For en wikipedia and all non-big wikis at Wikimedia I've
done "alter table cur drop index cur_namespace". This index
was too often being used for queries like
Parser:replaceLinkHolders, the 500 article allpages subpages
and other things where namespace_title should be used. The
rest of the wikis will be changed during off peak read only
If not already done, I recommend that this index be removed
from all MediaWiki installations by the installer. May
already have been done - I recall past discussion of this.
As far as I can tell, a new 1.4beta installation does not include this index,
but an upgrade from 1.3x does not remove it automatically yet.
No longer an issue, since cur is dead. ;)
