-A little guide to increase the performance of a friendica site
-**************************************************************
-
-At first
-========
-
-Feel freee to ask the friendica support at
-<https://helpers.pyxis.uberspace.de/profile/helpers> if you need some
-clarification about the following instruction or if you need help in any
-other way.
-
-System configuration
-====================
-
-Please go to /admin/site/ on your system and change the following values:
-
-* Set "JPEG image quality" to 50.
-
-This value reduces the data that is send from the server to the client.
-50 is a value that doesn't influences image qualitity too much.
-
-* Set "OStatus conversation completion interval" to "never".
-
-if you are having many OStatus contacts then completing of conversations
-can be very time wasting. The downside: You won't see any answer in
-OStatus conversations.
-
-* Set "Path for lock file" to an empty folder outside your web root.
-
-Lock files help avoiding the situation that several background processes
-run at the same time.
-
-For example: It can happen the the poller.php is working longer than
-expected. When there would be no lock file than maybe several instances
-of poller.php would run at the same time - which would slow down the
-systen and would affect the maximum numbers of processes and database
-conenctions.
-
-Please define a full file path that is writeable by the web server
-process. If your site would be located at "/var/www/sitename/htdocs/"
-you maybe could create a folder "/var/www/sitename/temp/".
-
-* Enable "Use MySQL full text engine"
-
-When using MyISAM (default) this speeds up the search.
-
-* Set "Path to item cache" to an empty value outside your web root.
-
-Parsed BBCode and some external images will be put there. Parsing BBCode
-is a timewasting process that also uses much CPU speed.
-
-You can use the same folder like you used for the lock file.
-
----------
-!Warning!
----------
-
-The folder for the item cache is cleaned up regularly. Every file that
-exceedes the cache duration is deleted. If you accidently would point
-the cache path to your web root then you would delete your webroot!
-
-So ensure twice that the folder only contains temporary content that can
-be deleted at any time.
-
-You have been warned.
-
-P.S. It happened to me :)
-
-Plugins
-=======
-
-Active the following plugins:
-* Alternate Pagination
-* Privacy Image Cache
-* rendertime
-
-Alternate Pagination
---------------------
-
-Description:
-
-This plugin reduces the database load massively. Downside: You can't see
-anymore the number of pages.
-
-Administration:
-
-Go to the admin settings of "altpager" and set it to "global".
-
-Privacy Image Cache
--------------------
-
-Description:
-
-This plugin is prefetching external content and stores it into the
-cache. Besides speeding up the page rendering it is also good for
-keeping the privacy of your users, since embedded pictures would be
-loaded from your site and not from a foreign site (that could spy on the
-IP addresses).
-
-Additionally it helps with content from external sites that are having a
-slow performance or that are aren't online all the time.
-
-Administration:
-
-Please create a folder named "privacy_image_cache" and "photo" in
-your web root. If these folders exists then the cached files will be
-stored there. This has the great advantage that your webserver will
-fetch the files directly from there.
-
-rendertime
-----------
-
-This plugin doesn't speed up your system. It helps analysing your
-bottlenecks.
-
-When enabled you see some values like the following at the bottom of
-every page:
-
-Performance: Database: 0.244, Network: 0.002, Rendering: 0.044, Parser: 0.001, I/O: 0.021, Other: 0.237, Total: 0.548
-
-* Database: This is the time for all database queries
-* Network: Time that is needed to fetch content from external sites
-* Rendering: Time for theme rendering
-* Parser: The time that the BBCode parser needed to create the output
-* I/O: Time for local file access
-* Others: Everything else :)
-* Total: The sum of all above values
-
-These values are showing your performance problems.
-
-Webserver
-=========
-
-If you are using apache pease enable the following modules.
-
-Cache-Control
--------------
-
-This module tells the client to cache the content of static files so
-that they aren't fetched with every request.
-
-Enable the module "mod_expires" by typing in "a2enmod expires" as root.
-
-Please add the following lines to your site config in the "directory"
-context.
-
-<IfModule mod_expires.c>
- ExpiresActive on
- ExpiresDefault "access plus 1 week"
-</IfModule>
-
-See also: http://httpd.apache.org/docs/2.2/mod/mod_expires.html
-
-Compress content
-----------------
-
-This module compresses the traffic between the webserver and the client.
-
-Enable the module "mod_deflate" by typing in "a2enmod deflate" as root.
-
-See also: http://httpd.apache.org/docs/2.2/mod/mod_deflate.html
-
-PHP
-===
-
-FCGI
-----
-
-When using apache think about using FCGI. When using a Debian based
-distribution you will need the packages named "php5-cgi" and "
-libapache2-mod-fcgid".
-
-Please refer to external documentations for a more detaillied
-explanation how to set up a system based upon FCGI.
-
-APC
----
-
-APC is an opcode cache. It speeds up the processing of PHP code.
-
-When APC is enabled, friendica uses it to store configuration data
-between different requests. This helps speeding up the page creation
-time.
-
-Database
-========
-
-There are scripts like tuning-primer.sh <http://www.day32.com/MySQL/>
-and mysqltuner.pl <http://mysqltuner.pl> that analyse your database
-server and that are giving hints on values that could be changed.
-
-Please enable the slow query log. This helps being aware of performance
-problems.
