My current build times look like this:

culmus.log: 30
cup.log: 74
gnome-alsamixer.log: 191
gtkglext.log: 342
lablgtk2.log: 288
libclass-whitehole-perl.log: 32
libgetopt-java.log: 75
libhtml-fromtext-perl.log: 32
speakup-cvs.log: 33
 

When simple packages require around 10 seconds to build on pbuilder without
UML.
So, it is definitely slower.
In my observation, package downloading through network, and 
running ./configure seems to be very slow.
Maybe because they are syscall-intensive tasks.
I have an impression that compilation process using gcc etc aren't that
much affected.

I've not yet tested with SKAS patch.
