [^] it looks like mod-deflate is enabled but YSlow and PageSpeed report otherwise.

To help with the investigation, some additional info:

Tiki ships with a _htaccess file. This is activated either by renaming or symlinking from .htaccess to _htaccess. We know the file is taken into account because other parts of it are functional.

Here is the part of the _htaccess file related to deflate_module:

<IfModule deflate_module>
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript application/javascript
</IfModule>

Thanks!

For the record, this code works for Tiki on ClearOS 6.x, but I am concerned it may cause issue in other versions:

<IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript application/javascript
    <filesMatch "\.(js|css|html)$">
        SetOutputFilter DEFLATE
    </filesMatch>
</IfModule>

So it looks like there may not much that ClearOS can / should do differently.

Closing here and moving to here:
In htaccess, IfModule deflate_module is not picking up for ClearOS Help
https://dev.tiki.org/item5502 [^]

I will test with other PHP web apps to see if they are OK, and will re-open this if ClearOS could do anything differently.
