NewPP parser report
NewPP is an abbreviation for "New PreProcessor" (new at the time of Tim Starling's 2008 parser rewrite for MediaWiki 1.12, that is). One is most likely to find it at the bottom of the HTML source of wiki pages, referring to the preprocessor report that contains statistics on what resources were used to render the page, and usage of various parsing-related quotas (such as number of expensive calls, or number of preprocessor tree nodes).
On a Wikimedia site it will look something like this:
<!-- NewPP limit report Parsed by mw1252 Cached time: 20170617200920 Cache expiry: 2592000 Dynamic content: false CPU time usage: 0.100 seconds Real time usage: 0.153 seconds Preprocessor visited node count: 501/1000000 Preprocessor generated node count: 0/1500000 Post‐expand include size: 50861/2097152 bytes Template argument size: 121/2097152 bytes Highest expansion depth: 9/40 Expensive parser function count: 4/500 Lua time usage: 0.032/10.000 seconds Lua memory usage: 1.73 MB/50 MB -->
followed by a per-template transclusion expansion time report and a debug message with the parser cache key.
See w:Wikipedia:Template limits for details on what the lines mean.
User script to make the report visibleEdit
The following snippet (to be stored in custom user JavaScript) will make the NewPP parser report appear on every content page at the bottom:
$('.mw-parser-output').contents().filter(function () {
return this.nodeType == 8 && /^\s*(NewPP|Transclusion|Saved) /.test(this.data);
}).replaceWith(function () {
return $('<pre>', { dir: 'ltr' }).text($.trim(this.data));
});
