[Rt-devel] Perfomance glitch with localization.

[Ruslan U. Zakirov]

Autrjus, sorry, it's wrong report about perfomance because init takes 
long time.

I'm playing around perfomance and get home page from 2sec max to 1,4 
with standard amount of tickets in My* blocks.

Will fill in report tonight.
