V-Studio 20 netbook performance and track count

Hi,

I'm considering purchasing the V-Studio 20 and have a couple of questions regarding the performance when running on Netbooks:

i) I understand that Guitar Tracks supports a maximum of 16 stereo tracks which is sufficient for my needs. However, can anyone confirm that this is realistic on a netbook or I am likely to run into stuttering problems before this? 

ii) How does the included TTS-1 VSTi perform on a netbook, specifically will it make the CPU choke? 

iii) What is a realistic number of VST effect instances can I expect to use before the CPU chokes?

Thanks

Ben
