Special:Badtitle/NS90:Forums/Admin Discussion/SMW implementation + MW code drop megathread/reply
MediaWiki 1.24.1 has some major incompatibility problems for us. 1.25 has some promising improvements, but is not yet stable. So for now I have held off on upgrades and taken a look at optimizing settings to work better for us.
SMW initiative seems to be going along fine. I am doing a mass update to the category links: this takes hours to run. This should slowly start trickling in SMW stuff to places it was added.
I am collecting metrics and figuring out where the hardware/software needs are to let the site work best.
