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. - - - ExpiresActive on - ExpiresDefault "access plus 1 week" - - -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 -and 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.
