Hello,
I asked to remove {{ messages from en.wikipedia skin
( Mediawiki:aboutsite, Mediawiki:copyright, Mediawiki:pagetitle ),
and we gained 7% of performance. In these hard times when we're again
somewhat overloaded even small bits count.
If you're a sysop on big wiki and notice a message that is used on
skin and has {{ in it, do not hesitate and remove it. In future we
might hack that 10 (or more) largest wikis definitely won't be able
to use {{ in skin messages.
Every 1% saved results in multiple kilo$ in savings.. ;-)
