Very slow processing time using SSL Native Channel Strip 2

Hi, did anyone notice this?

I did a simple test comparing it with protools:

using 25 tracks in a new project, on both DAWs, without any type of processing.
I inserted one instance of SSL Native Channel Strip 2 into each channel.
Mixdown on Cubase = 22 minutes
Bounce to disc on Protools = 6 minutes

can someone confirm this?
thanks in advance
