Hello,
I have made some profiling loading my mediawiki main page (
http://www.twenkill.net/wiki/ ) wich use phptal monobook skin and is set
to use the french language. For profilling I used "Advanced php profiler".
<snip>
CPU:
1/ looks like languagefr->ucfirst use about 20% of the total script time
for the sole purpose of uppercasing the first char of a given string by
calling strtr(). Maybe the strings could be declared as utf-8 and a php
function like uppercase() called instead ? I think Tim Starling looked a
bit at this.
2/ wfprofileout use 5% although it's an empty function. Using single
quote instead of double seems to have improved it a bit :)
3/ do_html_entity_decode use close to 4% maybe it could be replaced by
the php function html_entity_decode() that looks to make the same task
(php >= 4.3.0)
I profiled a bit with language set to en and the page:
http://www.twenkill.net/wiki/index.php/Parser_Benchmark
With profiling disable the wfprofileout and wfprofilein functions still
use about 7% of cpu time.
Although they don't use a lot of cpu time, both are called about 800 times.
