While history is more and more large, the browser became more and more slow.

I love epiphany browser.
It's very quick when I have clean the history data. But while history is
more and more large, the browser became more and more slow.Can you
change the browser not to load history before it be used.
Otherwise,the urlbar list is to long.
My english is poor becase I am chinese, but I hope you can understand my
mean.
Thanks to all developers.
