This issue has been covered many…many…many times.
Please do a quick search or just look down the main FCP page.
Correct Qmaster setup…
open system preferences>select Apple Qmaster> Select “Stop Sharing” >
Select “QuickCluster With Services” > select “Options for Selected Service >
change number of instances to 8 > Click “Start Sharing”
I will warn you that 4gb will not get you too far with 8 cores. It is most
efficient with 2gb per core. Try 4 instances instead of 8 if 8 is still slow.
HDV is also just dog slow as well…no matter what machine. 4 hours of
uncompressed or DVCPROHD would be a breeze.
Also…just for kicks try After Effects CS3 if you want to see your 8 core beauty
brought to its knees. 95% utilization on ALL cores. You can barely move a window
around because it is sucks up so much resources. Adobe seems to “get it” in that
regard, but setting up Qmaster correctly helps a lot.
