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.
