1 A little guide to increase the performance of a friendica site
2 **************************************************************
7 Feel freee to ask the friendica support at
8 <https://helpers.pyxis.uberspace.de/profile/helpers> if you need some
9 clarification about the following instruction or if you need help in any
15 Please go to /admin/site/ on your system and change the following values:
17 * Set "JPEG image quality" to 50.
19 This value reduces the data that is send from the server to the client.
20 50 is a value that doesn't influences image qualitity too much.
22 * Set "OStatus conversation completion interval" to "never".
24 if you are having many OStatus contacts then completing of conversations
25 can be very time wasting. The downside: You won't see any answer in
26 OStatus conversations.
28 * Set "Path for lock file" to an empty folder outside your web root.
30 Lock files help avoiding the situation that several background processes
33 For example: It can happen the the poller.php is working longer than
34 expected. When there would be no lock file than maybe several instances
35 of poller.php would run at the same time - which would slow down the
36 systen and would affect the maximum numbers of processes and database
39 Please define a full file path that is writeable by the web server
40 process. If your site would be located at "/var/www/sitename/htdocs/"
41 you maybe could create a folder "/var/www/sitename/temp/".
43 * Enable "Use MySQL full text engine"
45 When using MyISAM (default) this speeds up the search.
47 * Set "Path to item cache" to an empty value outside your web root.
49 Parsed BBCode and some external images will be put there. Parsing BBCode
50 is a timewasting process that also uses much CPU speed.
52 You can use the same folder like you used for the lock file.
58 The folder for the item cache is cleaned up regularly. Every file that
59 exceedes the cache duration is deleted. If you accidently would point
60 the cache path to your web root then you would delete your webroot!
62 So ensure twice that the folder only contains temporary content that can
63 be deleted at any time.
67 P.S. It happened to me :)
72 Active the following plugins:
73 * Alternate Pagination
82 This plugin reduces the database load massively. Downside: You can't see
83 anymore the number of pages.
87 Go to the admin settings of "altpager" and set it to "global".
94 This plugin is prefetching external content and stores it into the
95 cache. Besides speeding up the page rendering it is also good for
96 keeping the privacy of your users, since embedded pictures would be
97 loaded from your site and not from a foreign site (that could spy on the
100 Additionally it helps with content from external sites that are having a
101 slow performance or that are aren't online all the time.
105 Please create a folder named "privacy_image_cache" and "photo" in
106 your web root. If these folders exists then the cached files will be
107 stored there. This has the great advantage that your webserver will
108 fetch the files directly from there.
113 This plugin doesn't speed up your system. It helps analysing your
116 When enabled you see some values like the following at the bottom of
119 Performance: Database: 0.244, Network: 0.002, Rendering: 0.044, Parser: 0.001, I/O: 0.021, Other: 0.237, Total: 0.548
121 * Database: This is the time for all database queries
122 * Network: Time that is needed to fetch content from external sites
123 * Rendering: Time for theme rendering
124 * Parser: The time that the BBCode parser needed to create the output
125 * I/O: Time for local file access
126 * Others: Everything else :)
127 * Total: The sum of all above values
129 These values are showing your performance problems.
134 If you are using apache pease enable the following modules.
139 This module tells the client to cache the content of static files so
140 that they aren't fetched with every request.
142 Enable the module "mod_expires" by typing in "a2enmod expires" as root.
144 Please add the following lines to your site config in the "directory"
147 <IfModule mod_expires.c>
149 ExpiresDefault "access plus 1 week"
152 See also: http://httpd.apache.org/docs/2.2/mod/mod_expires.html
157 This module compresses the traffic between the webserver and the client.
159 Enable the module "mod_deflate" by typing in "a2enmod deflate" as root.
161 See also: http://httpd.apache.org/docs/2.2/mod/mod_deflate.html
169 When using apache think about using FCGI. When using a Debian based
170 distribution you will need the packages named "php5-cgi" and "
171 libapache2-mod-fcgid".
173 Please refer to external documentations for a more detaillied
174 explanation how to set up a system based upon FCGI.
179 APC is an opcode cache. It speeds up the processing of PHP code.
181 When APC is enabled, friendica uses it to store configuration data
182 between different requests. This helps speeding up the page creation
188 There are scripts like tuning-primer.sh <http://www.day32.com/MySQL/>
189 and mysqltuner.pl <http://mysqltuner.pl> that analyse your database
190 server and that are giving hints on values that could be changed.
192 Please enable the slow query log. This helps being aware of performance
