Told you that I fixed a big bad bug :-)

Nah, the speedup is real :-)

Both. These are often blocks that did not go through when they were tried the 
first time. But also, there is less traffic when these blocks are requested, 
thus the delays that nodes introduce are longer. The combination of these two 
effects makes the speed go down at the end.
