Problem with the speed and rendering af a page

[vega83]

I tried to compile Bfilter without debug configuration. BFilter now is very very fast, but I think that the problem is my network.
About the problem with the rendering, I evalueted that this is an IE problem.
In fact I can see the same problem also without the use of Bfilter.
With Mozzilla Firefox insted there aren't problem of rendering.
Thank you very much for all
