Hi there,

I've got questions around Wiki Farm setup, I'm not sure if it's the right place to ask the question. If there is a better channel, feel free to say so.

In Wiki Family page [1] there is a quote saying

It is recommended to use a different DB for each wiki (By setting a different $wgDBname https://www.mediawiki.org/wiki/Special:MyLanguage/Manual:$wgDBname for each wiki). However if you are limited to a single database, you can use a different prefix ($wgDBprefix https://www.mediawiki.org/wiki/Special:MyLanguage/Manual:$wgDBprefix) to separate the different installs.

But it's not detailed why it's recommended. I'd like to know if there is any downside of using the prefix strategy (peformances, upgrades, etc) ?

Regards, Manuel
