I have done a bit of testing with Speedstep turned off and on (both on
mains supply). The performance of the laptop appears to be significantly
reduced with Speedstep turned off. The application I work on compiles in
11 seconds with Speedstep turned on and 30 seconds with it turned off!
From the comments provided I wasn't really expecting this. Any ideas?
