iMovie Macbook Pro not using full potential

[BlackZ]

Hi guys,

Today I started to export my first iMovie project and when I export the movie it seems it is only using 50% of the CPU (looks more like it is only working on 1 core) but when I check the activity monitor it shows it is working on 2.

I have an SSD 4GB Ram and Core duo on my Macbook pro.

Is there a way to check if the MBP is using its full potential?
Right now I can perfectly work and watch movies without interference but the export takes very long, what if I just want to make sure the export goes the fastest?

Hi,
Sometimes an application using just 100% of just one core will seem to be using 50% of both cores, simply because the Process jumps from one core to the other very fast to avoid heating just one of the cores. (i'm not very good at explaining )

If not that, it could be that your hard drive doesn't send the data fast enough for your CPU, but if it's exactly 50%, chances are the first explanation is the right one.
