It appeared that page rendering (blocks rendering in particular) causes the most significant delays. You may view these files with any cachegrind viewer ( KCacheGrind or WinCacheGrind).

Profiling dump files (results) are avialable for download from here (). Profiling was done using XDebug PHP extension on the server side, while moodle/mod/forum/view.php?id=X page was open in browser. Next, we have done a brief investigation of what makes Moodle 2.0 that slow. Generated JMeter reports can be downloaded from here (csv files). You may notice Moode 2.0 is not as fast as its previous version - as results suggest, on the most pages we run test with, version 2.0 is significantly slower. (moodle2/mod/chat/chat_ajax.php?action=update) moodle/mod/chat/gui_header_js/jsupdate.php Next table shows the summary of perfomance on some pages:ħ.

* Navigation was slower than actual chat communication. The average page performance results (mean time in milliseconds spent on each page retrieved throughout the testplan) are shown in the table below: Web and database server are two different vhosts run on the same systems: Apache 2.2.16-3, php5 5.3.2-2, mysql-server 5.0.51a-24+lenny4. Static content retrieving (images, css) are not included in the testplan, so the time only reflects php script output rendering on the client side.Īll tests were done on dev-box: Intel(R) Core(TM)2 Duo CPU E8600 3.33GHz, 8GB RAM, Debian/GNU 'squeeze', Kernel: Linux 2.6.26-2-vserver-amd64. Test was done with 10 threads (simultaneous users) and each user made 5 posts in corresponding activity (in Quiz only one submission was done). Each testplan included all steps required to perform the task (logging in, navigating to required page, posting in chat/forum or submitting quiz). Having enhanced JMeter testplan generation plugin originally developed by James Brisland, we used it to run performance tests on Forum, Chat and Quiz activities in 1.9 and HEAD (2.0) versions.

we have done some measurements recently and I think it worth sharing our findings with Moodle community.
