doesn't look like that -- generated page /index.ucw (examples head
page) is only twice larger than /admin/index.ucw, but it is 15 time
slower. as i understand it does lengthy initialization. further using
links appears to be faster.

(btw, with araneida and aserve backends examples published at "/"
don't work when admin application works. is that ok?)
