I posted some code before https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=625

I haven't really investigated impact of interseption. I my past experience
of rendering tables without Seam it was slow too.

I've seen it too, but I'm not talking here about client side.
I'm clocking renderding phase on server side. (JSF Phase listener
displays timing of all JSF phases on server side).
