Hi If I insert the variable {{NUMBEROFEDITS}} into a page, the correct number of edits is displayed. However, when I then make an edit somewhere in the wiki, and then return to the page with the {{NUMBEROFEDITS}} variable, the value displayed doesn't change. Does anyone know why this is, and what can be done to force the variable to display the current value? Thanks in advance Derrick

I imagine that this is due to caching - you can reload the page with ?action=purge to force a cache update, or just turn off caching entirely in your preferences (under "Misc"). -- schnee

Thanks - is there any way to ensure that this does not happen for any user, regardless of their preferences settings? Also, would that setting mean that the site will run slower? On Sat, May 31, 2008 at 5:08 PM, Schneelocke <schneelocke(a)gmail.com> wrote:

Yes, you can turn the parsers Cache off by setting that. I have done such, and it makes no difference in speed. That's how fast the MediaWiki parser is. On May 31, 2008, at 9:39 AM, Schneelocke wrote:

I think you can turn it off by setting $wgEnableParserCache = false; in your LocalSettings.php (but I've never tried that myself). And yes, it likely will make the site run slower, although by how and whether it'll be noticeable very much depends. -- schnee _______________________________________________ MediaWiki-l mailing list MediaWiki-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/mediawiki-l

Yes, I've tried it and not noticed a reduction in speed. Thanks. On Sat, May 31, 2008 at 5:59 PM, Darren VanBuren <onekopaka(a)gmail.com> wrote:

I've just been told that having "$wgEnableParserCache => false;" in LocalSettings.php will significantly slow-down the site if it ever has more than a few users, which is why parsercaching exists in the first place - not that I know what 'parsercaching' is myself!

The parsercache is a cache which saves the parsed state of a page after MW has parsed it, and it's retrieved from the cache instead of being reparsed on each page view, up until the page is saved again, a or the job que or a user purges it. Believe it or not, but MediaWiki's parser is NOT fast. It is quite inefficient, it's a big kludge made up of a huge pile of regexes and other stuff. Not to mention that things like #ifexist and other things end up doing a costly query to the database. Which in itself is something that can quickly slow down a site by doing to many of those on every page view. ~Daniel Friesen(Dantman) of: -The Gaiapedia (http://gaia.wikia.com) -Wikia ACG on Wikia.com (http://wikia.com/wiki/Wikia_ACG) -and Wiki-Tools.com (http://wiki-tools.com) Derrick Farnell wrote:

I see - thanks for explaining that, which also explains why disabling the parsercache isn't a good idea if you have more than a few users using the wiki at the same time. On Sun, Jun 1, 2008 at 8:46 AM, DanTMan <dan_the_man(a)telus.net> wrote:
