How to improve the performance of a Friendica site
|
|
==============
|
|
|
|
* [Home](help)
|
|
|
|
Feel free to ask in the [Friendica support forum](https://helpers.pyxis.uberspace.de/profile/helpers) if you need some clarification about the following instructions 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 quality too much.
|
|
|
|
Set "OStatus conversation completion interval" to "never".
|
|
|
|
If you have many OStatus contacts then completing of conversations can be very time wasting. The downside: You won't see every comment in OStatus threads.
|
|
|
|
Set "Path for lock file" to an empty folder outside your web root.
|
|
|
|
Lock files help avoid the possibility of several background processes running at the same time.
|
|
|
|
For example: It can happen that the poller.php takes longer than expected.
|
|
When there is no lock file, it is possible for several instances of poller.php to run at the same time - which would slow down the system and affect the maximum numbers of processes and database connections.
|
|
|
|
Please define a full file path that is writeable by the web server process.
|
|
If your site is located at "/var/www/sitename/htdocs/" you could maybe create a folder "/var/www/sitename/temp/".
|
|
|
|
Enable "Use MySQL full text engine"
|
|
|
|
When using MyISAM (default) this speeds up 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 time wasting process that also makes heave use of the CPU.
|
|
You can use the same folder you used for the lock file.
|
|
|
|
**Warning!**
|
|
|
|
The folder for item cache is cleaned up regularly.
|
|
Every file that exceeds the cache duration is deleted. **If you accidentally point the cache path to your web root then you will delete your web root!**
|
|
So double check that the folder only contains temporary content that can be deleted at any time.
|
|
You have been warned.
|
|
|
|
Plugins
|
|
--------
|
|
|
|
Active the following plugins:
|
|
|
|
Alternate Pagination
|
|
Privacy Image Cache
|
|
rendertime
|
|
|
|
###Alternate Pagination
|
|
|
|
This plugin reduces the database load massively.
|
|
Downside: You can't see the total number of pages available at each module, and have this replaced with "older" and "newer" links.
|
|
|
|
Go to the admin settings of "altpager" and set it to "global".
|
|
|
|
###rendertime
|
|
|
|
This plugin doesn't speed up your system.
|
|
It helps to analyze your bottlenecks.
|
|
|
|
When enabled you see some values at the bottom of every page.
|
|
They show your performance problems.
|
|
|
|
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
|
|
|
|
Apache Webserver
|
|
--------
|
|
|
|
The following Apache modules are recommended:
|
|
|
|
###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 configuration in the "directory" context.
|
|
|
|
ExpiresActive on ExpiresDefault "access plus 1 week"
|
|
|
|
Also see the Apache [2.2](http://httpd.apache.org/docs/2.2/mod/mod_expires.html) / [2.4](https://httpd.apache.org/docs/2.4/mod/mod_expires.html) documentation.
|
|
|
|
###Compress content
|
|
|
|
This module compresses the traffic between the web server and the client.
|
|
Enable the module "mod_deflate" by typing in "a2enmod deflate" as root.
|
|
|
|
Also see the Apache [2.2](http://httpd.apache.org/docs/2.2/mod/mod_deflate.html) / [2.4](https://httpd.apache.org/docs/2.4/mod/mod_deflate.html) documentation.
|
|
|
|
PHP
|
|
--------
|
|
|
|
###FCGI
|
|
|
|
When using Apache think about using FCGI.
|
|
In a Debian-based distribution you will need to install the packages named "php5-cgi" and "libapache2-mod-fcgid".
|
|
|
|
Please refer to external documentation for a more detailed 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 analyze your database server and give hints on values that could be changed.
|
|
|
|
Please enable the slow query log. This helps to find performance problems.
