This is definetly a big improvement though exact measurement is kind of 
difficult. The most important effect is that reparsing causes memory and also 
potentially disk I/O. Both activities become really expensive in case other 
processes are using the same ressources concurrently. They are rather cheap 
in case of an otherwise idleing machine. (Using an idle ressource does not 
slow down the overall processing too much, basically it means primarily some 
latency but no bandwidth consumption)

Due to the fact that measurements are much easier with an otherwise idle 
machine is much simpler it is hard to quantify the effect.
